Spent the morning with Obe and his father doing a whole lot of work stripping my engine down to find out what the problems were. Honestly guys if you know Obe and his father then you know the knowledge thy have and how darn good they are at working on these bikes, in only a few hours my motor went from being complete to being pulled apart and all faults located and ready to be fixed and they made it look like it was as simple as making toast!

I'm truly thankful for the hard work they have put into my engine today which was a hell of a lot, I didn't realise how much went into these engines and I thought I had some pretty good knowledge of engines and how they worked..... I was wrong.

Thanks again Obe and can't wait to get back into it and do some more hours!!!

    Guys

    What is the best way of lowering barrel down on complete pistons and rings.

    Is there a specific ring tighten tool to do this or can you manoeuvre with hands etc

    Do people insert pistons in barrel first and get into position to attach rods as a option ?

    Any comments would be much appreciated as just about to do this

        Russell posted something about charging issues the other day. Well I can't say by bike doesn't charge but if I run it with the lights on below 3k RPM and stopping at lights through the city the battery goes.

        I have taken some measurements to see what people can tell about what's normal and what's not.

        Ignition key off: 12.60

        Ignition key on kill switch off: 12.26

        Ignition key on kill switch on: 12.12

        Engine idling at 1000 RPM: 12.34

        At 2000 RPM: 13.28

        Anything above this RPM makes the voltage vary slightly above 13 volts but I didn't see it go above 13.50.

        Thoughts?

          Hi Y’all I have been doing a bit of Zinc plating thought id share the results. These are all the nuts, bolts, washers, and linkages etc. off the carbies. There usually lots of questions with a post like this so here goes answering a few of them. These are the steps I took to do the zinc plateing

          1. Clean of all the old zinc plating off the parts in hydrochloric acid.

          2. Clean any rust with ‘CLR’ solution.

          3. I cleaned my parts in a home made tumbler. The tumbler cost me $0, an old drill from council clean-up and a bucket. The tumbling media I used blasting grit (sand blasting grit), but you can use wire brush / wheel, buffing ect.

          4. Clean parts in a cloudy ammonia solution just before plating.

          5. Plating. I bought a kit from Jane Kits, you can buy the Zinc plating kit for $185 or $285 with a power supply (or weirdly just buy the components individually for $120) For a power supply I used a ‘Buck converter’ from eBay for $10. Which gives variable Voltage and Amp control.

          6. The parts are then dipped after the plating in a chromate solution which gives the gold colour to the parts. The are touch dry in 24 hour, but need to harden for about a week.

            So yesterday I ran that other F2 I have had sitting in my garage for a long time. Some minor issue but some big ones too.

            There is a bubbling sound coming form between the pipes in the front of the head. Maybe oil sound? There is oil there but not that much.

            Oil pressure varies from 30psi in very low idle to about 70 at about 4000 rpm.

            The main issue is the rattle noise. It rattles when it idles low and when I am in third or fourth gear. It gets very loud then.

            I have two videos here, the oil bubbling sound and the rattle. As I rev the bike it's hard to hear what I say but that's when i start going through the gears to 3rd or 4th.

            What do you think it is?

              I had a mishap today whilst I was ballancing carbies and I knocked my tank, that contained about 7 litres of fuel, off the bench it was sitting on and it landed upside down (just like Toast with Jam on it does) on the fuel cap, on a mat. I am so pissed off that words cant describe it, but I need to move on and fix it so I am looking for suggestions on how to "Pop" it back out from someone that's done it before and pereferably without repainting it. Any experts out there?

                  Hey all. Newbie here. Just looking into getting a cb750. There are quiet a few differences in the years but want peoples thoughts about all the different years. Obviously early ones are classic but what is handling, power and reliability like compared to the 80's and 90's version? I like the idea and looks of classic but im guessing the newer the more power, better handling and reliable they got? Thoughts?

                        Okay my fellow 750-4 owners here if a question.

                        I'm restoring my K2 and it has the original 4 into 4 HM341 pipes. One has some rust holes and the others are okay, but they need some repairs and rechroming.

                        There lies the problem - some say you can get them rechromed, others say no one will it as it stuffs up the chroming bath. Others say you can clean all the carbon etc. out first.

                        As yet, down here in Melbourne, no one seems to be able to give me an answer. I have contacted a number of re-chromers but not one had bothered to return my enquiries!

                        Given the cost of purchasing a new (read reproduction) set of HM341 numbered pipes I'm looking an alternative (repair).

                        Any suggestions members??

                          Hi guys and girls,

                          I've been riding a Yamaha R3 for the past two years and am wishing I bought the Honda CB400 instead! The 4cyl sound and "classic" styling beats the modern crotch rocket any day. Over the past year I have been slowly restoring a BJ42 Landcruiser to factory spec, and have been toying with the idea of starting a classic bike build next year when I finish the shorty 40.

                          Any assistance in finding a suitable bike, or hints in what to look for or how much to pay would be greatly appreciated. I studied mech eng and work as a field technician so am quick to pick up mechanical or electrical systems. Something that is mechanically sound but aesthetically rough would be ideal, I don't want to ruin a perfectly good factory spec bike.

                          Pic attached is of the style I'm hoping to achieve. I hope I'm not breaking any page rules, there isn't a pinned post of rules like most pages.

                            As it is appropriate to give members first option on other members bikes for sale, I thought I should let you know I am publicly putting my CB750K2 up for sale very soon.

                            I built this from parts I bought off a CB750 collector friend of mine. The original parts are all K2 so engine and frame numbers are both for that model build.

                            It is built as a mostly stock bike, no metal work and no frame mods. The cafe seat is a stock seat pan that fits and hinges as an original seat does.

                            The guards are slightly shorter, it has a billet top triple, clip on's, new gauges and smaller indicators. Headlamp and mounts are aftermarket.

                            The Tarrozi rear sets bolt on with no frame mods.

                            The engine was rebuilt by Mal Doswell so you know it is good. New pistons, rings, bearing shells. Bored out to 836cc and fitted with Yoshimura style 4 into 1 pipes. This engine has only just done 1,000km since rebuild.

                            Front brake master cylinder is ZX10, works well on the stock caliper.

                            Tank paint by Dan Henricksen, I have just ordered new side covers with the stock Honda badges for Dan to paint to match the tank.

                            The bike is on Melbourne and is sold with a RWC if sold in Victoria.

                              Rear Brake Rod Length. G'Day Gang, could one of you measure the length of your rear brake rod for me, mine is 52cm long from where it comes out of the clevis to the stopper that the spring sits against and I needed to remove the lever from the backing plate to get the rod into the lever. The other question relates to the Brake pedal lever where the brake rod attaches. Mine appears to be fouling the rear swing arm which doesnt seem to be correct?

                                    I don't care if he was drunk, high and just angry, this behaviour is unacceptable regardless. He even messaged some people directly to try to offend them when he was questioned about what he posted.

                                    He not only left the group but he also blocked me. I thought he was a nice guy.

                                    For the future, DO NOT POST sexualised content. There are other places for that and if you do post you will be at risk of being removed without a first warning.

                                    Let's focus on our bike talk and the greatness that bikes bring to us and how it unites us.

                                        About 2000km on the new motor - no idea on power output , hasnt been dyno yet because we were to put some miles on it first . It was meant to have CR29's but i think it might just be sold with the factory carbs .

                                        It will definitely be sent back to Lindsay checked / tuned and dynoed before its sold.

                                        So what do you think it would sell for as it is now

                                        and what do you think it is worth with the cafe seat and CR29'S on it ?

                                          Friends,

                                          This CB750 chopper was owned by one of my best friends Jimbo (Jimmy Helton) #JimboRidesAgain. I sold this very bike to him in around 1978 and then helped him re-chop it. When I first got out of school (actually before) I was building a few custom scoots and then moved toward racing motorcycles and cars. After Jimbo's death in 2007 on his Harley his wife Karen and daughter didn't want to sell his CB750 chopper because it went back to when him and Karen met and first dated. When she finally decided to sell it she called because my friendship with Jimbo went back to freshman year when he was the manager for the Northwest Cabarrus Jr. Varsity football team I played on. From then until his death he was one of the closest friends I ever had. My intention when we removed the chop from the garage corner was to leave it just as it was "in the day" with just a little cleaning and tuning. However the paint was just too far gone, so this will be a "tribute" build to a great friend for all of our friends to enjoy and dig up the good ol' memories. NEVER to be sold. I have tried to stay as "true" to the original build as possible. The Andrews Motorsports Facebook page or visit www.andrewsmotorsports.com has some more info, but at the moment the build is about 95% complete. The reason the "whole" chopper is not viewed is I plan on a "reveal" party with the old crew and anyone else that's interested.

                                          Thank you,

                                          Curt "Fatback" Andrews

                                              Chassis dyno run on my personal sunrise orange 74 CB750. The motorcycle is basically stock except for a stainless 4 into 2 into 1 system built at Andrews Motorsports. It also sports a set of cafe bars and 16" "Harley" rear wheel plus Hagon rear shocks. This motorcycle was a one owner "basement find" and what interested me about it was this while not "the one" is a replica of what I rode to high school.

                                                Hi Guys — Honda CB750 Four 69-78 Australia

                                                Hi Guys,

                                                Looking for some guidance from the gods of cb4s~!

                                                My brake light works but the stay light? Is that what it's called doesn't come on. So there's no stationary light but when I press the lever or the foot brake the light comes on fine. Any idea what may be the cause of this and how to fix it? For ur info, I tried checking if the line for the stay light is faulty and all cables coming out to the rear is working. I also tried if it was a faulty brake light but that all appears to work fine too when I plug it to my other bikes.

                                                I tried everything and am stuck now..... Checked fuses too and all working order.....

                                                Thanks in advance

                                                  My shop (Andrews Motorsports) is based on the East Coast of the USA in Concord North Carolina. We offer a lot of engine parts for the Honda CB750 SOHC series engines and other vintage motorcycles also. We ship Internationally almost daily. We have a complete engine machine, dyno and fabrication shop in house. In my early days just out of school I built "choppers" before it was the cool & hipp thing to do. I built my business on the performance side and now enjoy using the shop to also do some vintage work.Thanks again for your time and ride safe.

                                                      I am having rear brake dramas . The caliper is rubbing on the disc slightly. It seems solid but i cant figure out how / where it has moved .

                                                      I haven't pulled it apart, trying to get an idea of what im looking for ( assuming it's a common problem ).

                                                      Also the rear caliper jams on when its hot . Once it cools, it frees up ( jammed on cooled . it with creek water . )

                                                      If i dont use it , it stays cool / free .

                                                      I pulled the caliper apart . And clean it up . Bled it .

                                                      All seemed ok but it started doing it again .

                                                        Cast Iron brake discs - plain — Honda CB750 Four 69-78 Australia

                                                        Honda fours have lousy braking performance. The main reason is the poor grade stainless Steel used by Honda for the original brake discs.

                                                        These discs solve that, being that cast Iron has a much higher friction coefficient producing better braking with the same lever effort.

                                                        Every Honda four race bike uses cast Iron discs for this very reason. But they also help on road bikes

                                                        We can also fit them to your hub for an additional 150$

                                                          In reply to an earlier post, I dont know if the F series is the same, but for the K series rears , if the damping is kaput, there is a virtually zero cost fix I have used. (Thanks Google). Take the collets off & remove the springs. Turn them upside down. In the pedestal drill, drill a hole underneath where they bolt round the swinging arm lug. DONT MOVE them (leave them clamped in the pedestal drill vice, turn the drill press off & chuck up a tapered tap & tap the hole, turning the chuck by hand. Take them out the drill press & Flush them out by working them whilst the bottom is in a bucket of oil. Fill with (I think) 50mm of light oil. Screw in a tapered grub screw & whack them back on. You cant see the fix & the bikes still original. Ive seen some people do it from the side, but that looks sh*t to me.

                                                            My front forks are knackered . Very spongey and are pretty lose to bottoming out . Its like riding a pogo stick also .

                                                            I need a cheap fix . Also want to lower it too.

                                                            By the sound of it oil volume and weight seem to be the place to start . Adding spacers to get more preload has also been mentioned. Cutting the spring will also do the same thing and also lower it .

                                                            So .......what i am looking for is instructions specific to cb750s and your own experience.

                                                            Im happy to buy parts but dont want to spend 500 bucks just to throw it away 6 months later when i do the Gl1000 conversion.

                                                            I know its trial and error to get it to suit me but How much oil and what weight is a good starting point ?

                                                              I am considering 11'' for my f2 ( i think they are 11.4 )

                                                              Could you also give me a brand , price ,where you bought them and a bit of a review.

                                                              This will be my ' get me going setup ' for the next 6 - 12 months . I intend to give it the all singing, all dancing race spec setup when money allows

                                                              Sorry guys , i realise it is the same as my earlier post but after a bit of discussion i have decided to get some photos and a bit more advice

                                                                Hey lads , has any one lowered their 750 ??

                                                                How did you do it ? What parts did you use ? Who from ?

                                                                Both front and rear suspension are flogged .

                                                                Needs to be kinda cheap as i have a gl1000 front end to do up for it . And i also want to do a decent suspension set up for some track work / hill climbs . But life has gotten in the way once again . So im after a cheap fix for the next 6-12 months .

                                                                Im thinking shorter rear shocks ( black body / chrome spring )

                                                                Buy shorter springs or spacers / cut springs ? Thoughts ?

                                                                Emulators in the front .

                                                                Mine is an F2 . Are the rears different ??

                                                                  When I say project it has only had bits and pieces taken off. All running gear hasn't been touched except for carbs coming off to replace rubber manifolds. Exhaust is off cause I was gonna wrap it. It's a complete runner when I purchased it. Engine is in excellent condition. Frame has been powdercoated by previous owner. Tank and tail piece have been stripped getting ready to paint.The seat has been professionally retrimmed. I paid 4,500 for it and spent 400 on the seat alone plus various other parts. I'm willing to take a hit on it. Will take 3,500 for it. My loss is your gain. This will be a very very good bike when finished.

                                                                  Can take more photos if required.

I love the way it looks which is why I bought it without thinking! It's too big for me. It's in near useable, respectable condition for its age but would want a resto if you're fussy. Would want tyres and head tube bearings for using.

                                                                    I'd like $4000 for it, pretty firm.

                                                                      Hey guys ,

                                                                      Im having trouble getting my cb750 f2 to start after its been sitting .

                                                                      Its got a 970 big bore and a web cam .the motor is about 4 months old . I dont think that matters but mentioned just incase.

                                                                      It used to start first stab of the button . Now it fires first stab but wont start then just keeps winding over not firing. If you crack the throttle it wont fire . Throttle makes it worse , you can here its not having a bar of it .

                                                                      It used to start if i sprayed engine start but now even with the engine start it takes about 15 mins of fucking around. Spraying , starting , one or two coughs . Spraying , starting , coughing , swearing .

                                                                      It will usually flatten the battery before it starts . So then its spraying , pushing , running, jumping ,coughing , farting , stopping , swearing . Uphill pushing , repeating .

                                                                      Once it goes, it runs like a kicked cat . Rides fine all day but after 2 or 3 hours of sitting its hard to start . With a spray it will start after a few goes .

                                                                      Now probably an important fact . It is always on the kick stand but surely it can sit for a few hours without getting fuel drain .

                                                                      I think there is also an issue in the starter / solenoid department . I have some bits on the way .

                                                                      I'm hoping it isn't a carb issue because i dont want to spend money on them cause im after some CRs but life keeps getting in th way so its taking a awhile to scratch up the funds .

                                                                      Thoughts Gents ?

                                                                        Hi all, I am looking to clean/polish/paint my comstar wheels. I am restoring the CB750 F2 I have and I want to keep it all original.

                                                                        The spokes (if I can call them that) are painted silver from what I know. There is some very light and small spots of surface rust but on the inner side there is more rust.

                                                                        That's what I would like to fix.

                                                                        Have any of you restored comstars before? Is it possible to disassemble them?

                                                                        Thanks

                                                                          I am lucky enough to be able to ride the k1 to work everyday. It is not too far, Leichhardt to the CBD, which probably does the bike more harm then good but it has not missed a beat. Today I clocked up 17000 miles with 5000'm being put on in the last 15months. The bike always gets a lot of looks and approving nods but today while stopped at the lights turning left onto Sussex Street a city bus was turning left on to Erskine Road. The bus driver was feverishly beeping his horn and while I was on the right hand side of my lane he still had plenty of space to effect the turn. I looked towards the driver scowling under my helmet only to see a big shit eating grin on the drivers face while he turned the corner with one hand, the other giving a thumbs up. Always good to see someone appreciate the bike. I did tell my missus, who was on the back, that he was giving her the thumbs up, what she doesn't know won't hurt her.

                                                                            Hi guys,

                                                                            A question for those mechanically sound members for some advise.

                                                                            So I serviced my cb750 k4 6 months?8? Ago.

                                                                            I followed all the instructions in my manual.

                                                                            At that point this is what I did:

                                                                            1. Change the oil, oil filter and air filter.

                                                                            2. I used mineral based engine oil

                                                                            3. Changed new spark plugs

                                                                            All worked well and no problem but I built up a overheating problem I mentioned in a post before.

                                                                            I wasn't sure what it was and hadn't been able to find the problem. I went to repeat the above today only to realise that I had a lot lower amount of engine oil in my bike than the recommended 3.5quarts which works out to be 3.3 litres. I only had about 2.3. Could this have been the cause of overheating?

                                                                            Not sure why it was so low, I'm not leaking anywhere.

                                                                            Any thoughts?

                                                                            Thanks in advance

                                                                              What do you use to clean all the years of neglect of your hubs and spokes etc ??

                                                                              I was hoping for a spray on , hose off idea .

                                                                              Im not that keen on hours of autosol , rubbing and polishing. Because i just want to assemble it . Test it . Ride it . Then disassemble for the big rebuild with new rims , spokes, tubes , seals bushes , the big polish etc .

                                                                              I would how ever like it presentable so i can take it on a ride if one comes up .

                                                                              Thanks.

                                                                                I am looking to do the GL1000 front end conversion on my cb750 F2 . Basically a very straight forward swap to give me period correct spoked wheels .I will then adapt some big brembos or A.Ps .

                                                                                I hope to run a few meetings in Period 4 historic racing.

                                                                                I would prefer a Ducati Front End with the brembos on it if there are any available.

                                                                                If any one has either of these or an idea on another simple conversion that would give me 37mm or 38mm tubes with spoked wheels. Please let me know .

                                                                                I can sort the brake conversion if necessary.

                                                                                Thanks for the input

                                                                                  So my f2 is still having an issue with the suprise neutral.

                                                                                  Going up through the gears it grabs a ''neutral'' - out of gear big rev !! It does it down sometimes too . It also is occasionally a pain to get actual neutral. Some times very stiff in the selection .

                                                                                  Engine build told me it was the fact that i have clip ons and aren't shifting properly. ( lever angle ) definitely not the case .

                                                                                  Does anybody know what is causing it and how do i fix it . Whats involved ??

                                                                                  It is due to go on the dyno and will speak to the engine builder . I'm just trying to figure out what it could be , so i know what I'm talking about . Cause I'll be pissed if they reckon I'm paying to remove and strip it .

                                                                                  It has a brand new clutch, has had full rebuild including under cut dogs and gear box bearings . Was supposedly looked at to have the fault rectified. Was told it just needed a bit of a tidy up and is all fine . It's not fine !

                                                                                  Thanks

                                                                                    I have a 78 f2 and put them in the pillion peg holes. I put them on yesterday. It is a touch to far back now not only do i get numb hands in about 15 mins but i feel now im fighting to keep myself going over the handle bars

                                                                                    ( not really but i feel like im fighting it not riding it )

                                                                                    When i put the clip ons on it took about 40 mins before my hands started playing up . I also started holding myself up with my core / stomach which helped heaps but now it is all on my arms .

                                                                                    So im thinking ........Put the cafe seat on , then move the pegs to suit me and make some custom clip ons .

                                                                                    This bike is for tearing around the streets , the odd hill climb and race meeting .its not a long distance bike

                                                                                    I road it to the Woolshed classic the other day , with the standard pegs and it was fine ( approx 2.5 hours ride with fuel stops ). That's about as far as it will ever go .

                                                                                    The lever on the brake spigot is a tad agriculture. .....its just a get me going piece untill i work out what im doing with them . Its rough but it works

                                                                                    Thanks

Here I was thinkin that it had been a while I'd been waiting for my 836 setup to show up from Ray so I sent him a wee query to see if he'd remembered to put it all into the post. And of course that meant that it was waiting for me in the letterbox when I got home this arvo. Must say I'm pretty impressed with the finish of the stuff and for 110 schmackers including postage I reckon I've done alright. So, cheers and apologies for doubting you Raymond and thanks for the more than fair deal comrade (Y)

                                                                                          Any one got a cb that is a street fighter during the week and a track brawler on the weekends ???

                                                                                          Ive got the motor done , i need to get shocks and brakes done ( backwards i know , but it made its own decision on the motor )

                                                                                          So the shocks are flogged and need to be done sooner rather than later.

                                                                                          I want adjustable shocks and if they have external canisters i need them remote so i can hide them .

                                                                                          What shocks / springs are you running ?? Brands / rates etc

                                                                                          Trouble is , may be now is the time to consider brake swap / front end ( didnt want to do that just yet ).

                                                                                          Also it needs to be period correct so i can race it in classic stuff .

                                                                                          Any thoughts that are helpful for what I am trying to build ???

                                                                                          Surely some one in the last 30 year has done this

                                                                                            I need to clean one of my bikes which has been sitting for a long time. It's covered in an oily grime, there is some sludge on the frame and engine.

                                                                                            In the past I used that Armorel wheel cleaner to remove the grime and clean it. However this product seems to cause some surfaces to oxidise.

                                                                                            What would you recommend I use? I don't want to use anything which could invite corrosion.

                                                                                            What about truck wash and CT18?

I need some help please, to value this bike (even just a rough idea/price range) if I were to sell it. I have it on another site. I am not sure if I will be selling or not as I don`t know what I would get for it if I were to sell. So I can not name a price & was hoping that someone mite want it enough to slap an offer down, or that I mite at least get an idea based on what members think. Regardless off value, Surely the record shown below (pics) is more than just a little impressive?? A Bloke that was already in his 40s, never raced, but wanted to have a go, so built the bike & scorred all those placings in a 4 year period. DAMN! hit wrong button & it bloody posted it up before I added all pics. I can`t edit pics in, so will have to add the others as pics in comments.

I want to do everything right not to have more problems. I realized that the cylinder gasket presents different format from the engine block format. I suspect that the oil comes up through these holes left by the gasket, rising by nails and ending in the head, which always leaks through the fins near exhaustion. can anyone tell me if this influences on my problem? Sorry for the English

                                                                                                  Hey guys ,

                                                                                                  Bike is nearly ready . But need a few ideas .

                                                                                                  Ive put a new loom in it so dont want to cut it . It also has an oil cooler on it .

                                                                                                  My question is what did you do to make the loom look tidy around the head stock area .

                                                                                                  Most of it was jamed in the back of the head light . I have a new light with not quite so much space in it , so i need a neat tidy way to tuck it away .

                                                                                                  Basically was just going to zig zag it up and down in a tidy bunch but would like to hear / see if any one has any better ideas .

                                                                                                  Again photo for attention

                                                                                                      Hey guys,

                                                                                                      I've lately started experiencing some overheating w my 74 CB750 k4. Not so much when I'm running on the freeway but more so if I ride through heavy traffic jam areas with constant start stops for over 30-45 mins. In which it will kill itself and refuse to start again until it cools down. I haven't done any form of engine mods and it is mechanically bone stock! Any thoughts on what I should start looking at? (Ps I've had the carb cleaned completely and replaced the floats recently) compression is as it should be too! All 4 cylinders fire as they should. Any pointers to consider would be much appreciated.

                                                                                                      Also another question: my throttle seems to open up a little more once it's warm. So I'm having to push fwd to close off a little. It almost feels like one of the push or pull cable starts loosening up if that makes sense. What would you suggest checking here?

                                                                                                      Thanks in advance
