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 — Honda CB750 Four 69-78 Australia

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 — Honda CB750 Four 69-78 Australia

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.

G day all — Honda CB750 Four 69-78 Australia

G'day all

I am rebuilding my K2 motor.

Aparently it has CB350 pistons with a 64mm bore which makes it 800cc.

My problem is finding a head gasket any thoughts.

Or do I bite the bullet and bore out to 836kit.

CB750 Cafe — Honda CB750 Four 69-78 Australia

This is not mine, I am just reposting for him. Contact me if interested and I will put you in touch with him as I can't tag him in this post.

------------------------------- --------

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.

This is not mine, I am just reposting for him. Contact me if interested and I will put you in touch with him as I can't tag him in this post.

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?

So someone went on this little rampage saying things to upset people and posting sexualised content, called you all fools and squares and then he left the group. I can't understand what he was thinking but he obviously he wasn't thinking straight.

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.
