Question, say I go on ebay and buy some cobra pipes and just stick them on my shadow without rejetting whats gonna happen? Will it mess up my motor? Will it not crank? What will happen?. Im not a mechanic and have rode hondas most of my riding life and since a honda just seems to never die I havent had to do to much work on any bike ive ever had to learn anything about working on a bike

  • don't have the experience of the other posters but when i replaced my factory pipes with cobra pipes thing sounded good but was hard to start and coughed and sputtered so bad but after new jet kit sounds great ride and enjoy

  • Bikes are like women "SOME DO SOME DON'T..............:)

  • and my other one

  • Larry Fitzsimmons said it right. Some need rejetting some don't. Mine didn't, so when people ask, that is what I tell them. You can work in a bike shop for 95 years for all I care. That doesn't change the fact that my bike didn't need rejetting.

  • Could turn exhausts blue, which would most likely be caused by heat due to lean gas/air mixture. Haven't experience this, just what I've read in past. A good set of V&H exhausts will decrease back pressure. Will also normally give 5% more power (if rejet done properly) while consuming about 10% more fuel. At least that's what V & Hines folks told me.

  • WELL SAID Danny Thornton...CAR,TRUCK,BIKE DOESNT MATTER,LESS BACK PRESSURE WILL CAUSE A LEAN CONDITION,PERIOD! WILL IT STILL RUN AND START,YEP.WILL IT EVENTUALY BURN A VALVE ,YEP. BUT HEY DROP 500.00 ON A NEW SET OF PIPES AND FORGET ABOUT SETTING IT UP PROPERLY AND LOOSING HORSPOWER (WHICH IS WHY MOST BUYERS GET THEM FOR) ....EVER WONDER "WHY" THE AFTERMARKEY EXHAUST COMPANYS OFFER A JETTING KIT WITH THERE PIPES???? BUT WHAT DO THOSE GUYS KNOW.

  • If the header pipes aren't of double wall construction, they may turn blue/gold no matter whet you do. Wear it like a badge of honor.

  • Don Nolen don't get your panties in a "WAD".Some of those guys weren't even shitting yellow while we were working on bikes.Come on man take a deep breathe and let it go............

  • IM DEF NOT..I HAVE WAY TO MANY OTHER THINGS GOING ON,AND I REALY WASNT ARGUING,JUST TRYING TO PASS SOME INFO..ITS ALL COOL ON MY END.
