another exhaust question

[Notch000]

Recently fitted a SP carbon can on my FZR, since fitting my bike had a developed a vibration around 4800-5500 RPM, not all the time and seems to be worse when hot,
 
the vib is felt most in the right foot peg, I cant really feel it thru the bar or anywhere near as bad on the LHS, i ve check the exhaust for leaks and also checked the cener stand is sitting snug on the new link pipe ?? the ped also apears solid with no loose fittings
 
Is something to do with the engine/carbs etc ??? do i need a tune or something ?? im pretty new to this all
My bike is also fitted with a 25kw restrictor

Have you tried putting the original exhaust back on and seeing if it still happens (ie, putting it back to a known standard).

Is it down on power, or hesitant on the throttle at all?

Some exhausts do need setting up / re-fuelling to get the best from them, and the restrictor being fitted might not help in this regard.

you also need to check if the new pipe is touching anywhere. especially after heat has expanded it slightly. it shouldnt touch anything at all. crawl underneath and have a look, preferably with the engine running, but watch out for any hot oil drips!

2 good suggestions above. can`t really add to them. good luck

cant see the exhasut touching anything.......
Also im waitign to refit the original, i looked but found it difficulity finding a replacement gasket then the one i got was the wrong size so, il let ye know what the outcome is.....
not down on power or hesitant at all either

What age / mileage is the bike?

Out of interest, is there any other mods to it?

Have you done a general bolt tightness check (ie, including screws that are unrelated to the exhaust itself)? to rule that out?

[Notch000]

bike is FZS 600, 1999, 47,000km
No other mods im aware of, il check out the bolts etc when it stops raining

Should all of the above fail and problem persists, be aware that resonance will be felt through the whole bike if the exhaust can is only single skinned no matter what you do.. Paricularly on the budget end of whats available.. Used to suffer sumthin rotten with viper race can on a previous Thundercat..

.....yes mate?..i was refering to that one!!...make sure you got it fitted correctly!...ie,if its the wrong way round it will alow the bolt to touch the mount and poss vibrate?

[CRH]

also what you could try?..is to remove end can!...try it without and see if vibes go??.... ...

that neighbours would love that lol, but seriously the only way to check results would be to go for a decent spin but  i live in a built up area
