Hi all finally got my nc29 back on the road and although goes well i have noticed a rattle exactly at 5000 revs you go past the 5k and it goes but there every time, anyone had this before, i have just had the bike set up on the dyno and its spot on, any help would be great,
Regards Phill

First the obvious - is anything loose? I had a vibration at about 8K on my GSX-R 600, thought the worst, kicking myself for buying a bike second hand, etc. Took it to the track and took the mirrors off, and when I put them back on the rattle was gone. It was a few fasteners loose on the screen that was causing the vibration.

been experiencing somethin like this meself, had the exhaust off just today and all but nothin was in there its gettin one me tits gonna take it to a pro, where does yours sound like its coming from

If it is a resonant rattle - comes and goes - then it surely is something loose and you just need to be methodical and check everything for tightness.

hi all, still trying to find this bleedin rattle change cans over and still there, so panels off next and track it that way,
Thanks again
Regards Phill

me too my mechanic seems to think its badly fit joints but the bikes whit him and he's having a look ill keep ya posted i dont have much hope hes the second one to look at it

hello mate , yep still got mine there 5000 to 5500 like a clock, i think it mat be the carbs somthing just rattling and they were just set up by a bike shop he said it could be exhaust headers blowing just a bit so going to look at that next,
good luck
regards Phill

you can sometimes get a rattle or resonance if you have stainless headers - dont ask me why - i recall reading it in another post.

mines not exactly at 5000 revs it just comes and goes at different revs but its very apparent when ya give a quick twist of the throttle from idle, it really does sound like something in the headers but theres nothing there. i do have the stainless headers so it could be that ill try dig that thread out if i can, is it fixable

well just got my bike back and the culprate has been found this lovely chunk of metal was inside the headers, the mechanic said its a balancer and woulda been tacked in there and it came loose he had t cut the header and re-weld it back up to get it out, the bike is spot on now :)
