Yesterday I took a trip with the bike. And when I passed 8k rev and up to 11k+ it started vibrating or something like that. I have done nothing with the bike except filling it up with petrol, it just happend. Maybe it's something with the power valve since it happens at the same time it opens..? But the pv is working and I don't think there is any power loss....

the best thing is to take you tank off and you side fairing and go round checking bolts reving at such high rmp will loosurn bolts that wernt 100% tight same as the little rc cars
Will probably do so tomorrow!

the whole bike vibrates?? it could be engine mounts, or it could be alot of other things.
if the mounts dont make a difference then check chain tightness,wheel bearings. if no luck then it could be a bearing inside the engine which then becomes exspensive

does it do it when you pass 8k in every gear? or only in top? if its in every gear its engine related and most likely a bearing, if only in top gear its most likely to do with the bike and id guess wheen balance or such

An update; Well, the bike is vibrating at most at about 9k rpm. But it's not a BIG kind of vibrating we're talking about...
Will check the engine mounts later.
After some time of thinking I can maybe think that I can imagining it, can't be sure...
