Cossi Posted September 6, 2005 Share Posted September 6, 2005 I have noticed a fairly large increase in vibration when I hit 5K rpm. It happens in all gears, and happens at whatever speed, it is consistent at 5K RPM. The only thing I haven't thought to do, is rev it to 5K in neutral. I am not sure if this has always been this way or has really come about recently. It is enough to notice the change in vibration but it isn't like it is going to come apart. Is this normal, or do I need to check a few things? Quote Link to comment Share on other sites More sharing options...
bonox Posted September 7, 2005 Share Posted September 7, 2005 it's either normal or your balance shafts may have moved a little. the way i adjust mine, i get more vibration at about 3000 and then up around 7000 - keep in mind everything is relative, and the bird is still HEAPS better than my zx9 alternatively, go through the whole bike - check throttle body synch, chain and sprockets, balance shafts etc. Quote Link to comment Share on other sites More sharing options...
86gn Posted September 7, 2005 Share Posted September 7, 2005 Some notice a vibration in that range when the CCT lifter starts to go bad. Quote Link to comment Share on other sites More sharing options...
Obby Posted September 7, 2005 Share Posted September 7, 2005 Take a good look at your chain. Maybe it's kinked or too tight/loose. That's what's causing my vibes right now. Quote Link to comment Share on other sites More sharing options...
Cossi Posted September 8, 2005 Author Share Posted September 8, 2005 I don't understand how the chain would cause a vibration at the same RPM in every gear. The chain is rotating at a completely different speed than the engine. Quote Link to comment Share on other sites More sharing options...

It happens mostly when I'm driving easy, with little stress on it on the freeway. Quote Link to comment Share on other sites More sharing options...
