Hey i have an 02 cbr 600 F4i and at about 4 grand and up it vibrates really bad and the higher the rpm the worse it gets, and i dont have to be ridin down the road either it will do it just as bad sitting still, i can also hear some rattling noises comging from the valve cover i dont know if that could cause a vibration or not but it is making allot of noise it has plenty of oil in it and i have checked all the motor mount and bolts and they seem to be fine when i get done riding the vibration is so bad that my hands have gone numb after about 15 minutes of riding.i hope somebody has any sugestions.

 

I have heard of cam issues causing this but I am not sure.

 

did the vibration just start? did you just get the bike?
Some vibration is normal on a f4i,depending on how you ride it.The vibration can cause your hands to go to sleep(been there),also what bar ends are on it (this matters on the vobration also).

 

Yeah some more info will help. Compared to Vtwins, these bikes have little or no vibration. Since you said it vibrates at idle (not moving) it makes me thing the problem is pretty bad and not related to your drive train or tires/wheels.
