Vibration at 3,000-4,000 RPM
Hi, I just test rode 01' F4i with 11,000 miles and there are vibration at 3,000-4,000 RPM.
This vibration is pretty strong enough to make my hands itch. The vibration stops on higher RPM.
Is this normal or there are problem? & How much it will cost to fix it?
thanks,

RE: Vibration at 3,000-4,000 RPM
Not sure if there is a problem with the bike but I just put weighted bar ends on and I think they make a big difference in dampening the vibrations. Mine are almost 14 oz each and I know there was one even heaver than mine. I got the website from one of the posts on this site so do a little search for them. Good luck.

My opinion here:
Heavy bar ends are nice. They dampen the vibrations and if you get good one can act as sliders. But this is only masking the problem. The most common issue is wheel balancing. Make peace with a local shop owner and see if he can throw the tire on the balancer for ya (cheaper if you take the tire/rim off the bike yourself, unless you made hella peace). Chances are this will solve the problem. If not, then you may be looking at a few more serious things: Bent rim (which the mechanic would see while on the balancer), defective tire (too much of what is called road force), bent / loose steering parts, some goofy alignment problem, etc. Much more difficult to diagnose. Definitely start with the balance check though.
