For a while now my 400ex has had a disconcerting vibration that I can't find the cause of. I've check all the bolts--nothing loose. In nuetral if I rev it up, it vibrates enough to feel it through the handlebars, in gear it's not so noticable.
Please help, is this normal, anyone else have this problem?

Yeh mostly all 400ex's vibrate. I put aluminum bars on and you can't feel it as much!

Its normal.
Vibration is normal... The only time you should be worried about it is if it is rattling mount bolts out, or if it is breaking the mounts completly
80 horsepower engines on 300 pound frames... Thats like having 2000 horsepower in your family car.

I got me some of those handle bar ends for street bikes, and it cut the vibration you feel in the handle bars in half.
