Vibration??

[Groomsy]

My 400EX is starting to concern me. I just got it back from the shop for its first maintnance and they had to replace a wiring harness. I noticed this before i took it to them, but anywho. When i get to the top end of every gear it feels like my motor is vibrating and it vibrates the whole bike. This quad has never been in a serious wreck so there is no chance that anything is bent.......Any suggestions or ideas of what it could be???:confused: :confused: :confused: :confused:

check and see if your axle is bent..a small bend can do that. it happened to me and there was a alot of vibration

do you have an aluminum skid plate? if so make sure it ain't vibrating on your frame......if that ain't it... start checking all the bolts on your bike starting with your head bolts:)
