wierd vibration sound????

7 posts in this topic

I have a weird vibration sound only at high rpm's. It also seems like it happens when there is a very little load on the bike (ie. down hill, jumps, 2-3rd gear-ish). I've looked all over the bike and cant figure out what it is??? Any suggestions??? It doesn't sound like something is rattlting or breaking.... Just a vibration????

Have you checked all of you motor mount bolts; head stay, swingarm pivot, front bracket, and lower frame bolts?

did u recently put a skid plate on it? my brother put one on his crf450R and it had a weird vidration noise, only at certain engine RPMS thought. we had to put thin strips of rubber to isolate it and keep it from vibrating
