I have a Vinson 500 that was running fine, had a little bit of chatter when using rear brakes. Got stuck in the mud, and now it has chatter constantly. I need to know what I should look into or do....? Any advice is helpful.

 

so- maybe I'm not understanding correctly but... your atv is running fine, you had a little chatter from the rear brakes... you got stuck in the mud... and now you have a lot of chatter in the rear brakes?

If I'm understanding this correctly (and I may not be), it is in my professional opinion that you start your brake chatter diagnostic at the ...... drum-role please..................................... rear brakes.

either that, or the handlebar grip bearings might be worn out.

 

The chatter is no longer coming from the rear brakes. It's coming from inside the clutch housing/case. I assume, anyways. I looked at it today and found that my front u-joint is broken, and I'm ordering parts. But, the chatter inside the clutch casing still worries me. Seems like it's gotten worse.

 

Better inspect further.
