This is on my 84 atc 200s. When I shut down the machine I can hear it keep spinning for a few seconds and doesn't sound good, like bearing noise. So I assume the bearing is gone. But another issue I'm having is when I'm coasting down a hill in 1st cause I have no brakes it seems to pick up speed as if it were in neutral. I have to give it a little shot then the compression will start slowing me down again. Which is kinda scary cause we ride in the rocky mountains.. would this issue be one way bearing or a clutch? The main clutch grabs hard and has never slipped.
