I just replaced my belt on my 08 rzr 800 and went through a suggested break-in of running threw the all gears up and down through rpm range for 15 min then a 15 min break then repeated the process.

On my first ride on it after that I went out for a country cruise got it up to 45-50 mph in the course of a mile and a half or so then came to a stop sign. When I tried to go again nothing. It wouldn’t go forward in high or low. It would go into reverse but moved very slow in a very high rpm range. I then tried low again nothing. Then high nothing. Back to reverse same result as before. Then tried high again and it took off. Any ideas on what could cause this? Is my clutch screwed up?
