This past weekend I too the rzr out for a ride around the neighborhood and started hearing a knocking noise and lost some power. I called a friend and he picked me up with his trailer. Looked at the clutch and there was a huge crack on it so figured it was the clutch. Just got the clutch puller yesterday and pulled the clutch off and the knocking is internal so I'm thinking it's a rod. This sucks. I've only had this rzr for about 3 months and it's been nothing but problems. So now I need to tear it down and see exactly what has happened to it. If it's a rod is there any recommendations on what crank to get or if there is a stroker crank is it worth getting?
