Howdy! A friend dropped off a 2010 800 rzr to look at with a starting problem. Click- buzz sort of crap. He put in a new battery. I tried jumping across the starter relay- nothing. So I take out both plugs and try. Cranks over perfect without the plugs in, plugs back in and it catches at TDC. So I thought the valves need adjustment but then I find out they have hydraulic lifters and can’t be adjusted. So now what? Sure would appreciate if someone could point me in the right direction. THX, have a good day!
