Hello,
Well I just finished a 1 1/2 year project for my nephew. It is a 2004 90cc polaris sportsman. It died awhile ago with no compression any longer. My brother in law took it into the dealer and they told him it wasn’t worth fixing. So of coarse it gets dropped off at my garage. So I put a new piston,cylinder,head,and rings. I coated all parts with oil before assembly, have piston arrow towards exhaust, and torqued head down to 14 foot lbs. It actually started right up to my surprise . I kept the rpms nice and low and road it around my yard nice and easy for about 8 min then it just died. Motor appeared to freeze up. I felt much resistance as I gingerly kicked it over just once. I new enough just to let it sit and cool down. After 30 min it started right up and sounded fine so I shut it off immediately and that’s where I am now before I screw it up any worse. Any thoughts? It was smoking good like a 2 stroke should and the oil I used was from auto parts store. I dont know where I could of went wrong?
