I am working on a co-worker's 2000 Polaris 250 Trailblazer quad. It needed a new starter or a starter rebuild. When I started working on it I discovered that it had no compression. Long story short, motor out, took it apart and it needs a piston, cylinder bore, crank bearing has a little side play but no up/down play.
Does anyone know what the best thing to do is? I can get the cylinder machined. Is it worth just buying a 1mm over piston/ring kit from wiseco ($80) and boring it 1mm over. Does the head need any work if you go to a piston overbore on these? Anyone know? It's a 2-stroke. I'm hoping to leave the crank bearing alone so as not to have to crack the cases.
Advice?
