My 2004 Polaris Sportsman will only start when weather is warm. When I pull the start cord seems not much compression. I believe it will need a top end job. Where can I buy a cylinder, piston, rings, gasket kit and new drive belt that this forum would recommend? Thanks for the help. MTG

 

did you check the valve clearance first. if the valves are staying open then you won't have much compression either.
