  • 2005 Polaris sportsman 90.
Polaris 90 sportsman would not start had only 50PSI of compression, ordered this kit quad now has 100 PSI of compression fires up on second kick now. So far impressed with the product. Will probably have to tune the carb do to more air flow now. The old piston is in the pictures.
