Increase your horsepower and torque with this big bore kit from BMP! We bore out your stock cylinders to 82mm, and send you on your way with a Cometic gasket kit. The extremely high quality forged Wossner pistons are available in a 10.5:1 pump gas compression ratio. This is an exchange cylinder program, however you may purchase the kit outright for only $400 extra!
Head porting, high performance cam, performance exhaust, power commander and clutching are recommended options. You can run the big bore cylinder on a 100% stock setup, but it will run a little on the lean side. Since dirt ingestion is the #1 cause of motor problems in the RZR 800, we recommend our high flow intake kit.
