Bikeman Performance Engine Durability Kit - BMP-P800DK
  • The relatively short rods and pistons have been the cause of the short life of the stock piston and rings
  • Most machines will lose 20-30 lbs. of compression after just 1500 miles of riding which causes loss in performance
  • If your sled has 1500 miles or more, you are in need of this kit!
  • The key to this kit is the taller pistons we developed which allow less piston rock
  • This reduces the stress on the piston and rings dramatically
  • We also extended piston life by slightly changing the ring location, adding lubrication holes on all four corners of the piston, and Teflon coated the skirts
  • The Durability kit includes a cylinder spacer, but port timing is not changed because the piston is taller by the same amount as the cylinder is raised
  • The added crankcase volume even produces 6 more horsepower
  • So your engine life is extended dramatically, and you gain power at the same time
  • The kit comes with two new Teflon coated pistons, rings, wristpins, circlips, longer cylinder bolts, our machined spacer, longer dowel pins, and two base gaskets
  • 6hp gain with no EFI Controller

NOTE:  We recommend turning up your oil pump 1 turn on non HO(Axys) motors.  On all models, we recommend pre-mixing your fuel at 100:1 in the tank when possible. This helps provide extra lubrication on the intake side of the piston.  Since the injector sprays that side of the pistons, the fuel washes the oil off. For this reason, adding extra lubrication with the fuel will also help extend piston life.

(2) Pistons
(2) Piston pins
(4) Circlips
(4) Rings
(1) Steel cylinder spacer
(2) Metal base gaskets
(2) Dowel pins

High quality product and as easy to install as claimed. Stock pistons had etching and rough spots after a 1000 miles. Was a used sled but a little comfort added to next season. I would definitely do it again no matter what polaris dealer said!

Better pistons.
The wossner Pistons in this kit are much better than the Pistons in some of the other kits.
