Bikeman Performance has developed a Durability Kit for the Polaris 800 CFI twin engines of model years 2008-2014. According to Bikeman, the relatively short connecting rods and pistons have been the cause of the short life of the stock pistons and rings. Most machines will lose 20-30 pounds of compression after just 1,500 miles of riding, which causes a loss in performance.

How many miles do you have on your sled? If it has 1,500 miles or more, you’re in need of this kit. The key to this kit is the taller pistons developed by Bikeman which allow less piston rocking within the cylinders. This reduces the stress on the piston and rings dramatically. Bikeman also extends piston life by slightly changing the ring location, adding lubrication holes on all four corners of the piston, and Teflon coating the skirts. The Durability Kit also includes a cylinder spacer, but port timing isn’t changed because the piston is taller by the same amount as the cylinder is raised. The cool part about this is due to the added crankcase volume, Bikeman tells us the kit will produce about 6 more horsepower! 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, machined cylinder spacers, longer dowel pins, and two base gaskets. Fuel mods, you ask? Bikeman tells us this kit works with no extra EFI Controller. Priced at $499.95 order # BMP-P800DK from Bikeman Performance (www.BikemanPerformance.com) or call them at 715-483-3003.
