Bikeman Performance Durability Piston Kit - BMP-P800DK-2
  • Custom designed taller pistons have less piston slap
  • Rings have been spaced apart for better cooling
  • Pistons have .020" wrist pin offset to take load off the intake side
  • Forged pistons are more durable and collapse less than factory pistons
  • Friction-resistant coated pistons
  • Lubrication holes in the skirt of the piston designed to lengthen piston skirt life
  • Gains 6-7 horsepower and even more for motors down on compression
  • A must-have for motors with over 1500 miles on stock pistons
  • Smoother running motor
  • No EFI controller required
  • Includes pistons, rings, circlips, wristpins, cylinder bolts, cylinder spacer, longer alignment pins and two base gaskets

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.
