Common questions
What's included in this piston kit?
This kit includes the forged pistons, precision-fit piston rings, and wrist pins. Gasket kits are sold separately and are necessary for a complete engine rebuild.
Do these pistons require any cylinder machining?
Yes, this kit is designed for a +.020 inch oversized bore, meaning your cylinders will need to be bored and honed to this exact specification for proper fitment and performance.
Will my motorcycle require a custom tune after installation?
Absolutely. Upgrading to a 10.5:1 compression ratio requires a professional dyno tune to optimize your engine's fuel maps and ignition timing, preventing damage and maximizing performance.
