Frequently Asked Questions
Q: When should I use a .020 oversize piston?
A: You should use this .020 oversize piston when your cylinder bore has been machined or honed to remove imperfections, scoring, or wear from previous heat cycles. It is designed to restore proper piston-to-wall clearance for optimal compression.
Q: Is this piston compatible with standard rings?
A: No, you must use rings specifically sized for a .020 oversize piston. Using standard rings will result in improper end-gap and poor engine performance.
Q: Why does this piston have a dished top?
A: The dished top profile is designed to manage combustion chamber pressure and help reduce the risk of detonation, ensuring a smoother powerband and more reliable performance under racing conditions.
Q: Do I need to hone my cylinder before installing this piston?
A: Yes. To ensure the new piston and rings seat correctly, the cylinder should be professionally honed to the correct diameter to match the .020 oversize specification.
Q: Can I use this in a stock 196cc engine?
A: This piston is intended for engines that have been bored out to accommodate the .020 oversize. It will not fit a standard, non-machined 196cc cylinder bore.
