Specs At A Glance

Good To Know

Q: Does this kit fit a stock, unbored cylinder? A: No, a .040 oversize piston requires the cylinder to be bored and honed to match the larger diameter first, so machine work is required before installation.

Q: Will I need to rejet the carburetor after installing this piston kit? A: Any change in bore and compression can affect fueling, so it is a good idea to check jetting and plug readings once the rebuilt engine is running.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
