Specs At A Glance

Good To Know

Q: Does this kit require machine work on the cylinder? A: Because it is a standard 103mm bore piston, it is sized to fit the original cylinder diameter, though cylinder condition should be checked before installation. Q: Is a higher compression ratio harder on the engine? A: An 11:1 ratio increases combustion pressure, so quality fuel and correct jetting or tuning are recommended for reliable operation.

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