Good To Know

Q: Does this piston require cylinder boring? A: Yes, a .020 oversize piston needs the cylinder bored and honed to match the 81.50mm bore before assembly.

Q: Can I mix this with a standard bore piston? A: No, all cylinders in the engine should be sized consistently so compression stays balanced across the top end.

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