Good To Know

Q: Will this kit work with a standard bore cylinder? A: No, this kit is designed for a cylinder that has been bored .060 over the standard 87.0mm bore; your cylinder must be machined to 87.5mm.

Q: Are the gaskets reusable? A: No, all gaskets should be replaced with new ones during a top-end rebuild to ensure proper sealing and compression.

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