Good To Know

Q: How do I know if my machine needs a top end rebuild? A: Common signs include low compression, hard starting, excessive oil consumption, and reduced power. A compression test and visual inspection of the cylinder will confirm whether a rebuild is needed.

Q: Should I replace the gaskets as well? A: Yes, new gaskets and seals are recommended whenever the top end is opened to prevent leaks. Check whether your kit includes them or if they must be ordered separately.

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