Specs At A Glance

Good To Know

Q: Can I install this kit without machine work? A: A top end kit like this is typically fitted after the cylinder bore and piston clearance are verified. Check piston-to-cylinder clearance and ring end gap before assembly.

Q: Should I replace other parts while the top end is apart? A: Inspect the cam chain, valves, and seals while the engine is open. Replacing worn valvetrain parts at this stage saves a second teardown later.

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