Good To Know

Q: Does this set cover the entire engine? A: No, it covers the top end only, meaning the cylinder head and cylinder base areas. Bottom end seals and bearings are not included.

Q: Should I torque the head bolts in stages? A: Yes, follow the factory torque sequence and values for the 900 engine to avoid gasket damage or leaks. Recheck torque after the first heat cycle.
