Specs At A Glance

Good To Know

Q: Do these fit both exhaust valves on my sled? A: This set is intended for the exhaust valve assembly, so confirm the quantity you need for your specific 800 engine before ordering. Q: Should I replace gaskets every time I service the valves? A: Replacing exhaust valve gaskets during service is good practice since old seals can harden and leak after removal.

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