Good To Know

Q: Does this kit require modifications to the ATV wiring harness? A: No, this kit is engineered with OEM-style connectors to match the factory wiring harness. Always clean the harness plugs before snapping the new connectors together.

Q: Why is it important to replace the stator cover gasket? A: Reusing an old gasket can lead to engine oil leaks, which can lower your oil level and lead to stator overheating and premature failure.

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