Good To Know

Q: How do I know if my petcock needs replacing? A: Common signs include fuel leaking around the tank fitting, a lever that will not turn, or the engine running lean at high speed. Replacing the petcock restores proper fuel control.

Q: Does this petcock come with mounting hardware? A: Mounting screws are not always included, so reuse the original hardware if it is in good condition. Confirm the fitment matches your machine before ordering.

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