Good To Know
Q: How do I know which position is on, off, and reserve? A: The lever markings correspond to the standard tank flow settings, with reserve drawing from the lower pickup inside the tank. Match the lever arrow to the desired position before riding.
Q: Will this petcock work on every YFM350 year listed? A: It is intended for the 1987-2004 Warrior 350 range, but Yamaha made small running changes over the years. Confirm the tank outlet and mounting pattern on 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.
