Description
Replace a broken, worn or missing fuel valve knob on your classic Yamaha two-stroke with the WSM Fuel Valve Knob. This direct-replacement knob restores smooth, positive ON/OFF/RESERVE operation to the factory fuel petcock, preventing fuel leaks, accidental shut-off or inability to switch tanks while riding.
Molded from durable, UV- and fuel-resistant plastic with the correct knurled grip and markings, it fits perfectly and looks factory fresh. A simple, inexpensive fix that makes a big difference on older Exciter, GP, WaveRunner and SuperJet models where the original knob has cracked or rounded off.
