Hello group, I have an f2 racebike and the fuel petcock is shot (vaccuum style) . Does anyone know of a motocross/non vacuum tap petcock that fits? I can certainly fit an OEM petcock but would prefer one without the vac fitting. Thank you!

 

The F3 petcock is non vacuum, gravity feed. Because the F3 was ram air and had a fuel pump. You can use the F3 petcock on the F2 but you should turn it to OFF when the bike is not running.
