I have a fuel shutoff that leaks when in the off position on my 93 320. If it is not quite at the full off position its ok. My question is, is there any remedy for these much like the old Yamahas with the rubber disc that can be flipped over? i have yet to take it apart to see what the inner works are like and don't want it to leak in all positions as I am getting by now.

Thanks!

The rubber parts in your shut off are either old and brittle......or have been dissolved by ethanol in the fuel. Either way you will have to get new rubber parts if available seperately - or a new petcock assembly if the parts are not available.

I just just replaced the fuel petcock on my neighbors 2006 Honda CRF as it had set for about 6 months with ethanol blended fuel in the tank. It dissolved the rubber disc on the fuel shut off and corroded the aluminum base of the carb float needle and pushed the rubbertip crooked. It only took $ 60 in parts and 4 hours of labor to correct the problem......Hopefully he will remember to drain the fuel out of his bike before he stops riding it next winter.
