Leaking petcock

Postby pshaginaw » Thu Oct 22, 2015 4:35 pm



The petcock on my '78 GL1000 leaked in the 'off' position. I removed the petcock, and it fortunately is the type that can be disassembled via two small screws. I took off the lever and found the inner gasket that allows selection of res-off-on had crumbled. Does anyone have a source for a replacement? I tried Sudco, no luck with rebuild kits. BikeBandit and Western Hills only sell the whole assembly. Can I use an O ring to prevent leaking and put a shutoff downstream? Can I get a 2.55mm hard rubber gasket and fabricate one? What have others done in such a situation?

good afternoon, I would not use rubber because of the ethanol in todays gas causes rubber to melt. Any auto part store has gasket material you can purchase and make your own gasket. :D :D

I was able to get replacement parts from Randakk. Looks like I was a victim of the Ethanol fiasco. Thanks for the help.

Better check your fuel lines and fuel filter while your in there but I know you did that already.

My petcock leaked a little when changing from off to on. I didn't find the out the decay from age and ethanol had plugged the reserve P/u until I switched it and failed 3 miles from a station in Kansas. My Friends were not real happy for the delay caused by circling back to find me out of gas. Oh well.. They fixed me up and and back road. Moral of the story: if its rubber replace it. The newer products from Randak are ethanol resistant.
