I picked up an '81 XS and having an issue with the petcock. It's leaking from the back side of the body where the spacer and diaphram for the vacuum line are. I put in a new gasket kit and have the spacer in (I believe) the correct way. Yet the fuel still seeps through and drips down the fuel line when the valve is in the 'run' postion. If I put it on either 'res' or 'prime', it pours out even more. I'm almost ready the throw in the towel and weld up the holes and install a traditional fuel shut-off petcock, but I really want to get this bike on the road and I have limited funds. Any input would be great.
