I have a 1983 Yamaha xv500 virago that has a gas leak! Ive properly destroyed the petcock and found out it is not made any more! I bought a used one from the junk dealer and it is the same leak! does any one know hoe to by pass the vachume petcock on this bike! or any ideas on how to fix it? I tried sealing the vacuum valve still leaks...
