I have 2 tanks and 2 petcocks for my one bike. I recently got it working after not hearing it run since 2002. I had to service the petcock, as it leaked in the off position. After discovering I had a Brain space this morning (found the new seal in the unit not mounted on the bike), I set about on the 3rd time trying to stop this leak in the off position.No matter what i do, the new seal leaks in the off position on either petcock. I even refaced the levers to perfection. I thought I had it licked since it sat out in the sun for 3 or 4 hours with no fuel coming out of the bowl overflow pipes underneath, but after I parked it inside and went out several hours later, it was leaking. I'm at a loss, and more or less wanting a new petcock, but not finding any in the usual places. I am going to try another new seal, but the one I have is brand new and just doesn't look bad on either side. This little bike is all there, only the exhaust is not original, but it works fine (unrecognized 4 into 1), and it's performance is just what it should be. I only need to replace the carb gaskets and o-rings, they are just worn out, and freshen the top-end since it's leaking oil. As rare as these are, i'm just gonna hang on to it. Err I digress further, if some one has experienced a leaker in the off position and how they stopped it, or if anyone wants to sell me a known good petcock, I'm all ears!
