Ascot, Did you READ his post #1??
Your answers are all over the place. Wonder how you can be taken seriously.



Fortunately, I'm not chasing the White Rabbit. I seem to be on the lookout for the elusive Black Swan Event.

But, back to the regular scheduled programming, the debris is supposed to stay in the petcock bowl. Hodaka petcocks are much simpler designed and leak like crazy. The Yamaha petcock attempted to incorporate a shut off valve with a debris catcher. At $60 or more to rebuild, many have chosen the China knockoff that has the bullet screens.

Sorry to go off on a tangent, but does anyone have an inexpensive source for the bowl gasket on on the Chinese petcocks?

Rick C, thank you for the filter. After riding a bit I noticed gas leaking from the bowl of the petcock. I must have a tiny pinhole, cannot see with eye, have not tried with enhancement. My question is, how to plug a miniscual hole in bowl? Some abc gum might do the trick.

My first thought is that there is something amiss with the seal between the bowl and the body of the petcock. Either the seal or how the screen is fitting in there. I've had a leak like that, and it was very slow, appearing as a lone drip every now and then from the bottom of the bowl. Have you installed new rubber parts in the petcock? That's what took care of mine. Cleaned it in carb cleaner and then rebuilt it with new parts. You might just take it apart and clean it, and then reassemble it. Or just screw the bowl off (close the petcock lever; you knew that, right?) and re-seat and reassemble. [Why do I suddenly feel like RT325?]

Keep playing, my guess it’s something in the rubber like you said. Could have sworn it was dripping from the bottom. Replaced gasket between bowl and body with an oring, could not locate OEM gasket. O ring has worked for a bit. I’ll clean and reevaluate. Ty

If you shut it off, drain the bowl, put it back together, dust the outside good with baby powder, and turn it back on... the baby powder works well at helping see where the leak is coming from...

Works really good with oil seepage.
