I was wondering if anyone else out there has had a problem with the fuel petcock internal rubber grommet falling apart and finding part of itself lodged between the fuel inlet and float needle valve? Today, I was riding and noticed fuel pouring from the overflow tube. I pull over, turned of the petcock, and it still continued to spill out. I called a friend of mine to come pick me and my bike up, and after getting home, I took the carb off, knowing the needle valve was obviously stuck wide open for some reason. What I found was a small piece of rubber, lodged between the needle valve and it's seat. That seemed odd, and also since the petcock would not turn off, I thought something was up. I took off the petcock, and the rubber flow control grommet had a chunk missing from it! Aha! That chunk was what caused the problem. I will be ordering a new petcock this week, since Honda doesn't offer just the rubber part (that sux). Anyway, has anyone had this happen before? it's new to me. I've had O-rings in the petcock fail and leak from the petcock itself (in previous bikes I've had), but never something like this. I guess it was just a faulty part to begin with. Kinda sucks, because this break-down forced me to ride my old '83 Suzuki DR500 for the rest of the evening, and it's not exactly "state of the art". L.L.
