While riding home in the rain Friday, the engine just quit. I didn't sputter, so I'm not convinced it was wet ignition . I have taken off without turning on petcock before and engine started to die similarly. After tuning the fuel shut off from on to reserve a time or two I managed to get it firing on three cylinders and eventually all six. I'm thinking it's the shut off valve malfunctioning. Is this the right assumption or is there something else to look for? ???

I agree with you Raja,, your petcock may need a rebuild,, not too complicated a procedure. Do a search on petcock problems and you will find all kinds of information on doing it,, there is probably some articles about it in shoptalk,, check it out. Rebuild kits available on eBay, at Partzilla for OEM parts, and many other places. This is assuming you still have the stock petcock.

It's not the petcock I believe. It's you on off switch on the right side handle bar. You need to take it apart clean it good and put some dielectric grease over it. While your in there it would be a good time to do your starter switch as well.

:-\pancho, I do have a stock petcock. I will check it out to see if the vacuum holds. Big Mac: You are talking about the kill switch right?

If the rain was fairly heavy, the problem may be a 'drowned' fuel tank vent line. Up from the bottom of the line [near the swing arm] there should be a plastic ' T ' [ nothing attached to one nipple] which is there to act as a vacuum break. But, things happen and it could get plugged. So, in heavy rain the lower end may fill with water and not allow the tank to vent. The common fix is just cut off a bottom few inches from that line.
If the fuel tank has be off recently, then that line can/could be kinked upon re-installation not allowing the tank to vent.
Also, as said, the OEM petcock diaphragm could going bad.

Thanks Patrick.. It was raining heavy. I will check all these things. Somehow it was a fuel starvation that was momentary I believe ???.

After reading this again,, I would go with what Patrick suggested before the petcock,,, the circumstances were right for the vent line to be causing the problem.

:-\I just pulled the tank off and found nothing obvious to conclude . Tested the petcock, ok. Checked all vacuum lines too. Salami cut one inch off vent tube and hope the problem is resolved. Once again, thanks to all for your inputs. Fellow valkers are always a great resource. The girl is running fine again.
