Won't start - no fuel from petcock
I bought a 2006 VTX1300C a month ago. I love it except it has been unreliable. Several times, including this morning it wouldn't start. I had to go by the used bike dealer I bought it from to pick up my new license plate so I rode my trustly 1983 Honda CX650C (that actually starts and runs) and mentioned the problem thinking they may have some help to offer. They tried to sell me a $10 tiny little bottle of magic potion that said I should pour in the tank. No thanks.
I bought a MityVac vacuum gauge/pump from Harbor Freight on the way home to test the vacuum to the petcock. (on sale for $29.99 for inside track members currently) Here is what I found:
Hooked vacuum pump to vacuum port on fuel valve. Pumped it up, and no pressure at all, not even momentarily. Not on "On", "Reserve", or "Off."
Unhooked vacuum hose from fuel valve, put gauge on that hose (from engine) and turned bike over. The needle "bounced" as I turned the bike over -- appearing to bounce up to 10+ in Hg (or maybe more, didn't read it exactly and it was bouncing apparently each revolution of the engine)
Disconnected fuel line from fuel valve, connected vacuum pump to vacuum port of fuel valve, and operated the pump. No fuel came out of the fuel valve.
This may be obvious so excuse the question. Does this mean I just need to buy the back half of the fuel valve that has the vacuum port on it and replace that half of it? I'm really frustrated because to me a bike is not just a toy but a mode of transportation. So far there have been several mornings that this bike has left me scrambling to crank up my old 1983 Honda and it's kind of irritating since I bought the VTX because my old CX is an antique and I thought I was getting a more reliable bike.
So far it hasn't left me stranded -- once it cranks and stays running it has been good. I just rode the bike yesterday about 40 miles, and then this morning -- nothing. When this happens, the bike never even floods, which is why I was suspecting it wasn't getting gas. The guys at the dealership said it was probably water in my gas or something. I told them I thought if there was something in the gas that at least the unspent gas would get sent out the exhaust (flooding) and I'd smell it. Then they said that it was probably that the petcock was gummed up to where none flowed through. I told them I doubted that it would run perfectly fine yesterday evening and suddenly gunk up to the point of not even trying to fire the next morning. Grrrr.
