Sooo.. after sitting for a year, I dug the X1 out of the garage. No start. It had the same symtoms a few years (cranks over and occasionally runs for a second) and back then I replaced the fuel pump and regulator, all was good. Since it had the same symptoms this time, I replaced the pump and regulator again, but still the same symptoms. I haven't tested the pressure yet but when I remove the fuel line, fuel continually run out, instead of just a little, as it should. Bad regulator? | ||

woah up there pilgrim...not sure why you expect anything to fire up after sitting a year with maintainer on it or not...You are just throwin money at it blindly, and just got lucky with the reg and pump but probably because you fixed/changed somethin else involved...Doesn't sound like you are in the right mood to work on a bike thats givin you problems so let it go for the weekend,just think on it and eliminate some of the issues.I am not an injection expert at all but i know if the pump doesn't have the right amount of electricity its not goin to flow the right amount of gas to make the motor run right, and that could be a bad pump,BUT more than likely its just a bad ground and replacing the pump fixed that by luck.Make sure you have a fat ground strap on the bike and extras from starter to frame etc,they can do nothing but help.Always make sure that frame powder coating is ground off to get main neg cable connection 100%!.I have seen ground problems make an arc from clutch lever to perch ,no shit...ALWAYS use the KISS principle... | ||

Thanks. Same symtoms so it was highly possible that it was the same issue again. The original pump was a rusted mess and the coating on the wires were jelly like. This one looked fine on the outside.. I forgot to mention, I did a TPS reset also. Still though the constant fuel running out with the fuel line disconnected is not right. It should only drip a small amount and then quit, I do know that much. | ||

In case it helps anyone in the future ----- Yesterday I borrowed s fuel pressure tester from my LPS. Even though I could hear the fuel pump "whir" there was 0 pressures to the schrader valve. I took the fuel pump assembly back out of the tank and noticed that the pump orifice was not pushed very far into the assembly. I loosened th clamp, pushed the pump in more and re-tightened the clamp. Perfection! It cranks easily and runs like a champ now, I guess before the pump was pumping fuel but it was "escaping" before entering the regulator as it should.

Glad you found the problem and your bike is working now. And glad you posted the solution; it adds to the community knowledge. That is a weird one though, Alice. LOL Dave | ||

Awesome, I am having the same problem. I will pull my pump out and see if theres any funny businesss going on. | ||

A bit late to the party... but you can “rent” a fuel pressure gauge at any Advanced auto or O’reilly auto parts. You should have 49-50 psi with pump running and should hold when the pump turns off. If ok, check spark at both plugs (obviously with no open fuel). Remove a plug wire from the plug- take an old plug with the ground electrode cut off, put it on the end of the wire and ground the threaded section of the plug to the engine. Should have a bright arc across the plug. You need to know what you don’t have before replacing parts. |
