Re: CAN ANYONE HELP ME!! PLEASE?
Ok I need a couple questions answered ( Answers will most likely solve my problems!)
1: Is the fuel pump suppose to just assist the gravity feed in getting the fuel up to the carbs and thats it, or is it suppose to also put pressure into the carbs? I did try gravity feed from the tank but that didnt really help at all...(but I also had the airbox and velocity stacks and everything off when i tried it, it was just straight open carbs, but everything that attaches to them other then that were connected)
2: OK, HERE IS MY MAIN QUESTION: The fuel pump I got from a guy at a bike shop out in the middle of nowhere, he said he didn't have the fuel pump for my exact bike but he had another pump that was almost identical, except that it had a different connector/relay on the end of the two wires coming out of the fuel pump. He said it would work and that I should just splice the old pumps connector/relay onto the pump he sold me and it would work... so in actaulity this pump is the WRONG pump and could have come off a completly different bike( make/model ) as far as I know. Even though it works and is squirting fuel all the way up to the carbs and looks identical other then the connector/relay and the vent tube comes out the side instead of the bottom so instead of the two fuel pump ports laying horizontal, I had to run them vertical so that the vent tube would point downward. Could the pump still be the problem? Being that it is possibly not supplying the correct volume/ pressure for my bike? The guy almost seemed like he was just trying to make a sale, he said they didn't get much buisness out there so its possible... When the bike did quit running it bogged at around 4.5k and then 3k then it died and hasnt ran since, I found the fuel pump to not be working at all when it did die and all the symptoms pointed to that, and they kinda still do.... (keep in mind the pump i have on there now is the WRONG pump or at least the wrong connector/relay, and i spliced on the connector/relay off the old broken pump, but it is working and squirting gas and it does build a slight pressure when i plug the tube with my thumb) SO COULD IT BE supplying the wrong VOLUME/PRESSURE or not enough of ethier, or. So I could still have a fuel pump problem?
3: Could the air vent soleniod cause the bike to not run completly if it were to fail? (altho when i pour gas into the carbs and it starts, the pistons operate correctly) If you don't know what a AV SOL is, I described it in the following sentences...
The air vent SOL is what controls the air pressure which operates piston in the carb (the piston is also connected to the needle)... There are some air tubes runing from the direct air duct then runs into the AV SOL then into the carb, one side lifts up the carb piston with the needle and the other shoots a little gas out of what looks to be a jet or tube of some sort in the carb (when i blow on it, which is probably not it correct functioning anyway, but thats what happened :-) ). Oh and the air vent tubes are all clog free.....I went out tonight and tried to see if my pump was making pressure and it was, it doesnt feel like a whole lot of pressure. I could hold the fuel back with my thumb, maybe like a pound or two (PSI) Im not sure if the air vent SOL would cause a total failure and cause the bike not to run, but like I said im considering everything... If it was the pump not forcing enough gas through the carbs, it would make sense and fit the symptoms quite well, i was considering the air vent SOL as the another avenue. And with the pump thing, I wanted to be certain that it didnt just assist the gravity feed before I got buying a new one for 150 just to have that one not work after I already spent 75 on this ("WRONG") one.
