Fuel pump woes

RE: Fuel pump woes
Seems I'm having similar problems. Went ahead and pulled the pump off, went gravity feed only for a good long ride. About every 10 minutes the bike sputtered out, but I was usually able to restart it while still coasting. Guess that was the fuel consumption beating out the available fuel flow and the bowls drying out. Popping the cap seemed to help a little, but it was all pretty arbitrary and freakin hot out, so who knows. Anyone have experience in taking one of these pumps apart and maybe trying to fix it? Sure seems like all the manuals are very lacking in this department, and $100 would be nice to avoid on a new one.

RE: Fuel pump woes
You can bypass the fuel pump and go gravity feed only.The only setback of doing this is when you do high speed (trackdays,racing) long pulls in 5th or 6th gear the bike will shut off.But,you can get round that too by keeping the fuel tank 1/4 full.Normal street use and you probably won't notice the difference.

RE: Fuel pump woes
i just had the same problem, it was always random, bike would run great some days and others like ****, and every once in a while it would cut off doing 70mph or what ever speed. Finially two weeks ago i was about 30 miles from the house at about 1:00am mourning going home after a fun friday,and BOOM cut out and was not starting,
So i took off the fairing and removed the fuel pump by hand no tools, and hooked the main petcock fuel line straight to the carb and it started right up and it got me home, when i replaced the fuel pump the bike ran smoother, i think the pump was slowly failing, it runs awesome now no problems at all and it stopped popping so much when i get off the trottle. only a 100$ fix
