Question about 2004 Buell Firebolt XB12R
Most all bikes i"ve worked on have fuse protection. i"ve been on this site for awhile and have seen many questions about fuel pumps, but so far nobody has ever included in their diagnoses that there bike starts and runs fine. but i myself can see why.. because i ran into the same problem with my old cbr..it just wasnt running fine, seemed like a fuel issue so i turned the key on and tried to listen for a pump sound and found none, so i purchased a new pump, and installed it and turned the key and was so happy to hear the pump sound, fixed right! no, i turned it off and tried it again and then no sound, and in my mind im saying oh no! i just burnt up a new pump, but i said i"ll find out for sure so i took the old pump and reinstalled it (minus all the fuel that was left in it when i dumped it out)... and i turned the key on and voila! i heard the noise and now knew that i wasted $75 bucks! But, oh well, i got a spare now..i talked to another mechanic friend of mine about this problem and he been working on bike for over 40 years and he said you'll know if you have a fuel pump problem if you start to loose power in the upper rpm ranges... it"ll demand more fuel then its getting..so when the fuel pressure is correct i'm guessing that the fuel pump doesnt need the prime on all the time. but just to appease myself, i took the fuel pump hose off the fuel filter that was from the pump and ran it to a gas can and i started the bike and saw and felt the fuel squirtting out of the pump...but then i still had to correct the hesitation problem, so i heard about this Sea Foam cleaner stuff that can be purchased from Autozone $10 a can, pour in 1/3 can to 2 gallons fuel..bike was hard to start but would always push start.. so i got it started and ran it for about 11 miles before the stuff had eatin away at whatever was clogging up my carbs and it worked ever since then..so you might want to give this a try.
can you rate my answer, thanks!
