Bike: 1996 fxsts. 44K miles. Zippers air filter open to atmosphere, and stock pipes.
Acts like it running out of fuel, does better at open throttle and acceleration but low end torque rpm it sputters. Had the same problem 2 weeks ago. Took apart petcock and cleaned it, didnt look too bad only a few varnish spots. took spring out and cut the diaphragm a little to make it a free flow petcock. Bike ran better but only 90 percent better. Was getting 48-50 mpg.
Got on last friday from work and it happened again, this time its lot worse. So i replaced hose from carb to petcock, cleaned the bowl out and the jet. Jet was not plugged. The problem still persists.
Im sure its a fuel delivery problem, is my float out of adjustment?
Any help would be appreciated.
