It sounds like a fuel starvation problem since it's spitting back out of the carb. Check you fuel cap to see if the vent is working. Loosen the cap and ride and see if that makes any difference.

Also, if your bike is equipped with the original vacuum equipped petcock, there could be problem with this as well. I've seen them get holes in the diaphragm and I've seen cause a vacuum leak. Check the vacuum hose and diaphragm. You'll have to remove the petcock from the tank. Personally, I'd recommend that you change the petcock to a high quality manually operated petcock like a Pingel.

Good Luck

2003 harley sportster runs fine for about 20 min then dies and wont start for about an hour the runs fine again for 20 min then dies


Almost sound like it is starving for good gas flow. The first thing I would check it the vacuum hose connected to it. It might be cracked. If it is good, I would check the screen on the petcock itself and for anything inside the gas tank that could cause blockage of the fuel flow.

Easy steps for replacing clutch lever? -Mark


Follow the clutch cable downward until you get to the rubber bellows that covers the clutch cable adjuster. Slide the bellows up or down to gain access to the adjuster. Loosen the lock nut and turn the adjuster inwards making the cable as short as possible.

Remove the pivot pin for the lever and rotate the lever forward. Positon the lever so that it will come off the cable end. Lubricate the cable end and replace the lever with the new one. Reposition the lever and install the pivot pin. Readjust the cable adjuster so that you have approximately 1/8" of free travel in the lever.

Good Luck

I would guess stale gasoline or fuel. Try fresh fuel in the tank. If this doesn't clear the problem, you could need to have your carburetor or fuel injection system cleaned. I'm not even sure if they put fuel injection on Sportsters since I don't work on fuel injected bikes. I mostly work on the older bikes like Panheads, Shovelheads, Evos. Not too many Sportsters but have worked on a lot of Ironhead Sportsters. Try the fuel first. It's a cheap fix. Hope it works for you. Good luck with the knee replacement. My wife had one knee replaced and it works great.

I would check both spark plugs then check the timing and if not fixed check the coil to see if it is bad.
