Hi: My 2004 Harley will only run when leaving choke on, as soon as I push in choke the bike shuts down, also backfires when giving it gas when choke is still on, do you have any ideas what maybe causing this problem. Thanks Jerry

Sat up too long pull the carb bowl remove the jets clean and reinstall them pull your petcock off clean the screen put in good gas,and you should be set when you turn the gas on if the bowl vent leaks gas tap the carb bowl the float needle will find its seat and run

First question I would have to ask is this: Is the bike carberated or fuel injected. Has the bike been sitting, honestly from my experience I think you have an intake leak. You can check this by spraying a little starting fluid on the on the intake manifold flanges while the bike is running if the RPMs change up or down you have an intake leak.Spray the starting fluid from the air cleaner side and try not to get it in the back of the air cleaner. It only takes a little. Good Luck
