I Have a Firebolt xb12R 2005, I ride alot and just bought this firebolt about 3 months ago with 19,000 on it. tuned it up and it has been problem free. was out the other day and it had a slight mild sputter. just at random. Started it today and it ran ruff then back fired, ran a little more and back fired again. Then Died. I primed the pump again and it fired up idoled and then died again. Now it wont start unless I let it sit for 15+mins. Any Ideas? I want to ride and my Harley dealer takes forever to get me parts?
