Question about 2008 Buell Firebolt XB12R
Riding along and bike stopped, after cooling off bike ran again but weak, now left overnight cranked and ran perfect then sputtered and stopped. Put fuel in thinking it was empty after first shutdown at the time it did not help, thought it was a system priming issue at first but now maybe you can help.
