ok heres what happened, riding home last night pretty chilly toolin home,about 50 degrees. crusin about 120mph saw a flash of light i was kind of in the zone and snapped out of it just when i saw it again, first i thought it was a cop but there was no one behind me, one more flash from behind i straightened up and let off the gas and got a couple low sounding back fires out the pipe. what the heck was it? just for background i have a 2001 busa, small airbox, full akrapovic, pcII, pair gone, tre on, dynoed, any ideas what i saw? was it just a little unburnt fuel flaming out the pipe? im confused the full akrapovic has only been on for about 9 days? i dont know. let me know thanks
