I just picked up my third Banshee. It has a cool head (unknown domes) , FMF fattys, K&N filter, +5 timing. The guy I got it from said it was jetted right FMF calls for 260 mains on third notch, with no other mods. He never rejetted when he added the other mods. Plugs and white, hardly any smoke from the pipes. Bike runs HOT cant touch the head pipe after 1 minute. 1st question, should I run race gas to see if it runs cooler, 2nd What would be a good starting point for jetting? Anyway to tell what size domes?......Sorry for so many questions guys but the feedback I get from BHQ is always solid.
