I had the twist throttle taken off my banshee and the thumb throttle put back on. (FOR THE REASON OF SENDING ME TO THE HOSPITAL BY AMBULANCE!) Afterwards the bike bogs in 1 st 2nd gear then comes alive in 3rd thru 6th + smokes really bad at 50.1 mixture (Belray). I had a local shop do the swap. The bike before ran excellent with no smoke!? Any thoughts would be apreciated! (The bike has fmf gold series pipes, boost bottle, and a alba kn intake.)
