45mm Lectron carbs, 1-5 override, bike was originally put together by Dan Hull at A&S, but has been gone through by my mechanic Tim Mills. This is a grudge bike so no times until you buy it. I got vids to serious buyers of it beating a 24mill twister, a 20mill twister, and a 18mill DM. I would rather race it than sell it but I can't get any races.
