43cc GIO F3...........Theres ways to make that 43cc just as powerful as a 49cc and rev even more........Welcome to the site
You need a dremel with assorted cutting bits.........43 and 49cc arent much different parts wise just cylinder size......Kool. I ordered a carbon reed already but I think I ordered for a 47. It needs to be faster I weigh 210lbs I've only got it between 15-18mph using a gps on my iPhone strapped to the hadle bar.
