hey guys ive got an Atomik Nitrous 140cc bigbore with 32 to 45mm exhaust, quick twist throttle, pro taper handle bars and uni air filter as well as a high rev cdi and now i want to change the sprockets on to achieve a higher top speed. it is really quick off the mark and i want to get it a bit faster in the top range. it currently has a 16 tooth sprocket on the front and a 42 tooth sprocket on the back. it is a start in any gear and what are my options thanx guys.
