Yep, all you need is a slightly larger jet. A 72cc JOG can use a jet as large as a #110, depending on altitude. My 50cc is using a #90 atm.

The 1e40 airbox is a great design, and does not need mods to accommodate a bigger main jet.

mine had a 68 and ran great stock where im at 2000 ft sea level so he is going to try a 75 first.im keeping the stock airbox cause everyone says they run fine with them and the minarelli doesn't like uni filters

A bigger carb would help the power but a bigger piston means more intake velocity, which means more air, usually a re-jet is a good way to go
