I got the old Commuter for free and it didn't run. But was all there so I tore apart the motor and threw the airsal 70cc kit with the gianelli pipe. It ran great with the stock sqaure bing but I wanted more power. Smaller rear gear so I had more in the top speed department. Then the 21mm carb with the correct intake manifold. the rips like crazy now. Pics will be up as soon as i have some good photos
