I just bought the $100 shipped Airsal 70cc kit, and a dellorto SHA 16/16 carb with intake and jets from 80-100. I've already got a tecno circuit, and will probably have the opportunity to try out other pipes. Anyone running this kit/carb setup? It seems that most peeps are running in the mid 80's with this kit and a midsize carb. Any problems I would run into when assembling a week? I know how to smooth out the ports, and the wiki says that they should be, but what would I do differently when working witht the nikasil lining? Does it chip easily? Use a different bit? Any help is appreciated. Joe
