I drag mine never had a problem out of it at all. It is streched 10 over and lowered 2, has an air shifter, 15 front and 49 rear vortex sprockets ( thought they wheelied before try that) and a shinko 003 ultra soft on the back. I´ve seen the big bore kits for them and was wondering if anyone has tried it and how it worked out. If that doesn´t sound good I´ll go with a punched out 1100XX blackbird motor and turbo. I don´t see why more people don´t drag them they´re damn fast and very light.
