Hey guys, I was wondering if anyone has tried the GasBike/KingsMotorBikes GT90 Conversion Kit... Is it any good? (..does it live up to it's claim of "up to 10 horsepower"?) Anyone know where to get the parts to complete it? ...I have a Grubee SkyHawk GT5... Could I take the crank, connecting rod, clutch, and misc hardware out of that to put the GT90 together? Thank guys!
