not all sorted but running cvt and pull start best advice i loved my 66cc 2 stroke but throw it away this thing is so quiet and ridiculously fast like mental quick gps on phone said max speed 57 and im still playing with the set up out the box no vibration no noise massive torque compared to 66 need to adjust gearing as it will power wheelie i bought the engine from a kart company so it may not be 6.5 hp now as it has different carb cams exhaust and valves still i paid £120 for it with very few miles on it
