Nice looking thing. What setup are you running ? Carb and jets? Crank etc? And what ignition?

[@10bobbit49]

Hi nice sound and great looking scooter, does it have a standard 3 speed box,

[@JamesDeVile]

Thanks! No, the engine is built from 4-speed PK parts and PKXL engine cases.

Top speed?

[@JamesDeVile]

Got it up to 69mph. That's plenty fast enough for me on 10" wheels!
