We have updated the porting in the 2018 version which gives a better power curve and even more torque.

This engine is easy starting, runs cool, simple to tune and requires only regular unleaded fuel.

You can also run it on mineral oil if it better suits your budget.

This winning combination is right a home in track events, all out bashing and its no slouch in the dunes either.
