The fuel of choice is Methanol, also referred to as Wood Alcohol or Methyl Alcohol, a highly poisonous, colourless liquid which is less volatile than petrol. Although carburettor jet sizes have to be significantly increased to cope with this fuel, it has one main advantage over petrol. Methanol burns at a much lower temperature compared to petrol. The original engine oil coolers can be removed and much smaller radiators can be employed, typically off of a 350cc road bike. Thus reducing overall weight.
All gearboxes are the standard factory designed and built units.
But the sport tends to use 2nd and 3rd gear only. 1st removed, which acts as neutral. Gear change is mainly achieved by either a foot activated system or a trigger next to the clutch lever. We use a pneumatic operated gearbox where the gears are changed by mean of compressed air, operated by a button on the handle bars. This technology has been borrowed from drag-racing where gear changes can be made without the need for shutting down the throttle.
