head meph 12   85640 T   venturi alu   carb mephisto12
New head, redesigned to improve the flow of air and thus increase cooling and ensuring an optimal center of gravity.
The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by three inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. The durability has been significantly improved with the DLC coating..
This alloy venturi is specially shaped to minimize the boundry layer build up. With this special shape it will maximize the potential performance out put of your engine.
The shifted carburetor grants a better mixture flow inside through the crankcase intake. This gives the engine an improved fuel efficiency and a better power curve.
08677 18   28609 1   12601   16605
This piston/sleeve set is optimized for use in the competition events and is made from hard chromed brass and features 3 transfer ports.
  Combustion chamber:
The combustion chamber is supported by an o-ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
  Back plate:
The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod.
  Rear ball bearing:
The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
