Diagrams are high enough and sharp! They guarantee both the low-end torque as the speed at high speeds, all provided with complete equipment (carburetion, exhaust ... see below).
The piston accompanying this cylinder is specifically designed bi segment model and adapted to the cylinder. It guarantees excellent strength with its 2 segments chrome purposes 1.2mm thickness for maximum torque and certain reductions in friction by the fineness of segments for high insured plans. Clearly, this high engine with this piston will cool no time with excellent settings needless to say, this is the perfect ratio torque / high speed.
