To achieve higher revs you should consider a racing crankshaft. Beside the very good overall quality the timings of the inlet duration is longer. This gives a better cylinder filling and hence more power over the complete rev range. A good step not just for revvy engines.

Specially on engines with capacities of 130cc and more it gives great results. The rev range is noticeable broadened and the engines revs much higher.

The PK XL has a much more solid taper than the V50 crank. Therefore it is capable to sustain much higher forces. An additional feature is that it can be used with the ultra light flywheels for much improved acceleration and power output.
