Power band on a 2 stroke
In a typical two-stroke engine, the powerband is a narrow and high-RPM range, usually located in the upper part of the RPM scale. When a dirt bike reaches the powerband, …C m = 0.166 x L x N. Where: C m is mean piston speed, in feet per minute. L is stroke, in inches. N is crankshaft speed, in revolutions per minute. Thus, using again the Kawasaki F-5 engine as an example, with L being 2.68-inches and N given as 9000, we find that. Cm = 0.166 x 2.68 x 9000. Cm = 4000 ft/min.

Because burning takes place with each revolt of the crankshaft with a 2-stroke, this set-up puts out more control than a 4-stroke engine and the power has more prompt transfer. …
You will probably have to rebuild the top-end more often on a 2 stroke than a 4 stroke. However, there’s no valves that you have to check periodically on a 2 stroke. For example, you might get 150 hours of trail riding on a 2 stroke top end, but a 4 stroke ridden the same way might get 250-300 hours before needing a rebuild.

It controls the exhaust port size or height in relation to the engine RPMs. The 2 stroke power valve is fully open on the left and fully closed on the right.
