The width of the sealing surface on the rotary valve cheek is 17mm wide as on the original shaft.
The extended intake control angle results in a larger time cross section and thus enables a significant increase in power over the entire speed band.
The intake slot in the engine housing should be machined only on the side facing the rear wheel if necessary. Otherwise the intake port will be too late and the engine will spit back out of the intake.
Very nice stable shaft which provides more bandwidth in every engine.
