D1 Spec Crankcase Pressure Regulator

This crankcase pressure valve is build different from conventional reduced pressure Valves.
Blowback pressure discharged from crankcase is released back in to the airbox. But blocks it from coming in this way by using hydrodynamic vortex and inside pressure valve by setting the Reed Valve face to three faces, it is structured to distribute the force per face and discharge Blowback pressure even more.

1. Faster accelerator response
2. Reduction of breath feeling at the time of the accelerator stepping-back
3. Shift changes are smoother
6. Improvement of fuel consumption
