The thrust plate with surface treatment embedded in the cover plate reduces friction against a connecting rod to extend its life.
The boost port and the exhaust port of the crankcase are redesigned for optimum air flow.
The carburetor is trustable 22E type, which we have been using for B2103 Type R.
The cooling head is conventional round-shape type with standard height.
