Description
It is a long-stroke engine, bore x stroke is 16.27 x 16.80mm. It has quicker response in low range and more torque in middle range with consistent idling.
The new piston/liner is conventional 3-port type enabling more torque over the power range.
The new crankshaft has DLC coating as we always do for OS SPEED engines. The two tungsten counterweights are embedded in the crankshaft contributing consistent idling and quick rpm down according to throttle move.
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.
An o-ringed inner head, which absorbs vibration and prevents dust coming into the combustion chamber.
