G'day Bikerboy.
The pic at the top is my plunger.
The plunger mainshaft goes straight in a swingarm box. Chain adjustment would be as the s/a. The whole engine sprocket and cush need to be swaped to the plunger type. Then the whole plunger clutch will work.
The only part I don't know is if the sliding plate will seal.
Cheers

Cheers Muskrat

Looks like I need to think of a slipper type chain adjuster to fit in a swinging arm chaincase then  *smile*

When I get some time I will investigate this further
