Both 1st and 2nd piston rings are of keystone type, a nd an expander ri ng is with the 2nd ri ng.
The keystone ri ng is less sticking and has excellent durability. The expander ring absorbs the
noise generated by the piston sl iding against the cylinder wall by means of its spring tensi on,
thus reduci ng overall noise.

Automatic centrifugal shoe type clutches are secured to the crankshaft and counter shaft. These
clutches have simple construction. When the clutch drive shoes, wh ich are thrown apart by cen­
trifugal force varying with the cran kshaft speed, come in contact with the clutch driven wheel,
engine power is transm itted to the counter shaft. When the engine speed fal ls, the centrifugal force
decreases and the drive shoes comes close together, thus separating from the driven whee l . This
eliminates the flow of engine power.
