The power transmission from the crankshaft to the
secondary shaft i s chain-driven, utilizing a Hy-Vo (high
velocity) chain. The Hy-Vo chain i s a rocker-joint type
with a pin and rocker construction. Some of the special
features o f the Hy-Vo chain are its capacity to transmit
much power at high speed, i t s resistance to heat seizure
due to a construction which employs rolling rather than
sliding friction, quiet operation even at high rpm, and
low power loss.
