ABSTRACT:
A motorcycle engine having a tensioning mechanism for a cam chain. The mechanism includes a guide on the slack side of the chain which is controlled by two spaced pivotally-mounted links. One of the two links is biased by a spring to tension the cam chain. A sliding rod mechanism prevents facile motion of the links to lessen tension in the cam chain while allowing free tightening. The links are of such proportional extent that the end of the guide nearest the driving sprocket provides the tensioning motion while the end of the guide adjacent the driven sprocket remains tangent thereto.
