ABSTRACT:
A tool for measuring movement of a strand of a chain extending between sprockets in a direction substantially transverse to the length of the strand, for example a primary motorcycle chain extending between a clutch sprocket and an engine compensating sprocket, wherein the movement of the chain needs to be adjusted at intervals, includes a handle section by which the tool is held and manipulated by a user. A chain engaging section is joined to the handle by an indicator section so that a user holding the handle can manipulate the chain engaging section to engage the strand of chain whose movement is to be measured. Movement of the tool will then move the chain. Indicia on the indicator section is usable to determine the movement of the chain. The tool can also be used to measure the tension of a belt or other material.
