Cam Chain Adjustment

A loose cam chain will cause the timing of the valve to change, resulting in poor engine performance. It will cause a drop in power output and also produce excessive noise.

  1. Adjustment is made by loosening the tensioner lock nut (2) and tensioner lock bolt (1) this will cause the tensioner push bar to automatically apply the proper tension to the chain.
  2. After completing the adjustment, tighten the lock nut.

NOTE: Do not apply additional pressure on the tension push bar as this will apply excessive tension to the chain and the guide rollers, shortening their service life.
