    APE cam chain tensioner

    I'm trading out the stock tensioner for the APE billet piece. I'm having trouble getting it adjusted correctly and the "instructions" are little help. I have an otherwise stock '82 1100.

    Can someone give me a measurement on how far the adjusting bolt should be out?

    much obliged!

      It isn't about how much bolt is sticking out. It is about removing the play from the cam chain. Ray.

          I basically went in until it stopped and backed it out 1/4 turn then locked it down. Just wanted to make sure I wasn't going to snap a cam chain when I got on it.

              On mine I just remove the sparkpugs and turn the motor over by hand while tighting the bolt until it stops by hand then lock the jam nut down.

                  That's exactly what I did. I just wanted to be sure I didn't clamp it down too tight.

                          I usually shove down on the chain between the two cams to take all the slack out.

                          Then I take the slack out by turning in the adjuster until I have only a little bit of up and down play in the chain between the cams. I also use one of those unbreakable cam chain guides. Good insurance. make sure the manual adjuster is fully seated in the notch on the guide.
