How do you tighten up a chain on a 185 Honda 3 wheeler?

This is how you tighten a loose cam chain. On the Honda 185s three wheelers there is a cam chain tensioner on the motor. First you need a 14mm wrench and a 10mm wrench and a screw with a fine thread now to get started you take the rubber boot off. Then you take the 10mm bolt off you put the fine thread screw in the hole. Then you start the motor up and loosin the 14mm locking nut while you do that you push down and lift up on the screw but hold the screw up and then tighten the locking nut and you should have the cam chain tightened.
