How do you adjust CT110 cam chain?

To adjust the cam chain on a ct110 there is a little locknut and screw on the left hand side below the gear lever, it looks the same as the clutch adjuster on the opposite side. to adjust have the engine at idle at normal operating temperature then to adjust cam simply loosen the locknut then loosen the center bolt with your screw driver and tighten back up. this allows an automatic spring inside to retention the chain. if the chain still sound noisy to you then it made need to have the actual spring tightened up. it is a very simple task and you cannot break anything in doing so. on the bottom next to the sump plug there is another plug with an 14mm head, undo it and inside there will be a screw, just screw that up , it doesn't matter how far but i usually do it up all the way just to be safe. put the plug back on and loosen the adjuster nut and repeat above.
