Cam chains don't last forever. They are a wearable part.
Can chain tennsioners don't last forever. They are a wearable part.
Self-adjusting camchain tensioners do not always self adjust.
So.
I would measure the camchain to see if it's worn out. There is usually a measurement in the manual for the maximum distance between a specified number of pins. If it is over this measurement, the camchain needs to be replaced.
I would remove and inspect the camchain tensioner blade to check it is not worn out, damaged (or in extreme cases, missing).
I would them re-fire the camchain tensioner and ensure it is correctly tensioning the chain.
I would then check the timing has not slipped before reassembling the bike.
If there is a significant amount of wear/damage to the tensioner blade, I would change the oil and clean the oil filter screen.
I'm not familiar with the CMX engine but if they are similar to the older CB250 motors, the CCT is a sort of sprung, curved plastic blade. On the CB250, it was in theory self-adjusting but the spring wasn't strong enough so you had to periodically loosen the adjuster nut, push down on top of the CCT with a screwdriver and re-tighten the nut. I've seen old superdream camchains chainsaw their way out through the barrel. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.
