Leaving the ten. mounted in the head, remove the center big bolt (slowly).
There is a spring right behind the bolt, so make sure to catch it as you remove the bolt.
Remove the spring. Take a small center punch that will fit in side the bolt hole (center punch should have a flat piont on it). The center punch should touch the end of the pluger in the ten. Take a small hammer and tap on the end of the punch. If the pluger is frozen this should knock it loose and tighten the chain.
Replace the spring and bolt and start the bike and check for noise.
Many thanks for the info Kurt, I have checked and the tensioner is working as it should, the balance chain also seems to be ok, bike has only done 11k miles and has a sweet engine , just want to keep it that way !!
