Hi Jim,
was reading your advice above. I have recently purchased a 650 Dragstar Classic (V Twin), it has a bit of a rattle about the engine, I suspect one of the the cam chains / tensioners. Bike has low miles 3500 but had been stood quite a while.
Can I manually adjust the tensioners as you have described? I have a manual of sorts and the tensioner certainly looks as you have described (spring and ratchet etc).
Cheers
Richie
