Got ready to assemble crankcases and noticed the thread for the camchain tensioner was huge and mullered. How any PO could make it so bad?
Anyway, It appeared to be a (poor) 10mm x 1.5 thread so re-tapped and then made a suitable sleeve for the 6mm tensioner bolt. It feels secure, anyway

Of course, the tensioner thread is now little too short but as I'm about to make some new tensioner bolts, I'll make one a little longer. I'll make a small recess for an O-ring before it gets an application of Loctite.
Is there a reason the locking part of the tensioner is M8 - ie a larger thread?
