Check tensioner horseshoe for free movement and tensioner lock bolt ans plunger

The tensioner horseshoe is seized so thats being replaced. The tensioner lock bolt and plunger need repairing, I'm taking the crankcase today to see if it can be repaired as I'm not confident that I could drill and tap the new thread.

I'd replace the camchain as well.
As Bryn says, unlikely shells need changing. Check if the cylinder bore look OK and if there is a lip at the top.

Is there a list of the bolts required? I was trying to find a crankcase set so I know I've got the correct bolts. Westfield fasteners just seem to do individual and I dont want to get the wrong bolts :D

There is a fix for the adjuster that has an O ring fitted its a SS unit that requires the original thread to be tapped out.
It is similar to this one - my old purchase supplier is no longer listed mine was about £25.00

I've got the replacement one where you need to tap out the original thread. But it looks like the previous owner did such a bodge job it cant just be tapped out. It looks like the original thread is there and someone has tried to drill it at an angle.
