Hi Johan, and hello to Finland, that's where you are, no? Welcome to the A forum, hope you will find help & info. Don't worry about the english details, if there is something not clear, we'll ask. If you have a picture, post it in bikes & pictures.
And by the way, I have some click-clack timing side, never really sorted out, and difficult to locate, wondered, among other things, if was too much side play in the camshaft, something with the breather etc. Not critical in my case, but always nice to get rid of mechanical noise.
Regards
Erling
