Surely some sort of slipper primary chain adjuster could be rigged up; ala Triumph unit twin.
Sorry If I've missed this suggestion on a previous post.

Hi all,
back on the road again since one month  :D
I'm very well pleased with the performance of the "new" gearbox.
Pic attached, thanks to all for your inputs!
Cheers,   Paul

Nice looking bike Paule, did you fit a slipper for primary chain?

Hi Graham, no, there was no need for a slipper/tensioner. I have adapted RH gearbox plate a bit more by grinding about 4 mm away. The C12 gearbox now has full way for adjusting primary chain.   Paul
