Hi all
My inner primary case was damaged by a wayward rear chain many years ago but never got rid of the case when I replaced it, but now I run a belt drive I cut the damaged part of the inner case behine the cluch housing cut out the whole slide seal as well the end of the inner case, I also cut 2 slots at the front of the inner case so fresh air can flow into the primary case, the good thing about this I can still run my outer primary case with out any holes in it, the only part of the belt you can see is where it runs around the cluch housing, but from the side of the bike it looks just like the standard primary.
I have been running with this for about 5 months now, the best part is you can see that the belt is running true at anytime its running and it seems the be keeping nice and cool insde, the only problem I through I mite have is the rear chain lub getting on the belt but so far no problems yet, very happy with this set up.
