So now he is on two minds, to try and fix the original cases or go for a new Pinasco 125/150cc cases.
I know this community is very resourceful so I'm relying on the experts to help us decide what to do next with his build.
Brief history, the bike was imported from Greece, and had a DR 177 on it with a Cosa clutch, everything else was stock.
The auto-lube failed causing the DR to hard seize.
