Those are great little bikes. A friend of mine has not long ago finished his shoestring of a rebuild and it's a little cracker!

The only thing that has let him down to date was the water pump O-ring that seals the pump (in the r/h casing) from the sump. It must've gone hard or brittle with old age and was letting water into the clutch/gearbox.

Good find!
