K2,
As Cyclegod said.
I had one back in the day. Casing behind the impeller would rot out asap, resulting in the pump removing the oil and replacing it with water. Nice!!!!! H.A. said, "V can sell you a nuda case, oont it vill be the same in sex monts time"
If the case can be sorted - the bike was a dream. Handled and went like stink.
All the best
Pete
