Motor started life as a Ts 250 1976 ... which is ideal for dropping a Rh 250 barrel onto
Oil pump is no longer required as I have drilled the LHS side casing to allow for bearing lubrication... 76 models have it cast in but not drilled
I have opened up the area were the pump was encased and re-braced it, filled in both tacho and pump drives holes.
Black pen marks show casting marks .... not cracks
