The big end journals were all right, only some light marks that polished out. New std shells went in at rebuild time.
The metal from the cams and followers must have been cleaned out before i got the bike as it wasnt in the sludge that i cleaned out from the engine, the oil tank and oil pipes.
Apart from the main bushes, cams and followers the motor was in very good condition, std pistons and barrels with little wear, primary gears showing little wear. 10k miles on the clock, which is plausible knowing the bike's history.
Now fitted with morgo pump an inline oil filter.
