beng said:J.A.W. said:. The oiling to the rocker arms was supplied by nice hot oil from the return to the oil tank.
beng said:It was Norton's first 650 and was right on the leading edge of their development program. Some good mechanics think that the oiling system on the Commandos is marginal, well here you have basically the same engine and power level with the oil pump running at half-speed and utilizing much smaller oil passageways! Which is why I have quite a few sets of 1961 & 1962 Norton 650cc crankcases laying around here with weld repairs and scars from where rods let go in them. The oiling to the rocker arms was supplied by nice hot oil from the return to the oil tank.

Rohan said:Just for the record, the 1961/62 Norton Parts Book PS 214 lists the speedo page 48 for BOTH the 650 Std AND the 650 Deluxe as being the 150 mph type. So ALL 650 Nortons had 150 mph speedos then ??
