The Rockers, on the inlet side, for my 51, A10 Plunger being part numbers 67-264, Inlet N/S and 67-265 Inlet O/S are different.
The N/S rocker has a "large" oil hole and a slight recess (bit like a screwdriver slot) for want of a better description, in each end. The O/S rocker does not have the oil hole or the slots.
Both Exhaust Rockers also do not have the hole or slots. Photos on Mikes Classic Spares show both Inlet rockers having the hole and slots. My Rockers have the correct part numbers on them.
Which of my Inlet Rockers is the odd one out? Did B.S.A introduce the oil hole and slots in the ends at a latter date?
Thanks Guys for any thoughts.
Cheers Russ
