Hi, I have a 1955 B31, which has a M33 engine in it.  Chasing an oil weep on the bike I took the rocker oil feed pipe off, only to discover the oil feed rocker banjo screws are different lengths.  Is this correct? Looking at the parts manual & Draganflys website it should be the same part number, therefore the same length?
Should they be the same length?
If yes which ones correct, the long or short one!
Any help would be appreciated.

I don't know which are correct but mine look like your long ones.

Thanks for the reply.
Counting threads from the pics on Draganflys website the long ones seem to be correct, I think i will treat myself to a new pair!
