You need an oil suitable for these old engines with low detergent, this allows the sludge to fall to the sump as the early engine has no filter and the later one with filter only filters at 25% rate.
I use Morris oils they have an informative web site and ship but don’t know if they go international. Look for the classic and steam section.The site is instructive on the types of oil available. Miller oils also have similar products and I’m sure others will as well maybe more local to you.
I’m using their gearbox oil, non EP, it’s safe to use with bronze bushes these early gearboxes have. Mine is good with SAE 90 gearbox oil, I believe this is a similar viscosity to SAE40 engine oil. I use SAE 140 gearbox oil in the final drive and happy with that.
I don’t know if you have found an answer to your speedo cable length, if not I will be able to measure mine in a few weeks when I can get to the bike, it’s currently in storage until I move house.
Thank you Ian I still need
