Ariel would have used BSC, since UNF did not exist in 1929 and BSC/CEI was widely used in the two wheeled manufacturing industry.

That's rather tempting...

Item 4?

The Draganfly website suggests that they are in stock - at least for Mk1s. PN is 75-00 I think - I looked it up a couple of hours ago.

Next winter, I aim to find the time to address a pushrod tunnel oil leak on my Mk1.

Must I replace the Otto gaskets or are they reusable? I believe they are a fibre gasket with a mesh to stop them moving in the joint, so I am thinking they cannot be reusable?

Conventional wisdom is to put enough in to just wet the chain. Fill it up to the level plug and it comes out... I do it like this and it doesn't seem to be a problem, but I do check it pretty frequently (weekly). You will have seen a few broken primary cases on the forum I bet! I'll leave others to ...

How much oil did you have in there Gui?

Great to hear you are up and about!

Presumably the original stamping has been ground off or is missing?

Really? thanks for the tip!
