I'm nowhere near anywhere I can check, but believe it is the same thread as the chain case cover drain/level plugs, that being M16 x I.5

You're bound to have one of those to check with ;)

I'll check tomorrow. Sods law that I've got a 16 x 1.5 die but no tap. Cheers.

I should have the tap, if you need to borrow it.

I'm fairly sure that I used a level plug to blank off a speedo drive hole for racing :oops: I soon realised that weight saving was a lot more important than adding bling......

Yep think that's right M16x1.5 - I think I also have the tap somewhere if you're stuck.
