Help with getting air into strange tyre valves!

Be very happy you have one of those caps. I don't think any tubes I have bought in 20 years now had them so you need to search your old bins or actually buy them.

They are required to be fitted on race bikes here.

I’ll never forget as a teenager working on my first bike BSA 250. I’d taken it to an old guy and was pestering him with questions probably stupid ones and he told me to go to the tool box and find him a left handed screwdriver. So I did. Took me a while before I realised.

This thread makes me nostalgic.
When those valve caps was essential combined with a tube repair kit.
Your motorcycle had a tyre pump.
The toolbox contained tyre levers. break point feeler and file.
And the riders handbook told you how to decarbonize piston and head.
When horses was common, spreading horse shoe nails on the roads.
When motorcycles had inbuilt paddock stands and flip up rear mudguards.

I could see how those valve caps could be mistaken for Presta valves which are common on bicycles.

I can't, but then, I'm an arse!

I don't have the naval experience of the earlier responder, but can confirm that the RAF training and operational bases I served on had the same attitude to the new guys!

They would send you to the other hanger to get a Skyhook or a bottle of Prop Wash. LOL.
I worked as a ramp rat in the early 1980's... the technical term would be a Petro Chemical Transfer Engineer, as Buffalo Joe would say. (Ice Pilots). this will make you smile
