Tube valve adapter for tubeless wheels (adapter collar or skirted lock nut)

I've fitted winter tyres to my spare wheels for my Honda Varadero XL125V, the only tyres I could find are Heidenau K60 M+S SiO2 Tube type, I would have preferred something tubeless, as I use it for commuting to work.

The cast Enkei wheels are designed for a snap in rubber Schrader valve so the hole is bigger than the valve.

Tried to find as adapter but cant seen to find any online, all I've managed to find is this identical quote in various tyre safety sheets:

Quote:

When a tube is fitted and the rim valve hole is designed for a rubber snap-in tubeless valve, it will be necessary to fit an adapter collar or skirted lock nut to ensure correct valve location. Always fit a valve cap, preferably of the sealing type.

Where can I find an adapter collar or skirted lock nut?

These are simple spacers to keep the valve centred in the hole. Nothing complex.

You could try the place where you got the tyres/tubes .. they might have them or be able to get them in for you. Any machinist with a lathe could make you some... 20 minutes with an old tubeless valve and a sharp knife should see a rough one made up out of the rubber bit that goes in the rim.
