These are the rechromed stanchions installed on the

As they were picked up from A1 Hardchrome.

Had my NOS fork stanchions rechromed by A1 Hardchrome in Lidcome.
They did a great job

The bore share the O ring would seat is 28.45 mm, so I guess the OD of the thread would be 28.
The thread pitch is 1.5 mm.
The internal diameter of the thread is 26.5 mm.

I’ll check these dimensions again tomorrow just to be sure.

Inmotion Trials had NOS 172 stanchions for sale so I bought them.
Now, my original stanchions and the NOS forks both have ...

Didn’t realise it had been so long since my last update
As my front fork tubes were pitted and the bottom sliders are worn I I was going to have the tubes hard chromed and sleeves fitted to the sliders.
However I found a set of NOS forks and bought and installed them.
Was going to upload a photo ...

Doh! of course you're right Phil, A 2 banger is a different fish-kettle. It would be down to bore and stroke calc to get the swept volume.
But it's still a good way to measure head volume, so useful for establishing comp ratio.
