1980 XS1100G (Standard) Front Fork Air Valves

[Maceman]

Needing two fork air valves for a 1980 Standard (KYB forks). Previous owner overtightened the caps and cracked the schrader valve side. Looks like they are no longer available after a lengthy search. Forks are rebuilt and I just want to sort this out to have a few psi in the forks. Hoping I can find something at an Air condition supply house or something that matches up for a compressor or air tank.

Does anyone know what the thread size and type is that screws into the fork cap?

Or....if anyone has some in good condition would be awesome. I am stateside in NC.

They will be metric, but I do not have any to look at here. Check some of the other bikes from the era, as they all used the same "small parts". Look for a Kawi, Honda, or Suzuki air fork, should be the same valve.

The Suzuki part # 51293-49001 is the same as the Yamaha Standard air fork Schrader valve unit.
