these are some sort of air fork attachment that are from a old dirt bike shop from the mid-late 70's. Does anyone know what
brand they might be? i was thinking maybe Luft in California? I have never seen these before.
what i think they are is similar caps to the 76 YZ's but they attach with a hose. They have 2 air valves and im guessing there is a floating piston inside that separates the low pressure from the high pressure gas?
