Uprated std front shock valves ???
I have heard from many different sources that there used to be and still is available an uprated valve that swaps straight over with the std valve on the front leaver arm dampers. Dose anybody have any or know of where to get them from. I have been told that there is a guy in the midlands (Warwick area) that has them but I have no contact details for him.

I don't know what Minor front valves are like but the A35 has the same as Midget.Rogerv wrote:Uprated std front shock valves ???

That means you can simply buy standard Midget items to uprate A35 shocks so maybe the same Midget valve will fit on the Minor.
The (A35) club magazine had an article about the valves.
They are adjustable and then locked in position with solder.
It's a simple case of heating until solder melts, adjusting for different damping restriction and then resoldering.
Personally I don't fancy that method myself and would prefer to buy "factory set" / uprated valves.

Not heard of those in recent times where do these sources get their information from and what would be the advantage in just changing the valves on their own.I have heard from many different sources that there used to be and still is available an uprated valve that swaps straight over with the std valve on the front leaver arm dampers.

As far as I know all Armstrong lever arms have the same valve fitting, so the valves are interchangeable.
The valves are what controls the flow of oil, and so the resistance (and therefor damping). This will put more load on the parts that move the oil through the valve (ie the seals/ pistons/ cylinders), but that load should be within tolerance (when the dampers were new - It might be too much for 40 year old ones!).
So changing the valve will give a different damping rate. Think of it like a Spax adjustable, except instead of twiddling a screw you're swapping valves till you get the damping you want
