FRONT FORK AIR BALANCE KIT

Can anyone out there help me ?

The KZ /Z1300 A1 & A2 came with air forks but they were not balanced.
The A3 came with balanced forks, but it was due to the fork legs having a hole on them & a metal ring with covering the holes & being linked. This means it is obviously not a Retro Fit Kit for the A1 & A2.

I am looking for an Air Fork Balance Kit that will simply screw onto the Schrader Valve Tops on the top of each fork & balance the 2 forks with a pipe or hose.

Progressive Suspension made a kit to do just this, but I am finding it is discontinued & not available in the UK.

Does anyone out there have one of these kits they will sell me or maybe have a supplier in their country that they can buy one from ?
Or has anyone made one themselves & can share how they achieved it.
For someone with basic metal work facilities it would not be a hard job using 2 x 90 deg schrader valve tops & some hose ??????

I am more than happy to send payment to any owner who can help me with this ?
