We want to make a single schrader valve tapped into a splitter, then 2 hoses that goes to both upper chambers, joining the chambers by a common hose so that pressure is equal between them. Something similar to - http://www.motorcycleforksairequalizer.com/
We can do the same on the lower fork tubes, one schrader valve goes into a splitter to both fork tubes via a common hose and both fork tubes have the same pressure. Scott is going to design and machine the parts (yes, I am volunteering you, Scott). I will supply the money for the schrader valves, various parts, hoses, etc. I found a good example of this set-up, simple and easy. I will search for it and post a link when and if I find it again.
