I've been doing a little research on fork air tanks. They seem to be a pretty good setup for taking away some of the harsh feel of the front forks. I've got a bunch of links and info on what's available and also DIY setup's if anyone is interested.

Any thoughts ?

The tanks are supposed to work great offroad. From what I've read, they really soften up the low end of the stroke while maintaining good bottoming resistance. Kind of like running low oil levels without sacrificing upper level firmness. The offroad guys over at KTMTALK love them.
The tanks are kinda pricey, but you can build for $50 to $100 depending on the metering valves used.

Here are a couple links to some DIY setups.

There are a couple different approaches to fabricating the tanks. Single or double made of aluminum, pvc and just plain tubing.
The metering valves can be either meter out of forks/ free flow back or meter both directions. Two camps on this, you’d have to make a choice.
The fittings and hose are readily available online.
Sorry for the short reply, but I had shoulder surgery last week and I’m having a hard (and frustrating) time typing with one hand. I do have a bunch of notes (Word doc’s), links and pictures That I could “zip” up and send to anyone interested.

My thoughts- The stock KDX forks are not harsh in the area where the sub-tanks work best if your sprung correctly and adjust your compression valving.
Those of us with WP forks have not really figured out "why" the forks are harsh - hydraulic lock due to piston valve sizing and/or design; mid-valve problems; ratio of fluid flow through damper rod vs base valve; hydraulic stopper length; the third bushing on the 03 and 04s; stiction issues with WP seals; etc.
Those with KX forks may benefit for off-road riding - but then again you can revalve the forks.
