The ATE front ends have a rubber bumper at the bottom to stop the clank on top-out. They should be available from the dealer, but the top-out springs, I don't know. They're just a spring as I recall, and perhaps a spring shop could duplicate them. I've got some around here somewhere, but have no idea what rate they would be, though I could give the dimensions.
I have to agree with you on this one.
The ATE fork works very well if it's set up correctly. When I rebuilt mine, I used a set of medium stiffness progressive forks, the rubber bumpers and 7.5 weight oil. I also added a billet top clamp and a Telefix brace and now I have the best stock Airhead front end I've ridden so far. It's smooth and very compliant.
I have heard that a good anti-dive spring is a pair of Chevy 350 valve springs. I'm going to install a pair and I'll let you know how they work but the tip cam from a pro Airhead wrench, so it might be a good one.
