I've really appreciated the quick response from the owner as well. In my original order one of the pieces was defective, it wouldn't hold air - he had me new stuff within 2 days.
Bummer it didn't work for some of you. Comparing my .62 fork springs to the AirPro set at 15 psi and stock fork springs - the ride height was identical. Remember, recommended PSI is 6 to 12 PSI, if some bikes require more than that to get the correct ride height then you better plan on more than just the AirPro.
After I got mine, a buddy got one too for his 14' KTM XC 450. It worked perfect for him. He ran 15 PSI as well, no issues at all.
Summary
- .62 fork springs, AirPro at 6 PSI. Almost too stiff. My 17' TSS LE with 21" of travel bottomed out before the front forks did. But that's what I set it at when doing big stuff. I ran it at 3 PSI most the time.
- Stock fork springs, AirPro at 15 PSI. Perfect for the guy who doesn't jump any bigger than what you saw in my video. This is of course, on a YZ. I guess every bike will react differently based on bike setup.
I should say, the length of the TSS or SS makes a huge difference on bike setup. If that isn't set correctly, then not even heavy fork springs or the AirPro are gonna help you. You need that angle correct first. I really love my 14' YZ because it was dead on perfect right out of the crate. Perfect ski pressure, perfect ski feel (not too much or too little push), just handled awesome. That was with heavy fork springs OR with stockers and the AirPro at 15 PSI.
I've fiddled with my other setups quite a bit before I got them to feel right.
Anyways...
