I know with the standard dual air you can reduce travel with a spacer. Can travel be reduced on a U-turn air? Have an older Revelation 100-130 I'd like to put on my kid's bike but would need it down to 80mm to make the geo realistic.

Not sure of the model, but you can reduce the travel with the Pike 454s, using the same spacer method.

Hey mate,
I have a set of revelations too, there's a way to reduce the travel using the negative air chamber. A lot of people complain about it, but its actually pretty useful.

All you do is put more air in the negative chamber than the positive, the more you have, the more travel will be reduced, I've been doing it on mine for 6 months and it works fine!

Hope it helped.

the negative over positive method causes the fork to bottom easier, much easier than it is supposed to do, and also pack up over bumps.

You could also cause the fork to essentially bottom and never come back up too

Negative charging in this fashion should only be used for making the fork feel more supple, not adjusting the travel.
