Anybody running just air in their coil fork?

I normally run one spring and <5PSI in my '06 Z1 Sport (I weigh about 160 in gear). Today I pulled out the spring and aired up each leg to about ~15-20 PSI each (I have a valve in each top cap on my fork). The manual recommends not using more than 15PSI in each leg, but I did not blow anything out on the trail.

Compared to the spring setup, the air feels like it actually had a more linear mid-stroke, which alleviated some issues I had earlier with the fork packing up. I also messed slightly with the dampening, so that may have had some effect too.

Tomorrow I am going to try pulling out some oil to increase the air volume. I wonder what the fork weighs now :greedy:

if you changed the damping that is what affected the packing up. packing up is purely your rebound being too slow for the conditions, nothing else. and i doubt the air had a more linear mid stroke....air is progressive under ALL conditions. the spring is going to be the most linear with no air pressure, and as you increase the air pressure the more linear the fork will become. what it might have been is that the fork was plusher than with the springs. that is a little more likely.

Yes, that is probably it. Or I am just thinking it felt better - I actually was running a slower rebound stroke today than I was when I had the spring in.

what trail did you end up riding today, wanna ride tommorow.:brow:
I did two runs on the DH trail today, maybe going riding there tomorrow.
