Rev U-turn 426's, 2007 or 2008 model I think.
What's the trick to setting +ve and -ve air?
iirc you let it all out first, then fill the +ve to the right pressure and then add to the -ve to get the desired effect?
But when I do this the fork starts to creep back down its travel. Not badly, only a few mm, but definitely dropping.
Is this normal? Any ideas?
yes normal and fine
Yes, that's normal. Too much neg air and you lose a bit of travel. not enough and the fork isn't very supple. I tend to use the same pressure in both chambers, some use 10psi more in the neg chamber, but on mine that takes away about 10mm travel.
I use about 120psi in both chambers, and I'm 12.5 stone.
All that happens when you use more -ve than +ve pressure is that it drags the fork down, the -ve chamber gets a bit bigger, and the pressures equalise... So it's largely a waste of time....

cheers all
