    Rough guides are written on the fork, and in the instructions. Pump up the positive chamber first, then the negative to the same pressure. You are aiming for 25% sag, but experimentation is the key, and the negative spring can be used to the initial part of the stroke.

    do you have the manual? down load fron RS's webby. they have it all explained in there.

    sag is the travel used when on the bike in riding position.

    25% sag would be 25mm on a 100mm fork.

    yes. normally when there is too much oil in the lower chamber.
