Quick Reba setup question

OK so I got my shock pump today. Just need a bit of info on setting up my Reba's now. Do I need to let all the air out of the positive and negative chambers first or can I just connect the pump, check pressure and release/ add air as necessary?

Also is there any precautions I should take before doing this?

Apologies for the questions but its my first time doing this and just want to make sure I don't feck it up.

Cheers for any info.

    have you read the info in the FAQs?

    it tells you how to.

    OK just found it there. So if I turn the bike upside down while letting the air out of the negative chamber and then turn it right side up for letting the air out of the positive chamber I shouldn't lose loads of oil?? Just don't fancy having to take em apart to replace oil as I don't have a clue how to. If there's a sticky somewhere with these info feel free to let me know as I couldn't find it. Cheers

    Good question, I read this and wondered exactly the same things as yourself. The guide is good, but lacks some essential detail.

    You don't need to turn it upside down, but it can help with the neg air chamber. It is not damping oil, but lube oil. RS don't even say to do this.

    Let the air out the negative chamber first, then the positive. Then refill the air, negative chamber first. Not sure about Reba's but my Rev's say on the inside of one of the legs what pressures to put in according to rider's weight. When you unscrew the pump there might be a little bit of oil shoot out from around the pump head, don't think it's anything to worry about but I'd check with Nick, he'll definately know :)

    Hope that helps, goodluck.

    don't follow the RS pressures, they're rubbish. Set +ve to give sag then -ve to taste!

    I agree with ride_whenever, going by the guide I should have about 60-80psi in mine for a rider around 70kgs. But I've set mine to 150psi. Best thing to do is just set it at what you feel would be right, then go for a ride and take your shock pump with you to adjust it until it feels best.

    and i wonder why RS no longer list pressures but make SAG on their fork leg inners.

    Pressure has nothing to do with just set the SAG and then equalise the pressure and then tune to suit.
