What do both the chambers do?

I am a 155lbs XC rider that rides in pretty rough trails. I have put 30psi in the pos. and 100 in the neg.

What do u guys suggest?

This sounds about right,but the seals take ages to bed in.I assume you've put 30psi in both pos.chambers.If so just give it time,then start tweaking.
P.S. It's worth changing the oil after about 20 hours bedding in.

Ditto. You'll be surprise how dark that oil gets after the first 20 hours. Also, my Marathon came with too much oil and changing the oil was how I found out. After that, I got more travel out of it.

I've got the 2003 SL,and use 90cc in the right leg,and 30cc in the left,as recommended by Ventanarama.I get full travel and smooth damping.I weigh170,and use 34 +ve and 110-ve.

What sort of oil do u guys use and is it easy to do yourself?

Thanks

I use Silkolene Pro RSF,it's widely available in motorbike shops,and is half the price of Marzocchi oil.The full manual for the 02 Marathon is here:-http://www.enduroforkseals.com/sitebuildercontent/sitebuilderfiles/02marathon_s.pdf
The forks are all basically the same,as are the procedures.
