Yes. it held air after the oil change - strange thing.
And I found this somewhere and followed some of the advice for the 100mm fork:
First impressions were that it was stictiony, ramped up very quickly at the bottom of the stroke,
and the damping settings were either too fast or too slow. After reading a few reviews, I contacted
tech support and found that they recommend running the negative chamber at 3X the positive. This
really reduced the stiction, and as time has gone by it has gotten really smooth. The tech made no
mention of oil levels. I rode it 5 or 6 more rides, feeling all along that I was short on travel
(should be 100mm). So I called tech support again and asked for the full skinny on the fork. His
first question was how much oil I was running, which was 115 and 30cc (per the manual). He said I
need to drop it down to 87cc and 35cc, that that would make a huge difference. It did, with the fork
feeling very smooth and progressive, damping just right. This also made a big difference in required
air pressure, I bumped up to 30psi pos, 100psi neg. However, on a ride this weekend in Farmington,
NM while hitting high speed dips the fork bottomed out really hard twice with a loud bang. So I
raised the pressure to 32 psi, which made it quite a lot harsher, but it didn't bottom. I called
tech again, asking if I could add oil to make it ramp up more on the bottom of the stroke to avoid
bottoming. He said very little, max of 5cc extra, as more than that would make the fork hydraulic
out (now I know why my travel was so short in the beginning!) I am going to try adding 3cc of oil
per side, and play with the negative pressure to see just how fine I can tune this thing. The fork
is starting to get close to what I want, with much tweaking. Anybody wanting to run this fork needs
to do their homework as far as pressures and oil levels and weights, those are your only tuning
options and small increments seem to make large changes in the performance characteristics. Overall,
I am very pleased but feel that Marzocchi needs to get their act together as far as the manual, and
tech support needs to immediately advise people that the oil levels are so critical.
And If mine dies I've got my eye on a Fox product. Not sure which. Coils certainly seem more
reliable at this point.
