Ok, I'll get it apart when I get home today and post up. Thanks gentlemen!

racetech do a 10 ics spring got them in my 013 mar cc. the problem i had was the fork was good flat out not so at lesser speeds so i softened the ls comp stack and used 16 cts oil think iv got 4.2/5.2 im 180ish. im on one from stiffest on the spring pre lode clip i do think it sits in the midstroke a bit thinking more spring pre lode or one 4.4/one 4.2 spring . has the 888 bean served recently as the gas piston runs out of oil gap over time

Yeah, I haven't serviced the shock since I've owned it and suspect it is due.

Ok, my compression stack is...

Bolt
Spring
31.85 x .3
piston
11 x .3
11 x .3
18 x .1
20 x .1
24 x .1
13.8 x .1
31.8 x .15
31.8 x .15
28 x .1
2.5 spacer

My rebound stack is...

Nut
11 x 2.5 spacer
11 x .10
11 x .30
14 x .15
17 x .10
20 x .10 (3)
12 x .10
piston (larger opening facing nut side and there is a small bushing/spacer in it on the same side if it makes a difference)
20 x .10 (2)
11 x .10
11 x .25
18 x .15

Any ideas on what I can do with what I have?

Jakobi 12-02-2018 10:01 PM

This is your rebound stack..

Nut
11 x 2.5 spacer
11 x .10
11 x .30
14 x .15
17 x .10
20 x .10 (3)
12 x .10
piston

You more damping.. I'd take that 12 x .1 off the piston face.. All it does it let a load of oil bleed on past the stack. I'd slip it in around between or under the 20's.. as I did on mine (see below).

This is what I have in my set..
Piston
20x.10 (2)
12x.10 - bleed moved down to crossover
20x.10
18x.10
16x.10
14x.10
12x.10 - from BV
11x 2.5 - collar

Cool! Thank you! I'll get it done and report back as soon as I can test it.

Got everything put back together and rode it on Sunday. Rebound was way better. However, now I'm at full soft on the compression. Doh! Only other change was going from 300cc to 320cc on the outer chamber as the forks had almost no bottoming resistance before. Lost some plushness but at least it doesn't beat me up. I'll be fine with them until the next service and then maybe I'll play with the compression side of things. Thanks for all the help!

BTW, I made a video of me servicing the forks. I'll post it in the big Marzocchi 48mm PFP thread. Hopefully it will explain a lot of things for those wanting to service their own 48 PFP forks. Sadly, it is somewhat comical with my little mistakes and my use of words. :p

That 12mm face shim holding the rebound stack off the face could have been letting some fluid back through as free bleed in the compression direction too. Depends if the force is enough to flex the whole rebound stack backwards over the ports to close them off.

Pulling a 20x.1 out of the mid comp or even letting a touch more free bleed past the base (maybe a 26 or 27mm bleed shim vs the stock 28mm) might move let you find the happy place. Not hard to drop a few mms of oil out of them in the interim either.

Just did a race this past weekend that was mainly MX track and whooped out sand wash. Used all of but 3/16" of my travel so I think the 320cc outer is about perfect. Still have the compression set at full soft and PFP at 0 and the bike actually did really well on this course. However, the next race is a slower, more technical race (lots of rocks) and I'm worried the forks are going to send me off course and that can be quite dangerous in certain sections. So, I don't have any other shims to play with but I think I gotta try something.

Jakobi, you said I could remove the 20x.1. Would I completely remove it or move it to the end of the stack with the collar? As far as the 28, the one furthest from the piston, that is considered a bleed? I thought the ones closest to the piston, being very small in diameter, are bleeds or am I wrong? What would be the effect if I swapped the positions of the 28 and 24 shims? Sorry, I'm really trying to understand the philosophy of how the valving works and want to make sure I understand correctly.

Sorry, I have confused you. I read the base valve stack wrong and figured the 28 was against the piston. The stack is very strange that it tapers a lot of bleed and then clamps on the 28.. Are you certain you recorded it correctly?

I also looked at your stacks again and don't think I would change the mid comp stack too much. It only has 2 x 20.1's already..

Did you mention what the float clearance is?
