Question '12 rear sag/preload

What are you guys running on your '12s? I've been running about 9 - 9.5mm preload for a 110mm race sag. Not bad but just curious if someone has tried something out of the box for a good result. When its really slick I think the bike could use a little more weight on the rear, so maybe a little more sag.

I'm not sure about how much preload I have. I have the sag set right at 105mm though. I am about to re-spring the bike though. It feels like its settling in the middle of the stroke and rides a little harsh.

Whats your weight/ability? I think this bike with stock 5.2/.42 feels significantly stiffer than my '07 with the 5.4/.44 combo. I figured its because of the CC fork, and perhaps the rear link ratio is slightly different, although this is just a guess not fact.

I'm 205 without gear.. Some days I'm a fairly fast Vet A, some days I should stay in bed..

On my 05 I have 5.4 and .46 and a revalve and there were days I felt it was too soft..

Glenn, what is your rider weight?

Too bad we cannot get a owners manual for the 48CC forks. The Marzocchi site has an online owners manual for the 50mm but not the 48.

I'm a 176 lb(naked) B rider. I don't usually concern myself with free or static sag, prefering to use shock spring preload as a guide and staying under 10mm.

I'm comfortable working on the fork now that I figured it out. As long as I can get parts I don't need a manual. Its actually easier than a KYB in some ways as nothing is crimped/peened. The compression face shims are an odd size(small 8mm ID for a large OD). I think it runs a higher cartridge pressure than a KYB even with the PFP backed all the way out (still 7mm preload). I'm going to try reducing the main spring preload, down to 1 or 2mm. This will mean some special parts. Its not bad but there is room for improvement on the small stuff. It might feel a little worse without the FlexBars.

I noticed just last night that I am getting a little bit of the clunking sensation upon top-out. It is also getting noticeable play in the bushings. I am due for a service so all of my issues will likely be solved after that.
