'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.

What is your free sag set at with 105 rider sag?

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.

Have they been serviced since new? Hours?

No service. Probably 60 hours
