I tried out this method. I split the difference and set it at 11mm. 18 COMP, 20 REB. I didn't check the hi spd. Being a brand new bike, I didn't measure the sag. I figured I would let the suspension break in, then take measurements.

I measured my sag(s) with the following -- street clothes, empty tank, with a 25-pound weight in my backpack. I weigh about 190 in street clothes.

Shock measurement:

Free sag (settling under its own weight for those not in the know): 36mm

Race sag = 108mm

Fork measurement:

Race sag = 43mm

While the free sag of 36mm might be a bit high, I'm of the mind to leave things alone for the time being, and go hammer some test whoops this weekend to see how it behaves.

The forks are likely going to want at least a 0.44 set of springs. Rear sag could stand to be decreased to 103-105.

I would suspect that as well, but I need to prove it to myself, first.

One size up on the forks, perhaps. Lets see how they perform tomorrow. I wouldn't be surprised to see them be okay for me.

Do you think I'll need to go up one on the shock or can I crank the spring a bit?

Fastest way to a crappy ride in the rocks is a soft spring with a lot of preload. Those numbers seem almost too good for a 5.2 rear spring. I'm at 5.4 on my '07 and its borderline soft for me @ 176 lbs. The '12 likes a softer spring so a 5.4 is it.

I agree with this. I'm 180 lbs and have 38mm free about 115-118 rider and 12mm spring preload. If I add anymore spring preload ride gets harsh. I ride rocks almost exclusively and do not carry tools on my body. If I rode a lot of sand and whoops heavier spings would be in order. Others on this site would give better guidance for whoops. The Michigan guys live in the sand.

On a separate note : I had a pair of 126mm LTR links and with them I can run more spring preload and the ride stays good. These links are on my 2005. I can set the bike up with 95mm rider sag with these. The Arizona terrain that I rode is similar to what I ride in the summer in Missouri.

I've got a couple of 5.6s if you want to give one a try. Like it and buy it or send it back postage paid.

What fork springs go with the 5.6?

Typically 0.46
