Stock shim stacks for 2008 RMZ 450

Does anyone have the stock shim stack specs for a 2008 RMZ450? Front and Rear.

I may be tearing into a bike for a friend and would like to begin thinking about the changes to make for him to make things a bit plusher for trail riding.

Thanks in advance,

ben

Wow! That is one heck of a stiff setup stock. Does anyone know if the Suzuki's have some kind of valve piston design that is different than the CRF Showa's that justifies them having such stiffer valving?

ben

i think the only reason it doesnt seem crazy stiff is the cross over gap, its 0.35mm so the low speed stack is actually doing most of the work, i think i went to 4 face shims on a 08 rmz 250.

Mog, can you ellaborate some more?

Having never seen the stock RMZ stacks before, the info that babilon posted is puzzling to me.

Also, what do you think about this for a new stack for him. He weighs about 175 without gear, and since he is a trail rider, he is carrying water, tools, etc., in addition to regular gear. I'm basing my ideas on what I know about CRF suspension....

not all forks use the bleed stacks, i like your shock stack but maybe reduce the hs a little as well, but the fork one looks very soft with the 11clamp and the crossover will make it even softer?

i would go the other way, leave the base valve stiff by removing the cross over and open up the float to 0.35mm.

So either do the cross over or the clamp shim, but not both?

How can I make the HS softer on the shock more so than it is already?

ben

Exactly,

on the shock you could remove every other 0.3 shim, or make them all 0.25s.

I think I'll go with the cross over shim and leave out the clamps on the BV.

On the shock. I already removed the odd numbered shims from the shock, like we typically do on the CRF. I also removed the 44 on the top of HS, I suppose I could remove the 42 as well.
