There is a substitution table to work that out, I cleaned one up & put it online, see the link below

Yep, can't just simply replace a .3 with 3*.1's. Wayne's calculator gives the same results as the formula I've been using.

Where are you getting your shims from? WP/KTM show a 6x10x0.3 as available:

40540447 SHIM 6X10X0,3

Also, a 6x14x0.15:

40540405 SHIM 6X14X0,15

Cheers,

Tseta

Tseta,
You can buy shims here:

http://www.mx-tech.com/

They slipped them in an envelope and mailed them to me.

There's an exception to the substitution table: when the shim is being used as a spacer then you should match the total thickness. In the case above, the 10-.3 shim in the rebound is a spacer- it won't flex itself, but controls when the 14 and 16 shims above it hit the 16 shim below it. So the correct substitution is 3x 10-.1mm shims.

BTW, and I should have posted this when it happened: After a bit of riding with the new valving I decided that the front was too soft, and added two 24-.1 shims to the low speed side of the base valve. It's still pretty plush, but holds the front up a lot better in whoops and stuff. Helps with the brake dive too.

Bottom of what?


The valve in the bottom of the forks is the base valve. The low speed shims are the ones at the top of the stack, closest to the valve itself.

I went from stock:
Base: (6mm ID)
6 x 24 x .1
2 x 22 x .1
2 x 20 x .1
2 x 18 x .1
1 x 16 x .15
1 x 14 x .15
1 x 11 x .2
1 x 18 x .25

to:
2 x 24 x .1
1 x 12 x .1
1 x 24 x .1
1 x 22 x .1
1 x 20 x .1
1 x 18 x .1
1 x 16 x .1
1 x 14 x .1
1 x 12 x .1
3 x 10 x .1

to:
4 x 24 x .1
1 x 12 x .1
1 x 24 x .1
1 x 22 x .1
1 x 20 x .1
1 x 18 x .1
1 x 16 x .1
1 x 14 x .1
1 x 12 x .1
3 x 10 x .1

Terminology: There are three stacks, base, mid, and rebound. Each can have a low and high speed part. In the above base valve stacks the first 24mm shims in the list are the low speed part of the stack, the 12mm shim is the crossover, and the rest are the high speed part.

so i still am missing shimms 3 orders later hahahah not really funny!. well gotta get the bike back together so my stacks will be
2x24x1-low speed?
1x12x1
1x24x1high speed?
2x20x1 ''
1x18x1 ''
1x16x1 ''
1x14x1 ''
1x12x1 ''
1x10x3 ''
let me know whet you thing of the substitution of the 1x22x1 to a 1x20x1 should blow through a little faster hope not too fast
have to try and see i could use a 1x24x1 but that might be a little to stiff high speed if I'm getting this correct ??

researched allot but all just theory so far

What's your midvalve float? I'd make sure to get that down to the .8-1.05 range while you're at it. To me, the basevalve sounds like not enough low speed damping (large diameter shims closest to the valve body), but I've only redone my 950 forks, not my 640.

zerodog's midvalve compression stack is 1.45mm, yours is 0.7, right? You're going to have more movement than you want at the beginning of the stroke I think. There were a few different midvalve taps, you should really try to measure the float on there with the shims you put on. . . you can use stacked feeler gauges if that's what you've got.
