07 YZ450 Shock: How to add a bleed

[mog]

That's an odd rebound with the 0.25 will make it softer, I would run a normal stack with 0.3 in hs

I have come across several stock stacks from 06 thru 09... they all had the .25s, then finished with 26.30, 24.30

Maybe that progressive spring and 18mm shaft has something to do w it.

Well, the 450 has .25 hs shims but a 24mm clamp.

The 2 strokes use mostly .3 hs shims and a 22 or 21 clamp.

So KYB kinda uses a bigger clamp to compensate for less hs shim thickness.
I dont know why they use different stacks in the different models.

I used that reb on many 125 & 250 YZs
3x36.3
28.1
36.3
34.3
32.3
30.3
28.3
26.3
24.3
22.3

That stack works with the clicker hat 15 with a 50 or 52 N spring.

You caught my post b4 the correction. Yes my clamp is a 24.30

On my 01 YZ250, I am using your stack with (7) 36.3 on a revalved 01 YZ426 shock.

I did find it harsh when hitting breaking type bumps... which would indicate packing... think I'm about 10 out on the clickers.

7x36.3? Thats insane!!! How do you find that much space on the tap? :-D

That shock came stock w. (6) 36.25.

It tapered down to a 23.30... i added another shim and brought it to a 22.30
