Shim stack ktm 250 EXC 03

[canonndalemx]

Has anyone done any mods to the fork to improve it for rocks and roots?
On sharp rocks or roots on a fast section ,the fork deflects off the objects instead of absorbing the impact.
The terrain i ride in are mud and rocks
My weight is 210. I have .44 springs in the fork and pds 3.
Oil level is 150mm from the top.
Any input appreciated.

I have removed the compression-valving unit from the bottom of the forks and examined it.This is what I found.

.10x24
.10x24
.10x24
.10x24
.10x24
.10x24
.10x22
.10x22
.10x20
.10x18
.10x16
.10x14
.30x10
.20x18

Can any of you suspension wizards point me in the right direction?

If i remove the .10x16 will it make the fork softer? the fork never bottoms.
Do these mods make sense?

It will make it very slightly softer-look at the 24mm shims to make a larger difference.

Take out two .10x24s and one.10x 14 then if you have them make up the difference with some .10 x12/ . 10 x 11sunder that .10x 18( Base valve)Then raise the oil level a bit if it bottoms. i have this moly spray that I spray on new clean fork seals that helps combat stichtion at the seals Then I use oil on them . if you assemble the triple bushing forks without oiling the bushings good then they will drag a bit when first used I also like to stagger the ends of the bushings when Installed. Thers been talk of grooving the upper bushing (outer) to help let oil in.

I guess i came across wrong but I meant four 24s/ two 22s/20/18/12/11/10then build the end back up with the 14/16 then the 18 you took out or leave them out if no space. Sometimes it can be good to have a reverse taper at the end to sort of cushion the real wide shims as it can help keep them from breaking esp. with a thin light stack . Sort of like a hourglass shape. I just try not to ever go back to the original size at the top for possible restriction at the bottom Espescially at the midvalve but thats a whole different story .Sometimes theres a flat washer there or a base plate. Good Luck. Hope I made sense cause sometimes I dont!?Where Im at in Jersey theres alot of rocks and roots and long bombed out sandy whoop sections that need catering to also. How bout Sweden?
