2012 CRF 250 stock stacks

Recommended Posts

Thanks for the stacks!

Rode it only once, I need to ride it more but I found the suspensions stiff, especially the rear end. I like soft suspensions btw. 145lb intermediate mx, mostly very hard pack. Gonna put a 4.8 spring and 310 cm3 fork oil first and ride a it bit. Fork springs might be too heavy for me but I want to try it for now as I read the forks benefit from heavy springs. What do you think?

I am thinking about this for the first revalve :

BASE

32.1 X 25

30.1

28.1

26.1

24.1

22.1

20.1

18.1

16.1

14.2 X 7

=>

32.1 X 17

30.1

28.1

26.1

24.1

22.1

20.1

18.1

16.1

14.1

12.1

10.3

MID

20.1 X 4

18.1

16.1

14.1

12.1

11.1

11.3 X 2

17.3 X 2

=> nothing for now as I read 4 face shims is a good set up (though YZ250F used to have only 3 and I really loved these forks!)

REBOUND

20.1 X 3

12.1

18.1

16.1

14.1

12.2 X 2

=> not sure yet but might use a 14 clamp

SHOCK COMPRESSION

44.25 X 2

44.2 X 10

37.15

23.15

44.25

42.25

40.25

38.25

36.25

34.25

32.25

30.25

28.25

26.25

24.25

23.3

25.6 X 6

=>

44.25 X 2

44.2 X 6

37.15

23.15

44.25

42.25

40.25

38.25

36.25

34.25

32.25

30.25

28.25

26.25

24.25

22.25

20.25

18.25 might be too much?

25.6 X 6

SHOCK REBOUND

40.2 X 5

25.1

40.3

38.3

36.3

34.3

32.3

30.3

29.3

28.3

27.3

26.3

=>

40.2 X 5

25.1

40.3

38.3

36.3

34.3

32.3

30.3

29.3

28.3 (to avoid getting sideways on the deteriorated faces of jumps)

What do you guys think about it?

I think I would keep the clamp the same as oem on the fork base and shock comp , all the other mods look ok

I read that the mid float is .35.

Why not smaller clamp shims on the base and shock comp if I want to soften the HS comp?

you soften the overall stack with a smaller clamp, not just HS.

Its gonna be really soft since you already removed a couple of faceshims.

OK, I know thay but I don't know by how much you affect LS with a smaller clamp.

What would be the difference in LS comp between :

32.1 X 17

30.1

28.1

26.1

24.1

22.1

20.1

18.1

16.1

14.1

and

32.1 X 25

30.1

28.1

26.1

24.1

22.1

20.1

18.1

16.1

14.1

12.1

10.1

i never used a smaller clamp on base valve for mx use then 14.

if you run 17 face shim and the stock base you have a good softness then stock

but is important the float on mid valve

Thanks for the link Vietze. Didn't think a clamp change would have so much effect on LS! There's no precise rule though... but I understand better why my proposed stack might be too soft.

I am thinking about a smaller clamp because my idea is that it's better to soften the whole curve (damping VS speed) than just lowering LS and steepen the ramp to the end of the curve (wich will remain the same).

Yes Carnidale, I ride mx only on hard pack for the most part. I will first ride it more with the 4.8 spring and 310ml oil. But maybe not this week end as it's freezing here right now!

Tell us what you think later racerfmx.

Another question guys : a small washer/cup fell off the compression adjuster while I was draining oil. How do I put it back? Round side facing the adjuster?

Thx!

that base stack works well. however I would take the float to .20 on the crf because of the chassis issues. It helps eliminate the diving of the front end entering turns. That's been working well for me.

What is your set up Chad?

I have not had problems entering turns or in staight line stability yet. Maybe because I have .45 and 4.8 springs?

Anyone for the "washer/cup" remounting? I'd like to reassemble tonight!
