Helas to Greece!

Its a bit strange how you listed your BV.

I guess you mixed the BV and the bleedstack.

I cant figure out what is what at the moment...

You've found the 24 directly to the piston face. Which shims follow these 24?

Then there should be a thick washer and another stack. this stack is the so called bleed stack.

So I guess your BV stack is:

18x0.10

20x0.10

22x0.10

24x0.10(8)

And your bleed stack

16x0.10

14x0.10

11x0.10

But if it was mounted in the direction you posted it here, someone inverted the bleedstack.

If you're not sure post a picture of the disassembled base with all parts.

This is 2000 wrf 400 stock BV

24-0,11*10

22-0,11*1

20-0,11*1

18-0,11*1

16-0,11*1

14-0,11*1

11-0,25*1

i was founded it just like the way i post it but i just bought the bike and i dont know many info!!!so what do you all recomanded??for supermoto use??

I ride italian championship supermoto , lainer suspension who win this year the world championship with adrien chareyre . Im 85 kg and 4.8 spring i think 5.2 is too stiff!!!if the stock stack of your bike is that jusa posted you can try 24-0.11 x 14

22-0.11 x 3

20-0.11 x 2

18-o.11

16- 0.11

14-0.11

11-0.25

use maxima fluid 7w and lower oil level

you must revalve your rebound is too fast on stock setting

i am going one step at the time...next step is rebound...the spring is by spring rates at racetech.

THE PROGRAM OF SPRING DON T GIVE ALWAYS THE RIGHT CHOICE.

for your weight 4.7 is good

thank you very much for the knowledge,and any other advise would be helpful.:busted:

How felt the bike with the stack you listed in your first post?

There should be almost no compression damping.

the bike was way too soft for me...when i was hitting the brakes it was like the bars gonna touch the ground:bonk:,so first step stiffer spring i am going with cardinale199 advise and go now to 0.47-0.48 and the revalve advise...but i want and a second opinion to think about it

There is not much thinking necessary.

Your current stack is really crapy. No one who is in suspension would do a stack like this.

Test the stack of cardinale199 and go for it.

If you dont like it one can make other suggestions.

Lucky you to get a precise stack this fast anyway.

For supermoto, like Cardinale said, jacking the rebound damping way up will make that bike feel allot better.

the float on mid make an important rule on your stack

write here the mid stack comp and reb

have you lowered the bike??

no i havent lowered my bike.i just open the cartridge and i found a lot of rust...what do you think???:busted::busted:

water in fork by seal!!what part are rusted??

the spring and the valve and the shims...are they need to be replaced???

the spring can polished also the valve. the shim i don t know.what s your reb stack??

the compression if i am right(the shims from the spring side)was

27x0.10 (3)

25.0.10

23x0.10(2)

26x0.30

and from the other side is

27x0.10 (3)

20x0.10

18x0.10

16x0.10

14x0.10

12x0.10

11x0.10(3)

something doesnt seems right

i think you can try another 27x0.10 in mid and this less the float

and on reb add

2x 27x0.10

1x 26x0.10

1x 24x0.10

new oil and try the bike

you use the bike on track?or in street

the right shims is

compresion

27x0.10(3)

24

20

16

25x0.3

14x0.10

rebound

27x0.10(3)

24

20

16

25xover

11(3)
