2011 250sx fork settings that work pretty good .

Recommended Posts

Well I tried the race tech stuff etc.. have had the forks apart a few times trying different stuff . Here is the base valve setting and it works pretty good

put stock pistons back in .

12x24x.1 go to 9 350 oil height 15psi bladder

23x.1

22x.1

21x.1

20x.1 remove

19x.1

18x.1

17x.1

16x.1

15x.1 remove

14x.1

13x.1

12x.1

11x.1

10x.1 add this shim to base .

24x.25

Midvalve

3x20 .1s

2x18 .

1 x16

1x14

1 10.2

11x.25 add this shim to take float down leave stock backer under this .

18x.40 is the backer . I got a first and second tonite just got home

second In plus 40 got tired last lap was leading finally got passed two straight aways left . Rutted sand and clay mix track coming up short on the tables I didnt bottom track was wet and rutted . will report back when I get on a hard pack track again all in all pretty happy . The goldvalves were a waste of money . (Stock base valves work better) . I added pillow top grips and the Ktm pdhs with the spacer didnt really get arm pump not sure if those helped or not . I find I rode on sat all day so might be the reason I didnt get arm pump tonite who knows. I'm 200 Lbs with gear and have pds 6 spring on rear stock valving and .46 springs in front .Pls excuse the poor grammar Ps when I had forks apart last nite I also greased the fork seals for less stiction seemed to help .

thanks for posting that dan

I have just done a set of 350 forks , was on full stiff

so this is what I am trying

3 extra face shims on base

float reduced from 0.7mm to 0.35

23psi bladder pressure

3mm extra preload on springs

but 360 cc instead of 380

we will see how it works , oh yes and Skf seals as STD lasted 7 hours of which only 2 hours was mud

Oh the skf didnt work very well then ? Ps I left the small spacer in on the midvalve . My reasoning behind this was because it allows the stem to maintain its length to allow more movement on the face shims before hitting the backer shim . I know alot of guys probably just remove this shim to obtain the desired float . IMO then the midvalve would hit the backer shim to soon and make the front end harsh . I rode the 350 On sat and agreed front was to soft I would imagine the heavier springs would help along with reducing the float I would be careful on how much you tighten the base though I found I had to go the opposite way and make the base softer . But the 350 may like different settings Let me know how it works out for you ? ps with heavier fork springs I would worry about 23 for bladder pressure make the front end ride to high for corners and not settle But then again worth a try for sure .

i would have not gone with more preload or bladder pressure or as stiff if we had a set of stiffer springs , but it's a bit of a band aid job , he doesn't want to spend too much as he is unsure if he wants to keep the bike

soon adds up

service

Skf seals

springs

if you don't want to keep the bike

the STD seals were the ones that didn't last

Oh understood on the pressure now It really does need the stiffer springs though as I think stock they are only .46 .

Well Maybe they could be made to work but It might be like ten times having the forks apart to make that happen honestly the stock valves work pretty good now . At least with the stock ones you have a baseline to start from . the race tech wasnt even in the ball park was way to soft . I just wanna ride and didnt feel like taking forks apart everytime I rode to change settings so was just easier to start with a known on the stock valves and tune from there .

ktm say the 350 springs are 0.48 which is actually 0.49kgmm but others say they are 0.46 I have not seen a STD spring that out of range but it would be good if someone has tested a STD spring ?

0.46nm and 0.47 kgmm you mean? rt say this but they maybe going from ktms manual?

Stock Fork Spring Rate 0.49 kg/mm (stock)

Yes your right stock are .46nm so that translates to .47 kg Just going by what I was told at another shop as per stock spring rates .

i know for a fact that the 350 i rid here in nz was a euro version and it had the .48/5.4 combination, the only thing that put me off the 350 was it felt like it ride real high in the stroke when coming into corners specially flat turns the suspension didnt compress as much as it should to get good traction almost a stinkbug feel runing 102mm race sag and im 160 punds not a feather weight

you need to run about 110mm to help with the stinkbug feel , and you need a 5.2 really at your weight but i would leave the forks std.

dont you think that would give the bike a really high front end chopper feel and it would be a pig 2 turn and 110mm sag on a 5.2 spring thats a bit extream dont you think

not really as it's like the CRf and is a bit stinkbug

on the one I setup I put in a 6mm spacer which is 1mm more than the us version and at 100mm sag it was still stinkbug in feeling , 6mm in the shock is nearly 18mm at the wheel so it's 18mm lower than yours , the us one is 15mm lower than yours , don't ask me why ktm did this as I dint know

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey guys. I recently purchased a 16 yz250x and the first 2 rides i LOVED the suspension. Then the day before a race i reset all my clickers to stock and everything felt like crap. No plushness at all and deflected off everything. I now have a 5.4 shock spring for my 190 pound weight and dialed in sag. Any recommendations on where i should go from here? Right now the fork is 12 out on comp and 15 out on rebound. Shock is 1.75 turns out on hsc, 14 out on lsc, and 18 out on rebound. Any help would be appreciated!

      Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the  weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump.
      Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road.
      However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road.
      In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.
