YZ suspension adjusting???

Need help from those that have been there and done that.

I just picked up a 99YZ 250 and am trying to adjust the suspenison. For the forks, there are 2 screws. On is in the middle, and the book says it is rebound. There is a bi directional arrow with H and S for hard and soft. There is another screw in the corner, with no markings. What is this for?

Ive been lookin for the compression adjuster(is there a low and hi speed?) and i looked under the fork tubes, and there is something down there with the H and S markings, but it looks like a female bolt head. Is this it?

On the rear shock, i found the preload(no brainer) which i need to back off. I found the compression adjuster on the res, and the rebound on the bottom of the shock. Is there only one comp adjuster for the rear shock, or hi low?

This bike was set up by Precission Concepts for a 220# rider. Im 194#. It has different front and rear springs and internal valving, according to the previous owner.

Just trying to get it together by loosening the preload and compression. It rides a little stiff. I may have to buy lighter springs. Thanks all!!!!

Re: YZ suspension adjusting???

I'm not sure where the adjusters are BUT, try riding the bike a few more times before you change the springs OR go with a lighter fork oil? But your pretty close to the weight of the previous owner right?

All's I'm sayin is "YEA"

Eat 4 Big Macs morning, noon and night for a month and the suspension will be perfect for you. [img]/wwwthreads_images/icons/smile.gif[/img]

THE SCREW IN THE UPPER RIGHT HAND CORNER IS THE AIR BLEED SCREWW. UNDO IT AND IT WILL LET AIR ESCAPE that has gone by the seals. i do this every couple rides or so, just make sure there is no dirt in the area. i screwwed in the top adjuster 2 clicks for big jumps(80 ft table in my are) and one for reg riding.
the back i went in 2 up top and one on bottom , the rear wasn't botoming for me but the forks were. i am 175-180. stock suspension. 99 yz 250

for 00-01-02 they are three adjustments for each. two up top, one goes on the outside of the other on the top of the forks. imagine a bolt that had a screw in the middle of it. thats how the top of the forks are and the top adjuster on the shock. for 99 there are only two, compression on top and rebound on the bottom. or vice versa, 00' and on has hi and low speed compressionn hope this answers your question.

Re: YZ suspension adjusting???

i wouldnt adjust those clickers much more till you get a service manual and know where the stock settings are, from where the clickers are set at the factory is where the average rider would prefer them


they actually kinda set them in a compromise for all riders, so those setting will be ab out the best starteing point, Id adjust from there

Re: YZ suspension adjusting???

Welp heres what ive come up with so far.

Forks: zero compression, maximum rebound.

Rear shock, zero compression, added rebound, although i have not counted the clicks. I have backed off the preload. I could stand to back off some more.

This is with Precision Concepts springs set up for a 220# rider. I am about 194#rider.

I take it you didn't want to take chubby's advice on the Big Mac route huh!

When I was a child I caught a fleeting glimpse out of the corner of my eye.
