Default Quick Rear KONI adjustment question

I have some yellow Konis for the rear of my car. I have tried to start with full soft in order to ensure they are both adjusted correctly.

I have cranked it around a bunch of times. Is there a "Stop" to let you know when it's at the limits of adjustability? I can't seem to find one.

Thanks!

I've just purchased a set of Koni's for the back of my '83 also. They are the 26 1209 sport model. Yes, it has a button stop on these. I don't know which model of shock you have. There are several, and the are all a little different as far as adjusting. On mine, you must pull the plastic dust cover down off the top shock mount, in order to see the top of shock and that button. Go to Koni.com, and they have more adjustment procedures listed there for your particular model of shock.

I figured it out.... I needed to remove the bump rubber from inside first. Now I have one on full hard and the other on full soft. I am trying to back off on the one, but it's not budging.

I had to pull the foam rubber insert out before I could properly engage the forks when the shock was compressed. Sounds like you've got the same issue.

Steve - I'm assuming you're using these on a '44? I've found them best left in full-soft position for track use, unless you have an LSD or maybe little to no rear swaybar - otherwise you'll tend to get ugly wheelspin in the corners.

I am having a REAL HARD TIME with it now. One shock seems to behave ok and I can compress it OK to adjust. The other is full on stiff. I have to put my entire body weight on it and it takes like 2 min to compress to the point where I can adjust it. It rebounds like 20W50 oil on a 30 degree day - slooooow.

What have I done wrong?

Back it off again they usually recommend if you want full stiff to turn it till it stops and then turn it back about a 1/4 to 1/2 turn to make sure the valve dosnt completly close

That seems to be the problem - I can't make it back off. No matter what I do... nearly impossible to press in.

Yeah i had to put my entire body weight on it for a good 3 minuts for it to completly compress, if its on the car you could try using a jack to slowly compress the shock

Yes
but how do I fix it? I assume if I install it this way, I will have erratic performance!

A local friend suggested turning the top and trying to push it in, never got any better. I'm loath to do the job twice so they are sitting in the house until I can get a better idea of what to do....

They are a bit fickle but you have to remove the foam bump stops so the shock will compress fully put the shock in a vice or put it on the floor with another person keeping the bottome from sliping out and seriosly just put your weight on the shock untill it fully compresses, Then slowly turn the shock untill you feel the ajuster slip in, the shock will go down a little bit more. Now asuming you have it set to fully hard it wont be able to turn one way and will the other, Turn the shock the way it will turn about a half to a full turn and that will open the valve up. If you still cant get it i recommend calling the people you purched them from as they have i believe a unlimited warrenty or at least a very good one and its possible it needs to be revalved

I think the valve jammed shut. These are brand new out of the box.
Rubber stops were removed. I can press it in with my whole body weight and adjust to full soft. However, I'm concerned with putting it on the car where it won't compress properly.

My eperiance was that they were very hard to compress and made the car very firm yet are amazing on for autocross and light track events abet a little hard for the streat. If both shocks are the same i'd say put them on if not def call the retailer or koni directly. Good luck
