Default '00 CR250 Compression adjuster never bottoms out

     

I bought a 2000 CR250 that was in good shape and starting going through it. I was given a manual with it so I readjusted compression/rebound on the forks and shock back to stock settings.

Everything went fine, but the compression (top adjuster, the adjuster that clicks that you use a flathead on) on the shock never hits an end point like the rest did. I can feel the adjuster clicking and it feels normal, but it never reaches a stopping point. It doesn't stop turning it in or out. The shock rebound adjuster had 24 clicks so I slowly went through 20 or so clicks trying to turn it all the way in and never found it stop. I also didn't notice any change in the shock compression after adjusting it. All in all the suspension works well and seems fine for me.

Anyone ever run into this or know whats up? Did the previous owner turn it too hard and break the adjuster past the stop point?

Thanks for your responses!
Dan

I would suggest having the shock gone through. First - who knows how long it's been since the fluid was changed. Second - there is no mechanical explanation for the screw not to bottom out or top out - somethings fishy with that.

I have rebuilt numerous shocks, so I am familiar with that adjuster mechanism, and I can not come up with a scenerio that would explain what is going on with your adjuster - unless your compression valving is totally cooked. Even then, the adjuster should top out. If the screw is run in far enough, it will basically run out of thread and simply spin - but not in the reverse direction.

Have the shock gone through. That's my advice.

Scott,

Thanks for your reply and information on the mechanics of the shock. The previous owner said he had both shock and forks redone just a couple months before selling the bike. He produced a receipt showing the work done and it was like $400. The suspension does seem to have been reworked. No seals are leaking.

Perhaps the adjuster is just stripped. One would think the shop that worked on this would have repaired that or let someone know.

infor,my forum is right under yours and all my screws top and bottom spin freely.not having equal settings blew out my seals i believe.i pulled the top bolt off my forks(the big hex)that has the adjustment screw.the screw on top has a slot cut out of the center.the needle(inside the fork) has a rectangular top that slides in the bottom of the screw.thus making it turn when you twist the screw.on mine the screw broke on the inside so the screw would spin but not the needle so there is know effect on the adjustment.i have to do the bottoms to it will be next week so i will keep you posted.hope this helps.

Wow. Well - perhaps the shop that did the work could shed some light on the problem.

I am interested to know how this could happen.

Your adjuster may be a style that has an inner plate with numerous bleed holes drilled around its circumference. By turning the screw it may just be coming back around to it's starting point again. If the suspension is working well and there are no issues with compression or rebound damping I wouldn't worry about it to much.

Thanks for your reply. I am not sure, but hopefully that is the case! It seems fine to me. I'll just ride it!
