today i installed a gold valve kit in the rear shock of my 2003 cr250. while trying to loosen the nut holding the valving and piston onto the shock rod the base where the rebound adjuster is came loose. i tightened it up and carried on. now that its all back together when riding the rebound seams like its all spring it compreses fine then comes up and bounces. what did i do and what do i look for in that bottom cap to fix it?
what have i done?!?

Do you mean the clevis (the bit that threads onto the shaft and attaches to the linkage) came loose on the shock shaft ? if so you haven't screwed the shaft into the clevis enough so even when you clickers are maxed out your rebound needle doesn't move up enough to effect the damping.

To check the shaft isnt binding up half way into the clevis, measure the depth of thread in the clevis then measure the same length on to the shaft and wrap some tape or mark with a pen where this height is. Then simply wind the shaft into the clevis and check if when i goes tight is when it runs out off thread.

Its not that its running out of threads it definitely stopped when the clevis came into contact with the base of the shock shaft but I will check it out just incase

When I look at the clevis and the nut on the bottom of the shaft they don't seam to be at the same angle I'm going to take it right apart and mark Om both halfs where they line up straight and locktite it there

Also how important in nitrogen pressure for the valving to do it's job? My shop with the right nitrogen pressure was closed and locked up till Monday so I just used a tire shop with nitrogen there gauge ended at 50psi so I told them to open it as far as it went and called it good till monday

50 psi should be enough just to test if it all works, sounds like something might be cross threaded down by the clevis which would explain not being able to wind it in far enough

The larger looking openings on the gold valve are meant to face the compression stack (stack on the bottom)

I can't believe myself! I put my rebound stack in upside down! It works so much better nOw for some weird reason

If you want to feel even better I'm one of only a couple people in my city and province who rebuild shocks. And I do a set a month for work. However they are sled shocks
