1994-2001 Yamaha YZ125 Rear Shock Rebuild Service Notes:
Do not use an air compressor to fill your shock; you have to use nitrogen. Air expands when heated, and the reservoir will explode.
This shock rebuild is fairly simple, but it is a messy process, so keep lots of towels handy.
There will be times when you use aggressive tools to rebuild your shock. You have to be careful not to damage the shock body, shaft, seal head, valve body, and shims. You will see what I mean later.
Your Yamaha YZ125 comes with a KYB shock, or Kayaba, if you want to be formal. If your shock is damaged beyond repair, you can pick up a used one for under $200.
You will need a vice. If you don’t have one, wood and clamps will do the job.
When you finish your rebuild, you will need to take your shock to a powersports shop to be filled with 165 psi of nitrogen.
