Jeff from Illinois setting sag tool WR250R WR250X lowering

Jeff asks "I just purchased my used 2008 WR250x last night and was reading the manual trying to figure out how to set sag. Do I need a special wrench(s) to set the sag on these bikes ?"

Our reply:

Many use a long punch or old wide flat blade screwdriver + a good heavy
hammer (not a rubber mallet). Loosen the shock spring lock nut by hitting it
counterclockwise like any nut: right tighty, lefty loosey.

This gets the spring's lockring undone.

The easiest way to turn the shock spring up or down to adjust sag is by hand
but sometimes a bike is super crowded or the rider's forearms are too big to
fit anywhere near the spring to get a good grip near the bottom. Then you
have to use that long punch + hammer to beat, er, move the notched ring
below the lock ring and move it. Total pain often times.

It helps if the bike's rear shock threads are cleaned and maybe lubed to
help the shock lock nut and/or adjustment collar move up and down. One
complete revolution on the spring is about 2.5mm

Here is a refresher. They use long-travel MX bikes with 12" suspension but
the concept is the same: http://www.tootechracing.com/suspension_tips.htm
