DRZ400 Rear shock adjustment

Just got a green DRZ400 and am in the process of trying to tune the suspension, found a lot of informative threads on set up. Problem is how do you access the rear shock to adjust it! From what I can see you have to take the sub-frame off. Any thoughts would be appreciated.

Just side cover (called side frame cover...)

You only need to remove the right side (exhaust) cover to adjust.
You will be able to see the adjusters beofre removing the side cover however.

Its a flat head screw inside a 6-sided nut.
The nut is the high speed adjuster, all in is hardest. stock is 1-1\4 out on 07.
The flat head screw is the low speed adjuster. Fully in hardest. stock is 10 out on 07.

Sorry meant spring adjustment

Thanks Hazza, do you know how to adjust the actual spring, when you take the exhaust side cover off I can just squeeze a punch in there but it's a bit of a drama to undo the lock nut?

Yep.

You can adjust sag by using a drift \ large flat head screwdriver.
Look between frame and shock gas cylinder. You will see two lock rings on top of spring. I recommend giving it a good spray \ soak and clean if you can especially if this is the first adjustment. Anyway top ring is the lock, turns counter to loosen. Loosen off a few mills above bottom ring. counter on bottom ring will loosen i.e increase race sag and turning clockwise will stiffen spring and reduce race sag.

If it wont budge

remove bottom linkage, remove linkage to shock bolt, remove top shock bolt.
Can do this easily with bike on stand, shock will drop out. Give a good spray and then scrub with brush to clean all the grime out of the spring threads, it will release, you may just have to give it a soak overnight.
