DRZ 400 Rear Shock

Has anyone dismantled a 2000 DRZ400 rear shock? Am mechanically able to do job, just unsure of procedure. What weight of oil for shock? Have Nitrogen for re-gas, also have genuine service manual, not much help though. Any help appreciated.

Have a look in www.racetech.com

Following is a snipit from a pdf that I think came from there

Pm me fore the pdf

Instructions for 5016 Showa shock rebuild and valve installation:

Disassemble shock completely:

Remove spring:

-Spring removal can occur by loosening the preload washers on the shock body buy using

a soft drift to loosen the lock spanner and then hand turning the preloading ring. For

speed and ease we recommend that a spring compressor be used.

-After spring removal inspect shock for leaks and wear.

-Prepare the shock for easy cleaning and rebuilding by reducing compression and

rebound damping to full soft.

-Prior to bottom out cap removal, counter sink the removal holes. This prevents the edges

from being distorted.

-Using a large radiuses punch remove the seal cap by driving it off the body gently. Tap

from both sides to ease the strain.

-Remove the nitrogen charge.

-Using a seal head driver depress the seal head and expose the circlip

-Using an appropriate circlip remover remove the circlip.

-Remove the compression rod by gently rocking the assembly out of the body, and dump

the oil in the piston side of the body.

-Using a bladder driver press the bladder into the body far enough to expose the circlip.

–Remove the circlip and remove the bladder using a removal tool. Dump the oil in the

reservoir side of the body.

-Remove the adjuster using the Scotts removal tool. Many times on the RM models and

the DRZ have an AL spacer is placed behind the adjuster. Take care not to lose this piece.

Yes, I have,,,, several of them... It is doable,, But there are some basic things you need to understand.... The manual as you noticed is useless, as they consider it all one replacement part,, not to be worked on. :D

A Race tech vid is really usefull if you have never had the shock apart before,, better yet, a friend who has to walk you through it would be even better.. Where ya at?

You need not only the dry Nitrogen, but the correct high/low pressure regulator/gage/filling attachments to correctly fill a very low volume high pressure shock bladder. Most shops will charge the shock for a small fee.

Cheers guys, great help.

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!
