Trouble setting sag on my S

The locknut won't budge. I wacked it pretty good using a screwdriver/hammer and I'm just taking chunks out of the cog. I tried pounding the lower nut the opposite direction to maybe loosen/seperate it from the upper nut, no luck.

Anybody else have trouble with the rear shock/spring?

Just to make sure: to loosen the upper/lock nut, i'm aiming at the front of the shock; looking down from above the shock, I'm trying to turn it counter-clockwise.

Also, if I need say another .5 inch of sag, I need to "loosen" the upper nut .5 inch right? There will still be pre-load in the spring right?

Thanks for any and all help.

Try putting the bike on a stand tall enough to let the rear wheel hang, that should help with the preload. I use a special wrench, I think motion pro makes it


Me and a helper did mine a couple months ago.

I think one of the tricks is having somebody hold the bike from moving. In turn this will help get the power down on that nut. Also use a very large screw driver, or use a metal pole or some sort. Nothing with a sharp edge.

Lifting the bikes rear end off the ground(even just by raising it on it's kick stand to one side) will help ALOT.

I had the same problem. I just got a bigger screwdriver with a fatter blade on it. The smaller tips just dig in and the wider tips provides more surface area. Good luck!

Yep, it's all physic's.

Bigger surface area=larger transfer of force.

or something like that

The way I got mine loose was to tighten the bottom nut a little first. That should relieve the pressure on the retaining nut.

If you can find a brass drift, use that to loosen the nut. It won't tear it up as bad. I couldn't find one, so I got a length of about 3/8 in. brass rod at the hardware store and cut it about 12 in. long. Works really well, especially if you are lazy like me and haven't removed the little smog box yet. It will slip between the black box and the frame to loosen the nut for quick sag adjustments. Put the bike on a stand and make sure it's not sitting on the shock linkage when you do the adjustment as that puts pressure on the shock.

Thanks for the tips.

Now that I think about it, the bike was just on the kickstand, so I'll put it on a crate to reduce the pressure. I've been looking for a good excuse to buy a decent punch set, now I've got one :)

You don't need to move the nut .5 inches to change the sag by that much. There is a leverage thing going on between the shock and the swingarm. About .1 inch on the nut should do it.

Ride on

      So I am going to put in an in-line fuel filter just for added protection from stuff in my gas .... and I have always used bronze element cone ones you no what I’m talking about the ones everyone seems to use but upon reading online supposedly that bronze element breaks down and doesn’t catch everything .... I have came across a moose fuel filter that has a fine nylon mesh just like what’s on the petcock filter ... any opinions on which is better ? Bronze element or mesh ?

      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!
