Suspension Mods

Where to start, I'm a six foot 205lb. rider and i can't stand the stock susp. i bottom out all the time and my back is taking a beating...Should i just start with stiffer springs or what...Set the sag on the rear end which helped but the forks are taking a thrashing when i ride...We rode bear creek at lake greeson(Arkansas) this last weekend flash flood rain and all...

maybe a revalve, or you could go the whole nine yards and get a turely incredible suspension....but that will cost ya

Send your suspension to Scotts' and be done with it. About $450.00 for springs and revalve ( total for front and rear). The best $450.00 you could spend on the DRZ. $450.00 in suspensin work will help your riding a lot more than $450.00 in motor work. :)

I just mentioned Scotts' off the top of my head I use Hitchcock Industries in Englewood Colorado (suspension man from A-Loop Off-Road)

Race Tech, WER etc. are all good, the point is just do it, do it, do it. If you think the DRZ is fun now wait till you have the suspension done. You'll be surprise as to how fast you can ride through the trees and over the rocks, rutted down hills no sweat. Have fun and ride like you're breaking wind. Oops, I mean ride like the wind.

DRZ Suspension,

Good topic!

The DRZ has excellent components, they are just set up really soft.

We are talking a Conventional 49mm Showa fork with a 28mm cartridge and 28mm base valve, with a 12mm piston rod. Top notch components!!

The fork is set up with a check plate instead of a shim stack on the compression side of the midvalve piston (active valving). Once you install a real shim stack here, this improves bottoming resistence dramatically.

Once you sort out the active valving and the passive valving(base valve), install the proper fork springs (get rid of the progressive springs)and you figure in the flex benefit of the conventional fork design, you have an excellent offroad fork!!

The shock is a 50mm Showa unit. The one item that I beleive needs to be addressed is to have the shock body hard coated. It comes stock uncoated, the untreated aluminum oxidizes and contaminates the shock fluid very quickly. (rub your finger across freshly polished aluminum and see the black oxidation, imagine that being your shock fluid. When the body is "hard coated" a coating of T3 teflon is impregnated into the aluminum body.

Also without the hard coating, the bore of the body will wear sooner. The process is only about 75.00, it is cheap insurance for the body of the shock.

The shock has a 5.4 spring which is good for a 180-190# rider.

I have seen articles in the mags where they throw 4 grand worth of Ohlins suspension on the DRZ, not needed, this bike has great components IMHO!!

Take Care, John

john, sounds like you really know your suspensions. so here is my question for you: technically how does the S vary from what you described (which i assumed was a E) if i weigh 135lbs, and i have the stock S suspension, where is my money best spent? the springs don't seem to stiff, they actually feel ok to my untrained butt.


What year "S" model do you have?

I beleive the '02 models came with similar suspension components to the offroad only models.

Take care, John

you could also change the stock fork oil , add a heavier oil, or you can try to add some 5W fork oil to the stock setup to lessen bottoming, also have you adjusted the bottom (compression)clickers.

I am 200Lb, i flushed the oil with 5W, set oil level to 4 inch from the top (with spring out), and happy with the front susp.

do a search on front fork , you will find all kinds of goodies.

Before you spend $$$.


The "S" model('00-'01) to the best of ny knowledge has damper rod style forks. The emulator valve made by race tech is a good modification to the damper rod style forks.

They quite easy to install and do provide additional damping for your forks.

**Very cool looking S model!!!

The installation is pretty basic.

1.Take the fork cap off

2.Remove spring

3.Drop in emulator

4.Put spring back in, tighten fork cap

5.Ride :):D

** Read instructions first, there is some minor adjustments(according to the rider preference) to the emulator before installation.

The adjustment is limited to the preload adjustment. I would just check the sag (95mm reccomended).

Take Care, John

I took the easy way out and sent it to a company here in California called RG3. They know alot more about this than I do, did a great job, and they are just good people. You might want to give them a call and let them dial it in. It is worth the money.


thanks. and i just added this little bracket after offing a signal:

so john, if i can bug you once more, i feel i am fairly adept mechanically, but i have never done any fork/suspension (or other hydraulic) work myself. should i put the emulators in myself? do i need to do anything to the shock to compensate?

      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!
