suspension suggestions for SM, 215lb rider, multiple terrains

Hey all;

Looking for some quick suggestions on suspension modification for my 05 DRZ-SM (suspension currently bone-stock).

I am 215lbs sans gear, and I ride in the following conditions...

1. Unloaded SM mode for fairly aggressive sport riding, general commuting, etc.

2. Dual-sport S mode with dirt wheels, medium-difficulty trails and dirt road exploring. Nothing super hard-core by many standards, but I'm getting better...and thus faster/harder in the dirt as I gather experience.

3. Fully loaded in either of the above 2 configurations for 7-10 day camping/adventure trips, usually about 40-50lbs of gear in the Wolfman bags.

I understand the stock suspension is good quality, but depending on weight/conditions, may need respringing/revalving. My SM suspension feels vastly stiffer than the stock "S" bike that I've ridden, so I don't really have a ton of complaints with it right away - though the rear end does sag a bit, and with some upcoming longer loaded tours this summer, I'm worried about overloading it.

I know this is a highly variable set of conditions to ask of suspension.

Any advice from those with similar experience would be most helpful. If it's best to just leave it stock, I can do that too!

Thanks all,


Thanks Chooken, I have looked through that site - the only info it gives is a spring rate calculator though, and I have no practical reference as to what they mean when they specify a particular riding style.

Which is why I was looking for some real-world experience and recommendations from anyone who is roughly my same weight/riding style/varied terrain, etc., and/or has lots of first-hand experience with DRZ-SM suspension tuning.


I'm in the same position

I have an 05 sm and weigh about cough cough225cough.

I am riding about 90% pavement right now.

Wish this snow would go away...

I'm 195 - 200lbs on an 08' SM. I notice it does just fine around town but took it through Baldy Mesa ( lots of hills, whoops and ruts ) area on the street tires and it seemed too soft. My background is strickly dirt / dual sport for many years and compared to other dirtbikes I've raced it does seem a bit sluggish in this department. I think anyone looking for better set-up ought to call people like race tech and get advice directly. A proper spring rate and valving ALWAYS does better than stock. My $.02 would be to call a few companies for pricing then go on the stiffer side of things as more weight will soften it up and stiff usually means more fun in my opinion. If you look around for videos and pics of stock SM's jumping they bottom out very easily with thier 400lbs. The more aggressive you get the more you'll find yourself going off bigger drops and jumps.

      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!
