Changing jets was easy (lying).........

Just did the re-jet for my '06-S.

- had to remove the exhaust to be able to rotate the carb enough

- had to easy out (2) float bowl screws

- lost the little o-ring at the top of the carb (substituted an o-ring from Lowes)

- didn't plug the vaccum hose in and pulled my hair out for 15 minutes (erratic running)

All that took 2.5 hours.

- Opened up the top of the air box to 3.25 x 4.25

- cut out pipe restrictor

- JD jet kit (160/25/red neddle on 4th clip)

The thing is, I now have a louder decel pop, and a irregular hanging idle.

- I will check the throttle cable angle tube, but I think it's the Lowe's o-ring that is doing it: it was just slightly to large in diameter to fit in the recess. There is an audible pppffftt-ppppfftt in time with the motor, but I can't tell where it is coming from and am assuming it is the oring.

The bike is obvioulsy faster, and has better throttle response, and has a much louder intake honk.


Should have taken the carb out instead of pulling the exhaust. That way you get it on a nice clean work bench and aren't likely to loose parts. That and it takes less time. About an hour out and back in on my first attempt, not including the break in the middle to grill up a couple of steaks. Twenty minutes total the second time to try some different settings. Realy, it isn't as hard as it sounds to pull the carb.

Krannie, you did it the hard way. :thumbsup:

Tape the airbox hole down to 3 inches by 3 inches exactly and try it. Your jetting presumes 9 square inches so this might be all it needs?

yep pull carb 40 mins frsit time now i can get it out and back in in about 20 mins with a bit of time to stuff around and fix whatever and have a beer :thumbsup:

its not the doesnt seal anything.

where did you set the fuel screw?

:thumbsup: :thumbsup: :busted:

I echo this comment. Probably should do it before going any further.

Probably the sound of air going into your airbox. It makes a much nicer sound than stock when the hole is at 3x3.

      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!
