I started a thread about this but I wasn't as clear as I should have been. I have a 15 sm and just got some dirt wheels for it, what is the biggest rear sprocket I can put on with the stock chain and the 15 tooth stock sprocket? My goal is to be able to have decent gearing off road and be able to swap to the sm wheels without swapping chains or front sprockets.

The guidelines you present, (15 counter and stock chain) limit what you can do for "decent" off-road gearing.  15/44 I would guess.  That is stock S gearing. To get equivalent to 14/47 (stock E gearing) you need 15/50 which will not work with a stock chain.

Would I be able to run the sm gearing with a longer chain? I don't mind having to buy a longer chain to make a better set up work, I was just trying to avoid changing it every time I swap wheels

I run 15/47 with a 112-link chain. Could probably fit a 48 on the rear but haven't tried it.

I took a 49 off my bike (2001e) last week, 15 front and standard chain

thats pushing it and the chain was likely stretched if that worked .. pretty much you need a 114 for that and for the original poster thats a decent dirt setup, you just need a second chain .. you could do a 14 counter and 44 in the rear to use the same chain as your sm setup most likely but imo playing around with switching counters all the time on the drz is bad juju ...

That's probably what I will go with, the 112 link chain and the 47 tooth rear. I want to make swapping rear wheels as easy and fast as possible. 15-47 will still be a bit tall but will have to do! Thanks for the help guys!

I run 14-41 on my SM wheels since I no longer have to go above 50 on any of my rides. And when dirt wheels are on it run 14-44

That is what I will probably run, do you think with a 112 link chain there is enough adjustment to run the stock rear sprocket, or do you have to go to the 44 rear ?

A 112-link chain is too long for 15/41.

      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!
