replacing carb

I'm about to put a new stock carb on my bike and I was wondering if I need to put gas in it or anything before I put it on?

Nope, just bolt it up. If its used, make sure you go through it before bolting it up to save the hassle of having to remove it again. Once on you can put the fuel cock on prime for a minute to get fuel into the carb making stating a little easier.

Its used, and has a DJ jet kit already so when I go through it what am I looking for just dirty or broken parts?

Just dirt. I'd pull the jets and needle and just make sure they are clean. I recently helped a fellow TT'er jet his carb and his needle had varnish caked on from sitting too long. We were reusing the same needle but I'm glad I checked it because there was enough on there it would have affected how it ran. It only takes a couple minutes and will save you an hour if you have to do it later.

If you don't what jets are in it you should take the bowl off and make sure its jetted for your motors state of tune.

Cool thanks for the tip

If your talking about altitude its jetted for sea level and I'm at sea level and both bikes are S model

Do you have an open exhaust?

No stock exhaust

Was the other bike stock like yours? Stock cams and pipe? If so it's probably close but you should check to see if what's in it is what is recommended from JD or get advice here.

You say it has the Dynojet kit already?

The guy said that all he had was a 3x3 in the air box and a exhaust I pretty much drilled him on it being safe and affective on my bike and he said it'll work hes sellin for just 40 bucks so i dont think hes tryin to rip me off

I was thinking though since he had an exhaust I might need to do something with my stock muffler until I save up enough to buy an exhaust

Anyone got any advice on what to do with the stock muffler?


Oops, sorry I thought I read JD kit. Depending on what jets are in it and what kit it is S-stage 1 or SM-stage 2 if he had a pipe and you don't you may have to got to a smaller main jet. Give us some more details, what kind of pipe did he have, which kit, and what jets are in it now.

It depends on his exhaust. Usually just a different main jet is needed with an aftermarket open exhaust vs a stock exhaust. Did he send you the remaining parts from the jet kit?

I dont know what jets are in and its not here yet but I'm pretty sure its a stage 1 thats all I know for now. When it gets here is there any way to identify what jets are in it?

Yeah, just open it up and take a look. The jets are stamped with a number denoting their size.

Cool, I'll see whats in it when it gets here.

Alright I got the carb and it has a 132 I'm guessing main jet its the one over the needle, and a 62.5 is the next one down and the lowest is a 22.5. The clip is at the 4th position from the top.

I have stock everything right now and will be cutting a 3x3 if this might work.

Can I cut a 3x3 with these jets?

The main jet looks too small to me but I'm not that familiar with the Dynojet kit.

      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!
