FCR Carb Set up

I put an FCR on me bike it came with jets in it already...160 main...dunno what piolet but it came straight from khine..i am running a slip on...it stinks of petrol now and i get a lot of popping i havn't done the 3X3 think dunno how to...what should the jettine be in it anyone no?

what does the PAJdo? it says remove it..

Have you done the 3x3 mod? What pipe?

Yes, Paj is removed.

not done a 3x3 am running a laser pro duro...

Is that a full pipe?

You first need to do the 3x3 mod so jetting recommendations will be applicable.

The only firm advice anybody can give you is do the 3x3.

Until you tell us which FCR and what size, and the full jetting specs no one can do more than give a rough guess.

And as for the pilot air jet, well you may need to remove it, and you may not.

Depends on the FCR, i.e. which one, what size and how old.

Get a couple of pics of the carb and post them so we can see what one it is. The take float bowl off (4screws on the bottom of the carb) and see exactly what Main and Pilot Jet (main jet is the one in the middle and the pilot is just next to it, can also see them from removing the 17mm nut in the center of the float bowl) you have, also take the needle out and read the letters from the top of it so we know what needle you have (take the top off and undo the 4mm allen head in the middle top of the slide and carefully remove the needle).

If you have just a slip on exhaust and do the 3x3 theres about a million posts on jetting!!!


Did you try call me earlier Martin ??

I thought i'd answered all these questions last night.

Guess not :thumbsup:

hope this can help


What model FCR did you get? If it is a MX, you need to remove the slow air jet from the carb bell.

Also, did you put in an extended fuel screw? How many turns out?

Which pilot jet is in it?

What needle and clip position.

      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!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
