Suzuki DRZ400 3X3 mod

[BastardBiker]

I don't have a DRZ, but I might get one in a year or two. I really enjoyed the video though, it's very well done. People who take the time to visually illustrate these kinds of procedures are great. So thanks!

[EXPLORINGYouinHD]

DOES ANY 1 KNOW WHER I CAN GET THESE PARTS FROM

[suzuki06g]

@EXPLORINGYouinHD The parts needed for this mod (the DRZ400 3x3) can be purchased individually from a dealer or from ThumperTalk by purchasing either a DynoJet or JD jet kit for a DRZ400.

[jcbluefunk]

does the 3x 3 mod affect the bike's performance in wet weather ? 

[suzuki06g]

Just wanted to say that this is a great mod that applies to any DRZ400 that has a CV carb (later E, an all S and SM models). I did it and it really makes the bike run smoother as faster. It also the first motor mod that you should do, even before changing the muffler or head pipe. As those mods require different jetting anyways.

Excellent video rbrtplly!!!

[soheilrnr]

can i do the same thing for the drz400sm??thanks ;)

[hetisover]

What do you gain from this mod..

[kewinosss]

brum brrrum

[xninjazx6r]

LOL THUMBS UP IF U THINK HE SOUNDS LIKE CRAIG FROM SOUTHPARK

[ebayollis]

DOES ANYONE ELSE HAVE TROUBLE WITH THIS VIDEO?????

It will not play all the way through

[Blinky0Au]

some one correct me if im wrong but that whole does not look like it is a 3x3 hole cut by a 1.5" hole saw to me it looks like 2x3 which equals 6. please some one explain to me where the 3rd drill hole is because to me it looks like he has only drilled 2.

[imxz28]

Nicely documented... Very professional !!!

[itube4521]

why do you need both the pilot and main jet?isnt both provided in the dynojet kit?

[transoprtcontrols]

Will this adversely affect my mpg by much?

I'm thinking about doing this but not quite sure if it's for me. I go on REALLY long rides without ever seeing a gas pump.

[7h3647h32in6]

@transoprtcontrols You could always get a bigger fuel tank. It will affect your gas mileage, since it is essentially putting more of the air/fuel mixture into the motor. However, your mileage should still be around 50 with a 3x3 mod and rejet.

[racefactory900]

@7h3647h32in6 Keeping under 60mph on a cruise I get 70mpg with 3x3 mod, jetting and exhaust. You should get much more than 50... these bikes are awesome on fuel. I get 50 thrashing it.

[racefactory900]

@transoprtcontrols Keeping under 60mph on a cruise I get 70mpg with 3x3 mod, jetting and exhaust. You should get much more than 50... these bikes are awesome on fuel. I get 50 thrashing it.

[MyHairyChin]

Great vid but it would be so much cleaner and easier to cut the air vent with a dremal tool!

[paltalkdevil]

always better to put the bike on a dyno to make sure you getting best out of your jets and mods.

[bomberdebomber]

Why are you placing the E-clip on the 4th position of the needle?

Dynojet instructions says, it should be the 2nd position from above.

[bandguy360]

5:37 he fingered the carb

[SmR400]

hi nice vid.

one Q wat happens if the hole is a lilbit to BIG or 2 small ?

can the jets wait or is it part of the mod ?

[rbrtplly]

@SmR400 hole should be 3x3 to use the jets specified. Different hole different jets. DO NOT CUT THE HOLE WITHOUT CHANGING THE JETS!! If you do the bike will not run right. Go to thumpertalk fot more info on the right jets for you.

[buchey]

is there any use to cutting the hole, but not doing anything with the jets? I really don't want to mess with jets - but cutting a hole seems pretty simple.

[rbrtplly]

@buchey

DO NOT CUT THE HOLE WITHOUT CHANGING THE JETS!! If you do the bike will not run right. Go to thumpertalk fot more info on the right jets for you.

[pwnisher420]

@rbrtplly i did this with out jets had no prob, just no dirt riding

[EXPLORINGYouinHD]

where di u buy all this from ???

[TheZenerDiode]

@buchey more air without more fuel is pretty worthless wouldnt you think ;-)

[buchey]

is there any use to cutting the hole, but doing doing anything with the jets?

[Brakelateatmsn]

Thanks!

[Brakelateatmsn]

Thanks

[AK47PERFORMANCE]

Great video. Nicely done. That vacuum diaphragm looked a little stretched out, though. I replaced mine when it looked like that.

[rbrtplly]

@AK47PERFORMANCE

The bike only had 1200 miles on it, don't see how it could have been streached. Now it has 6000 and still running great.

[epicstove]

I don't want to pay for the jet kit, any chance you could tell me what needle you switched too? Thanks in advance for the info and the top notch vid...ride safe!!

[alanvb600]

@epicstove you can just buy the jets that are in the kit and raise the needle to the higest position, the main jet is £3 of a dealer or of a auction site (like $5 or sumthing) leave the pilot as it is and just go up main jet size. As you are using a filter and the same pilot jet you can just leave the mixture screw alone with its protective plug.

if you have a performance filter you go up to a bigger jet.

Dyno jet stickers are a £1 aswell.

[lollon82]

is all this needed to be done also on drz 400 E valenti?

[SmR400]

how did u get the jets on the carb with the original exhaust ? can u do that? wat happens if the 3x3 hole is a lilbit bigger than 3x3 ?

[andrew080387]

which benefits from?in hp??? XD sorry for my english

[Madiandgigi]

I like how im im the backgreound in some of the HAAHAAH

[ktnmouthkng714]

im so glad somebody took the time to do this step by step for everyone to see.

doing mine tomorrow

thanks man!

[carsnwomen91]

how about just removing the airbox and putting on a pod fiilter on the carb, retune? and by the way tuning a carb is bike specific, its a not generic/ or the optimum setting for everyone.

also u can just put a good flatslide in the lame cv carbs' place and slap on a pod filter and again, retune

[rbrtplly]

Yes, you are correct, but this following the 3x3 mod on a Suzuki DRZ400 as described on Thumpertalk. Go to the web site to get the correct jetting for you altitude.

[nitrojoe9]

nice vid. i wish i find something for this where they use the fcr carburetor

[touge2000]

There is a easier way to do this and

All I did was mark the hole I wanted to cut, heat the top of the airbox up with my sisters hair dryer and then just cut it with a sharp knife, cuts through the warm airbox like butter and it looks perfect with no mess.

[melardkey]

Nice instructional video, I'm gonna mod my DRZ.

You ought to buy a tripod for your camera.

[houseofcharm]

So now I find that my new-2-me klx has been jetted when they did the FMF. I want to do the fmf powerbomb to lengthen the exhaust pulse. Think more jetting will be needed? I should do the 3x3 at the same time and start from scratch on the jetting I think would be best...

[skating4ad]

if you do not drill and make the 3 turns out thing how does this effect performance?

[rbrtplly]

You can use the stock screw but it is hard to adjust. You may run real rich at an idle if you skip this step. I would get it, I adjust for cold and hot (seasons) since I ride year round.

[rbrtplly]

@skating4ad

3 turns is just a starting point, you back it down as far as you can with out affecting the idle. Mine is now at 2 1/2 to 2 3/4 turns out. Since you changed the Pilot jet you need to change the fule mixture to tune it right. Go to thumpertalk to get more info.

[skating4ad]

@rbrtplly

yea i understand what you are saying because i drilled it out and had it set at 2 and a half and it was way lean. i believe i have it at 3 and a half maybe 4 turns out now it it runs much better.

[houseofcharm]

Still, an FCR is a better upgrade?

[fiendsteer]

obviously . . .

[speedemon103]

I know this is a DA question but 3x3 thats 3 inches long and 3 inches wide right??

[q1s3d45g6]

Yes, 3 x 3 = 3 inches by 3 inches

[speedemon103]

If u drill the airbox do you have to rejet the carb or can that wait

[q1s3d45g6]

If you open up the airbox you need to rejet or your carb will be all messsed up

But you can change your exhaust without rejetting

[drtooth69]

NO, the bike will run like shit. You must rejet for the exhaust.

[IP1NKYI]

After you rejet do you HAVE to adjust the idle screw even if it idles at pretty much the right revs?

[fullboostturbo1]

Dont think so I have made my own power pipes for XR400 and the only thing I had to do to get it to run right was ajust the fuel mixture screw out about 2 turns MAX and I got atleast 25% increase in power at the back wheel, as my bike would not lift easy in 4 with a 13tooth sproket and standard exhuast, but with my power pipe I could lift it in 5th with a 15 tooth sprocket on front, I even had a Honda dealer interested in my powerpipes, but I was too lazy to do anything about it then. LOL Not now

[caseman86]

what effect does this mod have in the end ?!

im no bike-expert with lousy english skills, so it would be great if sum1 give me a serious answer.

cheers

[drtooth69]

Gives you about 4-5 more hp and better throttle response.

[VollgasHero]

really?

[rbrtplly]

YES, That is why I did it and made the video so everyone can do it.

[VollgasHero]

I think i was asking someone else something... but i like the video bro, it's helpful lol

[joshlinkhart]

Thank You for posting this video. It gives me the confidence to do it myself. Just orded everything I need.

[duggy191]

good vid but could you not simply buy a K&N airfilter n just rejet accordingly

[daboy233]

you forgot to tighten the frame! :p

thanks for the video

[q1s3d45g6]

So this is the DJ kit right? and not the JD kit?

[rmzrider151]

What does this mod do???

[StoneRiderM3]

my bro cut out the original airbox from da side, thinking it will makw more power with devil exoust ,

in fact it was rubbesh , i bought a new 1 and installed it heres a vidio

[chris187k]

Great vid, I am about to do this on my bike when my MRD comes in

[SleepsInBloods]

Thanks for the awesome vid guys. My mod turned out great. I have a stock header and a Leo Vince X3 Can/ Mid section Uncorked, so I used a 150 main and 25 pilot, needle on 3rd position, fuel mixture screw 2.5 turns out. Ripps like a champ. Gave me a bit more bottom and a lot on the top end. MEGA THUMBS UP GUYS!!!

thanks

[wot4edge540]

so did the dynojet kit come with the main and pilot jet?

and how is the bike running now? spluttering/ stalls/hesitant? anything like that or perfect?

thanks

[SleepsInBloods]

The Dyno kit only came with main jets, and a needle, had to buy the pilot jet separately. The bike runs awesome. shitload more power than what it had. I know for a fact that 150 is too high of a main jet for my carb, the float bowl will tend to get flooded if i cruise at a constant 30 or 40, but when im cruising the freeway at 80 its all good. All it takes is a couple good cracks of the throttle to flush it out when it floods like that tho. Other than that the bikes legit. best mod ever for drz.

[StuntRoni]

Hi!Good movie!I have a question:Keihin fcr 39 with 3x3 mod + Yoshimura RS3 exhaust and i have to rejet it.I only have to change the pilot jet and main jet?thanks

[flyboybill]

How big do you measure the hole out he goes now measure it out i know that saw circle I 2 inches but where do you drive the second and 3rd hole dont know, he has a wood piece but he never says how long it is to use it. I guess i will eye ball it.

[toker7117]

i jetted and did the 3x3 mod last year i have a 08 drz400s and it was worth the 2hrs to do it

[assapopulus1972]

what did you get out of this modification? and did you add a pipe along with it?

[assapopulus1972]

what did you get out of this modification? and did you add a pipe along with it?

[rbrtplly]

You gain 2 to 3 HP and you notice it right from the first ride. If I got a new bike this would be the first thing I would do to it. I did add a header later but it was no gain compaired to the 3x3 mod.

[assapopulus1972]

really no gain fromt the header? i live in northern california and do allot of hunting and fishing in national park, BLM.... and i dont want to disturb nature and or people when i ride in the parks, so this is good info for me ... spending 200+ on a header for what?? NOISE!?!?!? LOL LMAO

[konascrap888]

awesome video, can this be done to the off road model?

[flightestman]

ihave a 2009 dont know either but i am gong to do this, although i can see if you mess up the order of those carb parts and dont know how to do it you could fuck the whole thing up, and that drilling too he does it so easy dont be tricked this guy is a pro its much harder then that. Although it good to do it on your own if you fuck the whole thing up permanently you tried and trying is what counts here.

[gordotj]

the mod on my drz came out of the factory, i didn;t needed to make the hole i just remove the ruber kind of snorkle il put a video on youtube later

[engerer2008]

if you dont rejet the bike with this mod what will happen will it just keep cutting out

[pandamuffin]

Need your MCCT!

[TopNachhhhh]

how long did this take you? and isnt it a pain in the ass having to take all that shit apart again if you didnt do it right the fist time?

[markmindy]

thanks for the great how too.

[smoothcbr]

what a great how-to video. i cant stand the other ones that seem to skip severall steps cause they assume you should know what to do. simply a terrific how to video.

[alien0verlord]

I never thought "jetting" was this complicated. Thanks for clearing it up

[Georgenfla]

This is an excellent video. Very clear and concise. Good job man!

[mblendinger]

Hello! Just a question, this mod is applicable to the new DRZ400S 2009 ? or this issue was resolved from the factory on the new models ? can't found the size of airbox in later models to see if now it is bigger.... thank you!

[maxilong1]

dude you are effing amazing, i was wondering how i was about to try to do this without much mechanical experience, this was so helpful, thanks a million

[jim6504]

Great video, just done the 3by3 hole, but got origanal jets, and a rase can just put on, will the jets make it go better, cos now it's not runing right, cheers for the video again

[jbwiden]

It will run lean if you just make the airbox hole larger. Get a jet kit(jd is considered the best) and then remove tape.

[jbwiden]

I meant to say cover the hole back to original size with tape and when jetting completed remove tape

[rbrtplly]

YES, Cover the hole back up with duct tape to about the original size until you get the correct jets and jet kit. You are now running lean and could do some engine damage.

[KanzlerM]

The jet kit makes a huge difference.

Be careful - until you re-jet your carb you are running super lean after the 3x3 - your bike will run much hotter.

The bikes already run lean when stock to pass EPA reqts; 3x3 w/o re-jetting makes them even worse.

[Duedog]

Wow...thank you so much. This video made the whole experience a million times better than it would have likely been.

Cheers!

[STUARTHAGERMAN]

Thank you very much for the video. It helped me out.

[jcdenton7]

Excellent video! This is probably the most informative video I've seen on here. I don't own a DR-Z400, but I do own an XT 225. I had to do the same thing with the plug covering the fuel mixture screw on my bike. 3 turns out is what I'm at, and it works magnificently.

[Jason85rida]

same for the drz 400 E? thanks

[robrobrobrob888]

lovely thanks!

[0i0overload0i0]

i got a crf150r. i got a rocket slip on and i was going to do a R&D power bowl to take awey the bop

[Xmoto16]

narrator guy sounds like the ape from my gym partners a monkey.lol right but seriously nice job

[Chonchachencho]

lol... oh

[Chonchachencho]

what is your elevation?

[rbrtplly]

I am at 100 - 200 Feet.

[neznarftruk1]

after i do this, will i have to continue to mess w/ the jetting?

[rbrtplly]

If you go to the web site to get the proper jets for your altidude and other mods you already have should be ok. Go to the forum and select the suzuki drz400 and search 3x3 mod you should find all the info you need. It is all free.

[robincx]

I've been looking for exactly this. Thanks so much! My Yoshi and JD jet kit arrive next week, I'm stoked to have a tutor available.

Thanks, great job!

[robincx]

Just did it. I tried without removing the carb, but it became apparent that with the float bowl screws being so tight you have to pull it out. I did not need to unhinge the frame, just release the throttle cables and loosen the gaskets. It will come out with a little convincing.

[byrneiboy]

Is this exactly the same for a 'sm' with a full yoshi?

[rbrtplly]

The jet kit may be different but the procedure is the same.

If you go to the web site to get the proper jets for your altidude and other mods you already have should be ok. Go to the forum and select the suzuki drz400 and search 3x3 mod you should find all the info you need. It is all free.

[nigel182]

Thanks for the nice tutorial. I brought my laptop in my garage and followed along. It worked great!

[1096919]

Nice job guys. Great video!

[Chthon128]

I ride mine primarily for gas mileage--does anyone know how this affects gas mileage? I don't do much offroading with it--got an Enduro RMX250 for that--but is that the primary reason for this mod?

[rbrtplly]

It will lower your gas mileage simply because it will have much more power and it is fun. You will find youself riding wheelies all over. I get 50 to 55 mpg depending on how hard I ride.

[Chthon128]

Thanks for that info, robert!

Looks interesting, but my RMX pulls wheelies already like a bucking bronco! I think I'll keep my 70 mpg!

Thanks again!! :)

[attuco]

I'll give it a try now that you've made it look so easy.. thank

[rbrtplly]

You will not regret it.

Just so you know there as about 20 minutes of getting the carb out an in, that I edited out. It may take you that long as well, so don't get too frustrated.

[touge2000]

Great video!!

[dreadhead13]

FYI the "pin" is actually called the Jet needle. good vid though!

[Goktendal]

Thank you very much. Everybody was talking about jetting, but that stuff was a total mystery for me untill I saw this video. Great job.

[bag2008]

good work.....

[Turppa21]

And can you notice a power difference?

[rbrtplly]

YES, It is a big differance. The best $85 you can spend on a DRZ400s. You can make the hole a simple 3x3 hole but I wanted to make mine look nice.

[Turppa21]

it looks like a lot of finicky work. How much HP do you gain?

[rbrtplly]

You gain about 2 to 3 HP about 8% gain, you feel it!

[Eppe100]

you gain that much just from the 3x3 hole? Or is that with the jets and everything? Can you feel the difference just with the 3x3 hole?

[gerzoym]

πουτανα το εκανε ο μαλακας.ελληνοπουλα μην τον εμπιστευεστε...για το πουτσο ειναι

[edwards22b]

y cant yanks pronounce the names off japanese makes of cars and bikes??

[benjenings]

please dont call us yanks..we pronounce it the same as the japanese..lol..but im from the us and this guy talks differently from me..

[FIFTYPIMP]

great video!!

[07drz]

doesnt seem near as hard after watching this.....thanx

[hudsonslim]

very very much appreciated!

[drz400sm1]

nice, great video. wish this would have been out a couple years ago!

[tylo604]

Great video! Really appreciate all the time you put into documenting the process!

[floatch]

This is awesome. Just hearing about this mod makes it seem tough, but seeing it done makes it all seem so simple! THANKS!

[okemos1]

It's about time. Tons of guys will want to see this.
