Suzuki DR-Z400 3x3 Mod (High Definition)

- While helpful, I was disappointed in the quality of the videos covering this popular mod for the Suzuki DR-Z400, so I decided I'd make a higher resolution video for future tinkerers like myself.
The bike picked up significant mid-range power with this mod. Stock I couldn't even clutch up second gear and do a wheelie and now it comes right up. - Авто та транспорт
Doing this mod, along with a full performance exhaust and jet kit, really gave my Drz400 a good boost in power. The power increase is very noticeable, and the throttle response is much better now too.
I would definitely recommend this mod. Just keep in mind, you can expect the need for more frequent oil changes with the larger intake hole on airbox.
What does that have to do with it?
Just bought a used DRZ it had the 3x3 mod done to it I just noticed. No clue if it’s been rejetted though. Any idea easiest way to find that out? The previous owner didn’t do it so he doesn’t know. And it’s completely stock besides that. Seems to ride fine too
@@jake2772Is the exhaust popping/back firing at all when letting off the throttle and decelerating? You will need to remove the carburetor and check what size jets you currently have installed.
I couldn't remember what the stock jet sizes were, but I looked it up for you.
Stock jetting for Mikuni BSR carburetor found on DRZ400 S/SM models
Main Jet: 142.5
Air Jet: 62.5
Pilot Jet: 22.5
@@markalan4026 awesome thank you and no popping/ back firing on decel. Dumb question the numbers you provided will those be written on anything showing that?
@@jake2772 Not a problem, glad to help. The numbers will be written on the individual brass jets themselves, inside the carburetor. You will need to remove the carburetor float bowl in order to access the jets.
On the DRZ400 the carburetor is really crammed in there tight, it can be frustrating removing it from the bike if you haven't done it before, so take your time with it.
There are several how to videos here on UA-cam, I would recommend watching a couple and following along.
A simple video with good camera angles and no stupid bloody music like so many others do. Thankyou very enjoyable.
No techno/dance music and just silence is refreshing.
Bloody!!!!!! It'll be Blooooooody!!!!
Wish he would get tripod. Drives me nuts watching somebody use one hand to work on something.
@@vynleshmynle7372 He uses 2 hands a lot in this video. Did you even watch it before commenting?
Yes, and no bloody music which is so unnecessary. 👍
I don't even have a DRZ an I'm watching. Thanks
me too.. :)
I don’t have either... yet lol 😂 I’m thinking about buying one though , there seems to be a lot of modifications necessary to get the bike up to speed . I sure wish Suzuki would just just give it fuel injection. And a 6 speed transmission, and a diet to get the weight down.
hahaha same here!!
JollyBruin 4570 they can’t it would never pass modern day emissions and the new one would be less powerful
You guys need one. No regrets

I just bought a DRZ with this mod already done. Now I can comfortably sleep knowing how much work I won't have to do. Thanks
About to buy my first bike on friday and am doing the same thing here lmao
now you just have to sleep wondering if the mod was actually done or not...
@@WhiteGravey lol
@@WhiteGravey 😂 that's fucked up
when i bought mine the guy had already done it
but i don't think he rejetted
what are some symptoms of not rejetting?
This man knows how to work a set of vise grips!
Good video. The only thing I can suggest to you, or anyone else working on Japanese bikes - get a good set of JIS screwdrivers. The fasteners on our bikes aren't Phillips like they might seem at first glance, but rather JIS (Japanese Industrial Standard). This was something an old motorcycle mechanic taught me 20 years ago, and I quit stripping screws on these bikes since then.
Thanks man, I wasn't aware of JIS, you taught me something new today.
AKJeeper Absolutely! I was going to make the same comment. I bought some great Vessel screwdrivers that have a hex section so that you can use a wrench on them if the screws are tight (
www.vesseltools.com/handtools/screwdrivers/megadora/930-kit-p123-detail). They work like a charm. Using Phillips screwdrivers on JIS fasteners or on Pozidrive (found on Brit bikes) just chews up the heads and ruins your screwdriver as well, although Philips screwdrivers are junk to begin with, so no real loss there.
Had a tech teach me the same thing. Many years of unnecessary struggle.
good point!
Peter Eastwood thank you for sharing that link , I just ordered the 8 piece ‘motorcycle repair kit’ $96 but excellent quality tools and worth every penny just to save yourself the headaches and frustration alone by using the proper tools .
Such a pleasure to watch this! Superb camera focus, great angles, no hideous music, no inane mumbling or eye-rolling “vlogger” type voice over. Good heavens this was soul soothing, hahaha!
Yesterday I followed your steps in this video on my 2018 Suzuki DRZ400sm and yes it was worth it 100%
Running good?
Why?
THANK YOU !!! This was a great vid. Also thank AJ Keeper for the info about the JIS phillips drivers, been a mechanic all my life (62) and didnt know that, will order a set tonight.
Holy cow this video is incredible, thanks for using a HD camera and tripod - so much easier to watch. I just had to clean out a clogged jet on my carb and did everything the absolute hardest way. I would have saved so much headache if I would have simply loosened the subframe not tried to pull off that entire rubbery air box thing. That nearly killed me.
Nice vid! Clear visual instructions/walk threw. Well done! There needs to be more vids out there like this.
Great video man! Looking at doing this mod with the mrd exhaust very soon. Lots of videos out there but seeing it done step by step will help alot more. And thanks to some of the replies for little tips and tricks.
Brilliant video! I was fascinated till the very end! Precise, simple, clean... Thank you.
One of the best break down how to videos, not just bikes, but period, short, not talk, to the point, love the bullet proof drz400(with manual cam tensioner)... Not a 450 but the hop on start and reliability part beats a 450.
5:22 a little note on the float bowl screws (stripped in the video), they strip because people are using philips screwdrivers on them when they are actually JIS screws (Japanese industrial standard). They are similar to philips but ever so slightly different. It doesn't help that they are put on TIGHT when stock and they are made of the softest metal known to mankind.... Anyway, I was able to get mine off without stripping when applying a ton of downward pressure and using a JIS screw driver.
This is a brilliantly done how-to! Thanks very much!
Glad I was able to help.
thanks man you helped me out so much cause i could see what ur doing very clear. So many times people skip steps or do something in a bad angle and i just have no clue what they did
I think this is the best tutorial out there for this.
I have watched and watched again your excellent video for tips on removing the carb and the jetting,my (UK) SM is 15yrs old and the carb has never been apart now its off the bike those float bowl screws are giving me nightmares lol.
Cheers for posting helped me greatly.
Thank you for doing this video! Planning to do it over the winter but as you said others videos were so/ so. Cheers!
I just completed the mod. Everything was pretty much the way you showed it except getting the carb back in and seating it in the airbox hose was difficult. I finally got it in after coating the housing hose with some oil.
Well worth it though. That first test ride was a wheelie fest.
Best DRZ 3x3/rejet vid on the webz.
Gracias por el vídeo. Muy bueno.
Thanks for the video, definitely helped with my install.
Pro Cycle sells these carb kits for the 400 and 650 and with air box mod and exhaust can get you a real 10% hp increase and make them run so much better thru the whole range.
Your video helped tremendously thanks so much! 💪🏻💪🏻
Excellent!!!! Awesome job, thank you!
Cuban Rider, great video best I've seen!! Question what was the tape for towards the end or did I miss something.
Those bottom bowl bolts can be a pain ... I like the technique you used I stripped one and used an easy out lol
Even though this is a bit old, it helped me greatly, good clear video, thanks.!!!
Great video thanks. Very neat way of cutting the airbox too. I take it wheelies are way easier! Looking forward to doing mine!
Wow,AWESOME VIDEO Cuban Rider!!! I learned MORE in this "how-to" video,than I have,watching OTHER "how-to" videos,where most of it,is the moron TALKING through the entire thing,and muddying up the screen with "text" every minute or so,explaining what their doing (even though the guy is verbally SAYING IT at the same time!!!) But YOURS was GENIUS!!! As it was all "action" in showing precisely what it was You were doing,instead of listening to it!!! Awesome job man,and glad the mods made a difference!!! ;)
Great vid. Thanks a million
Helped a lot. Much apreciated.
Your bike is oddly pristine
Great video nice camera work and how to. Thank you
very, very good video, thanks! Cuban Rider
Nicely filmed Mate! Precise and simple. Too bad I don't have one to play with...
Thanks Nic!
Excellent Video :)

Do i need an aftermarket exhaust if I'm doing the 3x3 mod? I bought a JD Jetkit for my new DRZ 400s to get more power out of it. Just wondering if re jetting will help without modifying the airbox or having an aftermarket exhaust. Great video man!
Super awesome video. Thanks for sharing
This worked so good. A carpet knife cut like it was butter
im glad mine already had this done when i bought it, for a 20 year old bike its amazing!
Good video my mate but what were you drilling at the end of carb mod..? Did you just wind it out as instructions say ?
Great video brother! how long did it take you to do this mod? and how skilled of a mechanic are you 1-5 5 being the best ?? lmaooo that way I know it might take my ass twice as much time
Finally good res video of this
Great video ! we work on DRZ's around 80% of them have the 3x3 mod.. More air more fuel more power.
Reliability? More dirt into the engine, more engine wear?
@@darthorpheus if there's a good filter then no dirt will get inside the engine. Maybe the filter will get dirtier sooner because of this but just maybe
I see that you edited out the facial expressions and things you blurted out right before using the vice grips to nibble out the tight screw..you are excellent and a professional..good video.keep it up
Fantastic video.
Très intéressant, merci 👏🏻👏🏻👍🏻
Very nice! Luciano and I are both looking at getting DRZ400s for dualsporting. He’s on a KLR now and I’m on the Multi, both on TKC80S but limited compared to a lighter bike. Trails we take that are stressful on the big bikes are a joy on my CRF230F, hoping the DRZ lets us get to the trails with ease and handle the off-road better than the big Adventure bikes.
That's awesome, I've been seeing your pictures on FB, definitely jealous and something I'd like to do in the future. The DRZ is great due to its lightness and extensive aftermarket, they can be found fairly cheap too. I sold mine earlier this year and miss it for sure.
Great video, thanks. The stock against works ok with this mod. Not convinced it’s necessary to upgrade it. I wonder why Suzuki strangle the bike with the small air intake snorkel in the first place…
Did you upgrade the exhaust too with this mod or just 3x3 and jet kit?
if you dont mind what jet kit did you purchase looking to do this same mod to mine as well
To compensate the extra air intake you should get a less restrictive exhaust
is that the ecu under the seat? doesnt it kind of eliminate some of the effect of the 3x3 by it being mounted back over the hole?
hi and thanks for top quality video. is this the FCR 39 CARB or the CV carb? thanks
No, this is a rejet and the 3x3 mod. You would need to do the 3x3 if you get the fcr though.
I am getting my first drz in 2 weeks! I have been working on Honda’s for years and I could tell just by you turning screws that hondas are so much better quality! Your video was such high quality that I could tell a major difference. Thank you for the video i am sure I will be doing this on the drz once I get it I’ve wanted one for some time now!
My first mod was to remove that horrid strap across the seat.
Excellent!
This video is good. I do like more of the step by step better. But over all good vid. When i get my bike i will watch this and have to stop the vid every move you make. But it is what it is.
great video!
Reminded me of one of tbose space movies wigh all the silent scenes... Do like the grey colour sceme on the DRZ.
Do i have to do the jetting if i put yoshirma rs2 exhaust and if so do you think dealerships mechanic would do it thanks
if the DR-Z i'm going to buy has the keihin 39 already (DRZ S), is so important this mod to have an easy-good-wheelies-bike? it increase more the high-end power or the low-end torque? thanks
Never fails! Every new bike needs mods?
Does everyone take paint off the frame while removing the carburetor. Is it that tight all the time. what would be the longer route avoiding that?
Thanks for the video
What happens if you jet the carb but don’t do the air box mod? I recently sent my drz in for its first service (600 miles) and while it was there I told them to jet the carb and put a new full yoshi exhaust system on the bike. I don’t know if they did the air box mod and my bike seems to be running a little strange since they did the mods. While riding around 60 mph the bike just shut off and sometimes when I twist the throttle I feel I don’t get an immediate response. Would the airbox feed the system enough air to make it run correctly if the airbox mod wasn’t done after they put the jet kit in? Any info would help. Thanks in advance!
What happens if you forget to put the little spring in the slide?
how long did it take to force the carb back in? 2-3 weeks?
So im just getting into motorcycles and I plan on getting the drz so what did he just do?
Do you know maybe an impact on fuel consumption? Is it smth like 20% increase?
It looks like you left the rubber boot in the carburetor off on one side. Why?
Which DRZ is this for ? I have an E . Different carb right ?
was something broke or in need of fixing?
Is there substantial benefit to 3x3 mod with FCR39?
Looks like you did everything but add a longer air/fuel adjusting screw 👍 nice
After watching this it brings back memories when I did mine in 2009. I remember cussing a lot more than you. Hahaha. And I received bent needles which pissed me off. I had to install the richer setting and would over fuel when putting around. But yeah, it absolutely hauled afterwards. Now time for the Athena Bigbore and +4 stroker crank. 😈
Que Bola amigo! Mi padre es de Mantazas Cuba! Your DRZ is so clean, mine looks strait clapped lol. How did you like the 3x3 mod?
Gracias hermano. Eso fue cuando la DRZ estaba nueva. La termine vendiendo a finales del verano pasado ya con más de 4500 millas. El 3x3 funciona perfecto, le da un poco mas de torque que era lo que estaba buscando para levantar gomas. Saludos!
so question why not just put an open airflow filter instead of putting a hole in the air box of th bike?
Hello Cuban Rider, from spain, ya tu sabe :)
My thing is: Im getting soon the Full system of Yoshimura Exhaust RS-2. And I want to know if should I do that mod to my drz 400 sm 2008. Some people told me I should "recarburate" it, change the air filter to the "K&N", and told me I should take a kit of carburation. I have the stock carburator, Mikuni, same of yours.
Hope u can help me and recomend me what I should do, because I'm pretty lost right know.
Sick quality of vide tutorial btw !!
Thanks man. I don't have a ton of experience with carburetors (ironic, since where I grew up everything was carbureted), but the re-jetting kits come with different mains that you can swap out depending on your mods. For me it's a 155 main jet since the bike has the stock exhaust and close to sea level, but depending on your altitude and mods yours may be different.
I want to get the K&N air filter eventually since I just do street riding, but I'm not sure if I'm going to have to re-jet. Doing a quick search doing a 3x3 mod with re-jet and a full exhaust are common modifications and an easy way to get some power.
hello what size did you use jet ?
New to the Drz community here. Which jet kit do you recommend after doing this mod?
What if u just do the 3x3 and remove the baffle is it same jetting as if you have a slip on
Good Job!
Nice video.
gracias mi pana es de gran ayuda
10:15 ..wait.. now the ecu is covering half the hole. Why does it need to be specificly 3x3 again? I think I would test it out before I cut a hole. Maybe just remove the snorkle?
Ha this man was like i have a nice bike, i have nice camera, i should use them together.. and he wasn't wrong, nice video!
What should i go with 155 or 160 main jet if i have a slip on exhaust?
This is great, but I still have no idea "what" the 3x3 mod is, nor "why" I'd want to do it?
Are those power wheelies or are you clutching it?
Surely you would just buy the FCR39 carb instead of going through all this hassle?
DRZ400 ASMR!
I would like to know what and why you exacly doing. It would be nice to have subtitles atleast with some explaination
It's a common mod for drz 400 that's why he didnt provide a description.
Stock drz don't breathe well because of too much airbox restriction. The 3x3 mod is piercing the airbox To increase air flow. In addition To that you need increase fuel intake so that is why he removes the carburator to modify jets
great work Cuban we dot to do this to our 22. hope your out chasing today and #livetoride
I have this motorcycle but no spare part in my country how I can get it??
does the fuel consuption changed?
