Suzuki DR-Z400 3x3 Mod (High Definition) 

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.

A simple video with good camera angles and no stupid bloody music like so many others do. Thankyou very enjoyable.

I don't even have a DRZ an I'm watching. Thanks

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.

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

This man knows how to work a set of vise grips!

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!

Nice vid! Clear visual instructions/walk threw. Well done! There needs to be more vids out there like this.

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.

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.

Yesterday I followed your steps in this video on my 2018 Suzuki DRZ400sm and yes it was worth it 100%

Brilliant video! I was fascinated till the very end! Precise, simple, clean... Thank you.

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.

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.

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

Thank you for doing this video! Planning to do it over the winter but as you said others videos were so/ so. Cheers!

This is a brilliantly done how-to! Thanks very much!

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.

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.

I think this is the best tutorial out there for this.

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.

Thanks for the video, definitely helped with my install.

Even though this is a bit old, it helped me greatly, good clear video, thanks.!!!

Your video helped tremendously thanks so much! 💪🏻💪🏻

Great video thanks. Very neat way of cutting the airbox too. I take it wheelies are way easier! Looking forward to doing mine!

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 bike is oddly pristine

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 video nice camera work and how to. Thank you

Excellent Video :) KB Honolulu, Hawaii but miss the 70s in San Diego with my Hodaka Super Rat ....

Those bottom bowl bolts can be a pain ... I like the technique you used I stripped one and used an easy out lol

Nicely filmed Mate! Precise and simple. Too bad I don't have one to play with...

Gracias por el vídeo. Muy bueno.

Cuban Rider, great video best I've seen!! Question what was the tape for towards the end or did I miss something.

Excellent!!!! Awesome job, thank you!

This worked so good. A carpet knife cut like it was butter

Helped a lot. Much apreciated.

Great vid. Thanks a million

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

Super awesome video. Thanks for sharing

Great video ! we work on DRZ's around 80% of them have the 3x3 mod.. More air more fuel more power.

My first mod was to remove that horrid strap across the seat.

im glad mine already had this done when i bought it, for a 20 year old bike its amazing!

very, very good video, thanks! Cuban Rider

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!

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.

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

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

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!

Finally good res video of this

Fantastic video.

Never fails! Every new bike needs mods?

Did you upgrade the exhaust too with this mod or just 3x3 and jet kit?

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

would this be worth doing to my CCM404DS which uses the DRZ engine albeit, high lift cam, higher compression head and keihin FCR carb? already rated 40bhp... would I get any increase?

if you dont mind what jet kit did you purchase looking to do this same mod to mine as well

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?

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?

What should i go with 155 or 160 main jet if i have a slip on exhaust?

how long did it take to force the carb back in? 2-3 weeks?

great video!

is that a new bike? because it looks mint

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.

Good video my mate but what were you drilling at the end of carb mod..? Did you just wind it out as instructions say ?

Do you know maybe an impact on fuel consumption? Is it smth like 20% increase?

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…

What if u just do the 3x3 and remove the baffle is it same jetting as if you have a slip on

To compensate the extra air intake you should get a less restrictive exhaust

Très intéressant, merci 👏🏻👏🏻👍🏻

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?

Is there substantial benefit to 3x3 mod with FCR39?

So im just getting into motorcycles and I plan on getting the drz so what did he just do?

so question why not just put an open airflow filter instead of putting a hole in the air box of th bike?

Looks like you did everything but add a longer air/fuel adjusting screw 👍 nice

This is great, but I still have no idea "what" the 3x3 mod is, nor "why" I'd want to do it?

What happens if you forget to put the little spring in the slide?

Reminded me of one of tbose space movies wigh all the silent scenes... Do like the grey colour sceme on the DRZ.

Surely you would just buy the FCR39 carb instead of going through all this hassle?

New to the Drz community here. Which jet kit do you recommend after doing this mod?

Rejetting carbs and expanding air box,right?

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 ?

hi and thanks for top quality video. is this the FCR 39 CARB or the CV carb? thanks

I would like to know what and why you exacly doing. It would be nice to have subtitles atleast with some explaination

Can anywone help me .. why my drz400 it dos't have power.. is like no power just maximum speed 45 mph an it dose 't phul like it should. I clean the carb ...change spark plug...

I have this motorcycle but no spare part in my country how I can get it??

Good Job!

i dont understand .. what was that for ? can someone explain more ?

hello what size did you use jet ?

Excellent!

carburetor year 2018 whats that ??

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!

does the fuel consuption changed?

Hey just bought my first bike and its a drz400sm, it has a full yoshi exhaust on it already but it hasnt been rejetted, so i'm tossing up doing the 3x3 with the rejet. Would bike mechanics be able to do this? or is this generally done by bike owners? Not to sure how i would go with pulling apart the bike and then reassembling. Cheers nice video btw!

Hi, please tell me what jetting u put in there. 145 main and 22.5 pilot?? I have a drz with a leovince x3 exhaust and im popping in deccel like i m a popcorn machine and can t find they re jetting spec. Plss tx

You need to get a nice hand impact for the float bowl screws

Nice video.

great work Cuban we dot to do this to our 22. hope your out chasing today and #livetoride
