DRZ 400 PROBLEMS: IDLE ADJUSTMENT 

3:35. That’s not your air/ fuel mixture screw that’s your float bowl drain “plug” screw. Don’t try and adjust that. It’s for emptying the float bowl. Mixture screw is UNDERNEATH the float bowl and points down towards the ground and you have to either use a small “wheel ratchet” type screwdriver - or loosen the flexi hose clips and turn the carb to get to it.

Had the cutting out problem at high speeds (on highway or just when I open it right up) for over a year now... I'm no mechanic and nobody here seems to know what they are doing. I have my idle set high ( don't know what rpm) and I just bought the extendable air fuel mixture screw so I can adjust by hand. Will have to play around with it... Litteraly the only problem my bike has had since I bought it... Does also blip blip type of backfiring but nothing to bad. Really wish there were decent mechanics in cambodia 😳😳

Looks like that is the same problem my bike has. Came brand new with a massive idle problem. If you turn off the choke the bike instantly dies it idles so slow. A buddy tried to ride it and he had to ramp up the rpms so high to be able to keep the bike running. I'll try your fix and see if it helps. I'm just amazed a dealer would send it out the door like that. Just too far from a city to run back for a stupid problem like that.

Thanks from down under. New to bikes. Helped me out.

My bike is a stock 05 SM. All my friends were popping their bikes on 2nd gear at low rpm and my bike just was struggling. I raised up the idle a bit and magic. Lol thanks bro

Thanks, man. I got a brand new DRZ a few days ago and mine does the *same thing* when I blip the throttle. Couldn’t find an answer anywhere bc every forum is talking about old ass bikes. So they were talking about gunk in the carb. I also don’t know what 1,600rpm sounds like of the top of my head, so using your vid as a reference, I got it to stop!

So the white plastic flathead thing is the idle screw? My bike cuts out when I hit the throttle but only when it's cold, if I use the choke it eliminates the cut out altogether.

My drz started doing the same thing so I changed the spark plug and boy did it help. You should try that if you haven't changed it since you bought the bike.

Thanks great help on my 2005 DRZ 400SM, from Scotland UK, due to Euro emissions we no longer have this bike available from 2009 onwards,

My idle screw is not in the same spot as that and I have a fcr carb. I also installed an rpm gauge and its always at 1670ish, and I still have blips in my throttle. Like a small twist of throttle though and also it cut out on me the other day at a red light. Should I lower the rpm ??

My bike was doing the same thing. Turned out to be the tiny screw that sits on the needle in the diaphragm of the carb. Super easy to check, just take off the top of the carb and pull the diaphragm out and make sure everything is in place. My screw had popped out of place and was just floating around the top of the carb.

Good video bro what kind of program do you use to edit your video

i love the yellow such a sick color scheme. i just got a 2018 a couple months ago. appreciate the helpful vids!

My drz is also idling super low after a few mods and it's idling super low, almost dies at stop lights even after warming up. I'm gonna try and adjust this idle adjust.

Hey man, thanks for the video! My DRZ has been idling super high. I don’t even need to give it throttle in first gear and it goes 15mph. 🙄 and my throttle isn’t sticking. Can’t wait to try adjusting the throttle tomorrow!

I would be following the mechanics advise..... i.e. idle air screw needs to be set richer not your idle needs to go higher, its kind of like fixing something but not really fixing it... grinding off the diaphragm is from the pumper not the air vacuum diaphragm,,,, not sure how he got that mixed up.... if you look up Eddie Mod on thumpertalk there is info on the mod to get better acceleration off idle by activating the pump earlier/longer......

awesome, keep studying, enjoy the drz. I'm cleaning the carb, ugh, and lordy, if all I needed to do was tweak the idle I'll be kicking myself, but still, afterwards I'll be smiling and singing in my helmet, LOL>

Hey where you at in so cal? I cant find any other supermoto riders around me

hi ! how to know exactly the RPM ? there's no tachometer on that bike

Why's he grinding the accelerator pump nipple?

bro so happy i watched this.. I had a new chiming chain replaced on my DRZ and the shop didn't even test run my bike after.. i rev it at a stop and dies.. cant wait, going now to adjust

Please tell me where you got the black bar clamps for the fatty haha. Thank you for the vid. My bike has the exact same issue I’m about to go outside now and try it

My drz accelerate only 3000-4000 rpm and Max speed 80-90 klm/h and the half throttle to end is dead, why?

I’m gonna try this out I’ve been having the same issue. I’m new to carb bikes so this was very helpful

Same problem I had too, bro great video

Thanks man my 2018 drz 400 does the same thing and adjusting the idle has fixed it

I have drz 125 coolant elbow problems how to fix

Which tail bag do you have and how did you fit it?

So you re jetted with the 3x3 mod?

Another great video.....keep em coming bro!

Thanks that worked great for my bike as well

Get yourself a flex R&D mixture screw. If your bike bogs it’s rich if it hangs it’s lean

Had the same problem with my DRZ bro. I adjusted the idol and it was fine. It still hogs out sometimes but I just keep adjusting the idol and then it’s fine for the rest of the ride.

Where did you get those nice yellow plasitcs?

How do you know what your rpm’s are ?

Did that manual come with your bike? If not, where did you buy it?

How’d you know where your rpm was without a gauge ??

Just some Motovlog action of the DRZ in its natural habitat. PS. I finally got a few motovlogs out on my DRZ. Love that bike!!!

Great video! Keep em coming

Are you still running it at 1700

Still no trouble with that loud MRD?

Thanks bro I think this solved my problem too 👌👍👍👍

My drz is doing the same, dies when I rev.... I'm definitely gonna play with it... thx bro

Great Video! Get that education first, RU-vid will be here when you're done with school

Low or high it seems

Great video thank you

It's crazy buy that bike coming from a 2t 50cc??, I want to buy It but I'm afraid off being so dangerous for me xD Tall 1,82 Weight 74 Experience 2 years 50cc Sm

yo!! your're selling your bike!?

Ah I forgot, Suzuki still makes the carbureted bikes instead of the fuel injection.

Thought I might get help on this but I just got to watch someone poorly explain how they fixed theirs.

how tall are you??

1700 rpm sounds way too high to me 🤷‍♂️

Nice vid.

Put USD to drz

Jesus, please keep in the motovlog, don’t do technical videos.

That screw you were pointing to next to the idle speed knob, is the float bowl drain screw 😈...NOT the idle mixture screw. 😨 The mixture screw in under the carb, can be plugged up from factory, and is difficult to adjust. I could see you had no idea what your learned friend was talking about 😅 Young chubby people like you are responsible for influencing naive youtubers to learn shit. Look back on your vids in 20 years time and cringe!😂
