DRZ 400 PROBLEMS: IDLE ADJUSTMENT
Вставка

- Back at it with the vlogs
Summary:
The 3x3 airbox mod I did to my bike seemed to make the air to fuel slightly off naturally by forcing more air in. This caused my bike to cut out whenever I would blip the throttle in neutral. I thought the problem was my air/fuel screw (at bottom of the carb bowl) wasn't backed out enough, but it turned out to be just my idle being too low. If you guys have anymore further advice let me know.
FOLLOW MY INSTA: @socalmoto714
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.
@Lovetoeat the pilot jet is clogged
Your carb needs cleaned
@Lovetoeat no prob bro
Pretty much. You can access the jets by removing the seat tank and throttle cables, then spinning the carb so u can access the float cover screws on the bottom. Remove it and the jets are inside
Or just pay A reputable shop
Good call
No mate, that's your idle speed screw. He did the correct procedure.

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.
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
Same my bike won’t pop in second gear very well lol. I’ll try raising the idle a tad
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 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 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.
My drz is doing the exact same thing
Thanks from down under. New to bikes. Helped me out.
My drz accelerate only 3000-4000 rpm and Max speed 80-90 klm/h and the half throttle to end is dead, why?
Why's he grinding the accelerator pump nipple?
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 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.
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!
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.
Same exact issue, but new spark plug didnt help at all. Messing with idle screw is helping a bit, havnt found the right setting yet. Pilot Jets could be dirty too.
fronjm05 I had the same problem, turns out the little screw in the diaphragm of the carb had popped off and was just sitting on the diaphragm. Definitely should give that a look.
i love the yellow such a sick color scheme. i just got a 2018 a couple months ago. appreciate the helpful vids!
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
Here to break it to you m8, the chain has nothing to do with the idle
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!
DRZ400 eaither old or new have never changed :) but if the bike don't have a rev counter then finding out what 1600rpm is can be hard
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>
hi ! how to know exactly the RPM ? there's no tachometer on that bike
He has an aftermarket speedo. If you’re on the stock one, I guess just go by sound
Good video bro what kind of program do you use to edit your video
Taison Dal Col just iMovie. Nothing too fancy, other than the MacBook to run it lol
Cool thanks for the response I was just thinking of doing up some videos keep up the good work
Hey where you at in so cal? I cant find any other supermoto riders around me
I have drz 125 coolant elbow problems how to fix
Which tail bag do you have and how did you fit it?
Same problem I had too, bro great video
So you re jetted with the 3x3 mod?
I’m gonna try this out I’ve been having the same issue. I’m new to carb bikes so this was very helpful
How do you know what your rpm’s are ?
Thanks man my 2018 drz 400 does the same thing and adjusting the idle has fixed it
Thanks that worked great for my bike as well
Another great video.....keep em coming bro!
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
Where did you get those nice yellow plasitcs?
Stock
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......
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.
What is an "idol"?
My bad. Lol idle* I was high af watching this earlier.
Are you still running it at 1700
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!!!
Did that manual come with your bike? If not, where did you buy it?
MastercheefRyu bought it second hand on Craigslist. You can find some there, on eBay, even amazon.
How’d you know where your rpm was without a gauge ??
Michel Bakhos listen, you will know when its just about right
Great video! Keep em coming
Get yourself a flex R&D mixture screw. If your bike bogs it’s rich if it hangs it’s lean
Still no trouble with that loud MRD?
Tattoo Junk you get used to it lol. Sometimes my ears are ringing a little after a ride but it’s not too excessive most of the time. It sounds amazing
Low or high it seems
Great video thank you
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
bro did that fix it?
Great Video! Get that education first, UA-cam will be here when you're done with school
how tall are you??
I'm 5'7" and I flatfoot the drz with 1 foot and a slightly bent knee.. you're probably fine unless you're like 4'11" lmao
@@phill5829 I’m 5’9” with dirt tires stock I’m on toes unless I lean it down and slide off the seat about 1” towards the planted foot
yo!! your're selling your bike!?
Ah I forgot, Suzuki still makes the carbureted bikes instead of the fuel injection.
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

The bike will only do what you make it do and go as fast as you tell it to . With a sensible head and the correct license there's no reason that you can't go for a liter bike if you want . Just don't ride outwith your own abilities
Drz is very tall!
Thought I might get help on this but I just got to watch someone poorly explain how they fixed theirs.
Nice vid.
1700 rpm sounds way too high to me 🤷♂️
Josh Worrall I’ve kept it at 1300 to 1500 for the past 5 months and it’s just not enough. Maybe I could do more tweaking but 1600-1700 isn’t staggerjng
SoCal Moto see i know it says 1700 in the workshop manual but i run about 1300 ( flat cr 39 carb, rejetted, airbox mod, arrow exhaust) and mines quite even, 1700 for me sounds really high, but mines running really even, i do still need to take it to all be set off correctly though so 🤷♂️
@@josh20109 yeah 1300 is too low.. valves and cam chain hate low rpm on the drz. 1600-1900 is pretty standard
@@phill5829 yeah I'm running mine at 1900 now with the FCR39
@@josh20109 same.. if your idle ever starts to hang a little and comes down slow try dropping it to like 1800.. we probably have the same setup lol & 1900 is about the top of where mine idles without hanging
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!😂
norincobro capri lol 😂 people make mistakes man. No need on the weight comments keyboard warrior 😂😂
@@socalmoto714 nah he was born with all of the worlds knowledge.. except for chapter 382 - "basic human interaction."
What does his weight have to do with anything. Wow, you are the cringe-worthy one.
