- Some of the 2023 models are having problems with the carburetors

Dont wanna buy the kit? Try this The carbs are simply the OEM Honda XR200 carb (we typically used the 2001 model vear XR200 - but all the single carb XR200 carbs were similar). Honda and Keihin have discontinued them. You can source your own carb and then use our adapter www.ebay.com/itm/154200154288... to fit it up to the OEM manifold. You can either use the OEM Honda XR200 throttle and cable or source these on the aftermarket (Motion Pro should be able help). Avoid the eBay generic replacement XR200 carb. You only want the OEM Keihin Honda XR200 carb.

My buddy just got one, we are both short riders and so we both feel ur pain...
I purchased a 2023 for my son and had the same problems with it being lean from the factory. I went a little crazy and drilled out the welch plug and got to the D-shaped fuel screw. It was glued or something in also, so I very carefully drilled and easy-outed the fuel screw. I ordered a Shindy rebuild kit which came with a normal flat head fuel screw. The jetting is still lean so I need to get new jets, but I was at least able to get it adjusted to where it will start easily and idle. Thanks for the video, just wish I would have seen it about a month ago.
Great vid. Picked up mine yesterday, lean as hell and can't adjust A/F mixture. Mechanic at dealer even called kawasaki about it before I picked it up. I got it home and very carefully adjusted idle once it was all warmed up and got it to run without hanging revs while also idling without stalling but it's super lean and cold blooded. Will probably just end up swapping carb. I can tell it's going to be a fun bike though just riding around the yard.
Just got that carb kit delivered. 🤘
nice video,i just got mine for christmas and i have not had any issues with it,Hopefully it stays that way but eventually im willing to do some mods to it such as this,and like you said a big bore kit.Thanks man
Thanks for all the good information. I was just about to buy one for my son but now I'm thinking on going with a Honda instead.
After 7 years my stock carb begin to have problem, now just run on choke, died without choke. Bad your kit is out of stock everywhere! Thx for your video!
Good informative review and advice.
Really appreciate the video, well done.
I used one of the RMC cold start jet kits for my wifes Klx 140 and it took care of the known carb problems from the factory. Didnt ever have to mess with the D screw
Bought this bike for my son who was riding a 70cc Baja & a SSR 125 he’s been riding it for a couple years now 14 years old. I’m about 5”11 ish 215 definitely slower bike very soft suspension but can stiffen the damper you can feel it, very easy to go on harder trails.
I have a aftermarket carb from keihin and I went from doing 50 to 64
Hey what sprocket did you use? Also does the throttle cable come with the kit? And what tuni g did you have to do? Thanks! Hope to hear back! Just bought this exact bike for my daugjter and she is already seaking more power lol
Just installed the big bore kit on it from TBolt, came with the same carb you have in this video. Did you have to change the main jet out to make it run correctly? If so what size did you use?
Mine runs fine I’ve had it for 2 years now still runs amazing
Yeah older ones are great the 2023 have some issues
@@cherokeeronnie what issues bro I just got a 2023 klx rf
Carb problems. Valves being way to tight from
Factory. Plug not gapped right. Nothing major just small stuff
This kit has been out of stock everywhere for quite a long time. We’re you sitting on this and just got around to installing it? Clicked your link - sold out. As expected !
Wife has an 18 model she got new. It sat for a while after a serious injury. Cleaned carb petcock you name it.. hasn’t been right since. Even only ever used non ethanol fuel.
She wants to ride it again and have been chasing carb issues with it for too long. It’s gotta go.
If I can’t get this kit anywhere I’ll go the Smart Carb route
Hey brother, on the new carb, did you swap out any jets it came with or did you keep it the way it was?
Ronnie great vid, did you use the jet that came with the Mikuni Carb? Also how did the sprocket change the ride, I just bought one a 2024 KLX RL. Thanks
How is it holding up after many rides? Still seem like a decent carb?
I just put this carb on my sons 140rl and it definitely makes a world of difference. The only issue seems to be when we pull the choke out for a cold start the bike won’t start. Can you do a video on any adjustments you’ve made or just adjusting the carb in general.
I have a whole Facebook about this Bike if you wanna join. Sounds like it needs jetted I never have used the choke with this carb
@@cherokeeronnie ok awesome, I’ll go check it out.

@@cherokeeronnie awesome, thank you for the information.
Designed for adults and big youths, the KLX140 combines a rigid KX-based perimeter frame with long-travel suspension and large-diameter wheels (21” front and 18” rear), and a simple, yet reliable air-cooled 144 cm3 single-cylinder engine into a perfect-sized package. @danhambrick6331
I wanted the 140 1st cause of my height but went with the 230 rs hopefully I don't regret it. from videos I've seen there's more mods for the 140 the the 230. i
What jetting did you use?
How do you learn taking apart the bike? I’ve been gifted one and don’t know my way around it while wanting to make it run better
That’s the old ones you get a 2014 or newer it comes with a keihin carb and they run really good
And some power mods like a bore kit it’s got some umph to it it’ll get around
But for midsize bikes the Honda crf150r is probably the best
Mines a 2023
@@cherokeeronnie really damn
My brothers is lean but runs like a champ
Only problem I had the fly wheel bolts backed out and fucked the stator all up
But I had a parts bike so it was no big deal
But runs really good I put it through hell and it takes it
So 28mm carb big gun pipe aftermarket computer 170 big bore over sized head valves. Mine does 77 down hill ready to scatter
Where’d you get big wheel kit
can i use this carb for my klx150 2023
Great bike I just raced it in a harescamble
Yeah I love it I have a full build over on @fistfullofdirt
Also I wonder if the older carbs are more adjustable mine is a 2013 and I was able to tune it decently
Yeah I do believe so I know a lot of people with the new bikes are have weird carb problems
I put a vm26 on my stock 140 and I can’t seem to get full throttle, it just starts popping and dies out. I’ve tried jetting the main from 150 to 200 with no luck. It also has a horrible stall when revved from idle which I’ve tried 15 to 22.5 on the pilot. I was told be BBR that the vm26 is too big for a stock bike and I need the big bore kit to use the carb. How did you get yours to run so well?
Sounds like the carb needs a good jetting/tunning. And that can’t be true because I run mine on a stock bike and it does great. Go subscribe at @fistfullofdirt going to have a bunch of tunning videos over there soon on this bike
Finally got the new carb in. Fired up first time HOWEVER the bike is revving like a madman. Throttle cable springs right back, choke is not on. No matter how I try and adjust the idle it wont stop revving. Any ideas? The one thing that did happen on install was the rubber "hose" from the air box to the carb came out. I reinstalled it back in the airbox but have not sealed it back up. Could that be the issue?
Throttle cable hitting the tank
If your front wheel is wobbly at high speeds change your compression and rebound.
No it needed true that’s all
When you quickly rev the throttle does it bog? Mine does. No matter what setting the fuel screw is on and doesn’t matter what pilot is installed.
No mine never did bog
I’m leaning towards the Honda CRF125 big wheel. Equipped with hassle free fuel injection, electric AND kick start. It’s not that much more money either
It has drum breaks in the rear and it’s very under powered at least the klx140 you can tune it to get more power
I love Kawasaki's
link on that sprocket? or did i miss that?
ordering the kit now, my sons bike is having tons of carb issues
thanks for the vid
I think he changed the 13 tooth to a 12 tooth thats what I did
JT Sprockets JTF1501.12 12T Steel Front Sprocket a.co/d/7BhyRwQ
Yes sir that’s what I done
@@cherokeeronnie thanks man, this fits a 22 140r? Shows up as a nofit, thats probably why my searches weren't coming up with it. Cheers
I bought the kit and put the new carb on. The fuel selector valve completely blocks the choke. You can’t choke the carb. Am I missing something?
In fairness it did fire right up with no choke and it’s only 30 degrees. It starts WAY better than it ever did straight from the factory. It’s to snowy to try it out, but wondering if no choke is going to be a problem.
I can reach my choke I have long fingers though but honestly I haven’t even use the Choke it fires right up every time
@@cherokeeronnie
I’m glad I found your video. It’s amazing how much better it runs with that new carb. It’s sad the factory can’t just put one on from the get go.
Thanks for sharing the info!
Do you happen to know what jets came installed from factory for the 26.
190 main 22.2 pilot
What model carboreto?
What sprocket did you use? Higher or lower geared from stock
About a month after I got my kLX I put the 12t front sprocket on. It accelerates like a beast and the throttle is super snappy with the higher Gearing ratio. My only gripe is I loss a little bit of my top end, but I'm about to fix that and order a 49t rear sprocket to put my gearing ratio down to 4.08 which will give me my top end back without loosing all the acceleration gained (I'm at 4.17 currently gear ratio right now, which was a pretty good jump from the stock 3.57 ratio.)
Also if you're looking for sprockets that are very reliable and well made I recommend JT Sprockets, Renthal (If you wanna spend that much). And Bikemaster.
How’s the carb holding up? Just ordered one to maybe make this bike great.
Doing great I been ripping it every warm day we get
@@cherokeeronnie nice!!! Which jet sizes did you run, I’m worried the bigger carb might make the bike a little rich
I’m running a 180 main and 22 pilot jet my exhaust is gutted though, people usually run 170/175 main on a stock bike
@@cherokeeronnie okay nice, I’m thinking about getting an exhaust anyways and drilling holes in the air box so I think it should be fine.
@@cherokeeronnie I’m also at 3000 ft so hopefully I can figure it out.
I have the klx 140L and Im looking for some better and lower footpegs, also possible options for a taller seat if anyone knows of anything.
Cut them off and move them what I’m about to do Moto seat or add foam
Try Fastway pegs. Expensive but lower.
If you Floud your bike hold it wide open and start it.
What size sprocket? I have a 14 tooth I may try
12 tooth
What brand is the carb again ?
Vm26
Do you have to add the jets or does it already come installed?
They have some installed but you need to jet it for your bike because it comes with a 190 main and 22.5 pilot jet this kit I got comes with other jets
Yes I installed it. But some reason it’s leaking gas out of the pink drain tubes on the bottom
The float needs set
@@cherokeeronnieany idea what the spec is for the float?
How tall are you?
Not very tall my legs are short😂😂😂
@@cherokeeronnie 🤷 🤣
You need a TC 85. They’re way way faster
I have a Ktm 250 😂
next time get full size bike and buy a 175 dollar lowering link ends up 2 inches lower at seat plus shave inch off seat and restapple seat cover b ack on lower front fork clamps 1.5 inches
I have 2 full size bikes
ya & you wear high heels ? how did you lower the full size bikes ? @@cherokeeronnie
Weird.
