Great vid. I’ve been working past day on my son’s 2006 Husqvarna SM 125. Broken gas wire. What a mess! Previous owner had customized it for street stunts. With this vid I could finally identify the carb as 2002-2004 Honda CR125/250 MTX 38 4.0. And gas handle was from Yamaha. What a mess trying to find right parts with google pictures
I pulled my 2001 cr125 out of the junk pile and hope it works after 12+ years of being in the weather. I cleaned the carb today but needs all the plastics, tires, throttle, and brakes checked out. Hopefully this weekend I can make time to ride it and start ordering parts.
Awesome video got my non-running bike to run. Amazing. Thank you. My bike was a 2000 YZ 125, but they have the same carburetor as the CR so the video was great help.
I haven't personally done it, but if the yz has 38mm on it now I'm thinking it would swap. But possible clearance issues? Probably have to mess with the jetting as well. 👍
Yeah, that can be one of the hardest parts to do. The metal tab just needs very minor adjustment and it makes a big difference in the height. Unfortunately it's just trial and error.
Nice video ! Curious if these Mikuni TMX carbs came stock on these bikes or not ? Some blogs out there saying they did, and the Honda parts guys seem to have no idea, even when I give them the serial #... I guess I just want to make sure I'm getting the right rebuild for mine. It's the same year as your bike and appears to be the same carb, even though it doesn't specify with a model # ... Any help would be appreciated.
I actually have to do some work to that carb soon. There's a small hidden gasket on those carbs. Not sure when I'll get a chance to get to it, hopefully soon.
@@AdamzGarage my son bought a broke one. Rebuilt the engine. We have spark. We didn’t get fuel. I thought it was one of the hoses. Believe I have it right but still won’t start up. Maybe the Reed’s in wrong. I don’t know. Kinda lost. Watched your video. It helps but still stuck
@@wallymorgan2524 yeah basically as far as the hoses go, should just be your gas line, the line that comes off the bottom should just be an overflow line that just goes down by your shock, doesn't hook up to anything, then the other port by the pull knob should just be a vent line not hooked up to anything.I think your headed in the right direction with the Reed's good 🤞
We had the same problem with my son's, running rich more than likely. I would recommend trying to re- jet a size. I just ordered a couple different size jets for my son's CR. He just started riding it recently since I did the Carb rebuild and we're having the same problem, excessive smoke and oil dripping from exhaust . You could try to change your fuel mixture like you said and see what happens 40:1 isn't to bad. We run 32:1.
@@AdamzGarage I think the other issue for me is I'm running it more on the "trails" and not staying hard on the throttle. I did add more gasoline to the tank to lighten up the oil and messed with the idle screw.. seemed like it reduced the smoke and oil spewing out the exhaust. Where can I purchase a carb rebuild kit? The bike has a Mikuni carb, fmf pipe and I live in the high desert about 3,800 to 4,000 elevation.. if that matters. Ty
it should definitely help for sure. there's also a small gasket that they don't show on the exploded view on the honda site. This gasket is known to be the cause of a lot of the problems with these carbs. Ill see if I can find a link for you. its hard to find. I think there's a guy on ebay that sells them.
For sure that jet block gasket is a must. Don't know why it doesn't come with kit. Jd jetting has it. I also used Yamaha s7needle ,clip on the 2 notch. Woke that dude up,supper responsive
It actually ran really well. At first it didn't want to start, but it had been cold, so I used the choke. Started up took it down the trail and ran nice.
@@AdamzGarage hey my bike isn’t starting and I haven’t cleaned or out touched carb but ordered the rebuild kit has same carb as cr but it’s a yz125 apparently it’s used in the older yz but I have a 125 so if I rebuild would that help ?
@@JayWithTheAmg it definitely can't hurt either way. A rebuild at the very least will help it run better. If your bike won't start at all, make sure your getting spark and have compression. If you have that then it should be a fuel problem.

Glad it helped. Good detective work on your part. 👍
Brilliant thank you very much for taking the time to post this. I found it very useful rebuilding my sons 2002 cr125 carburettor

Hey so if I buy a used ‘00 cr125 for my 00 yz125 it would fit perfect even tho it looks a bit different?

@@AdamzGarage I just bought it like 5 min ago it’s the same carb I just have too lean it a little bit thx tho
@@AdamzGarage and for the yz the had the 36mm from 98-00
Man why does everything on my bike just have to be freakin broken to get off (Phillip heads)
I hear ya, nothings ever easy..lol.
I need my float to stay seated exactly at the height I want it at, but I can’t seem to get it set where it can stay on it’s own.
Yeah, that can be one of the hardest parts to do. The metal tab just needs very minor adjustment and it makes a big difference in the height. Unfortunately it's just trial and error.
If you run a 7s Emotion tube
Stock is 9s
And 6chy12-82 needle this will get ride of low end bog.
I have the tmx video, take a look at it.

Pilot jet/main jet number?
Change the gasket join man!
Its the only problem on the carb
Hey man, can you make a video or show us how to tune the carb. Specifically for the carb on cr125r
I actually have to do some work to that carb soon. There's a small hidden gasket on those carbs. Not sure when I'll get a chance to get to it, hopefully soon.
will the rebuild kit on a 2002 be different ? i’m looking at one on amazon and the gaskets look slightly different
Could you tell me where those hoses go on the carb asap
I'll run out to the garage tomorrow and take a look, been awhile since I worked on the cr

You should consider a lectron
Thanks for the tip. They look like a sweet carb.
pos
@@matthew7448 why a pos?? Everyone loves them
This works for the 2001 Honda CR250 carb as well. Same basic design
Hi there I just wanted to know what size pilot and main jet those carb bring from factory??
It usually depended on where the bike was being sold. Altitude has an effect on jetting. So depending where your riding can make difference.
I have a honda cr 125. and after an hour of driving my spark plug burns. what is the cause?
I would think to much fuel but idk
yea pretty sure its your mixture
Et le joint à l intérieur du puit d aiguille et du ralenti 🤔
i have a 94 cr125 with the stock carb,all it says on it is oem,i wonder if its the same setup,looks similar,this helps alot tho,thanks
I'm sure a 94 is very similar. Good luck with your project!
26mm?
Been awhile since I've worked on that bike but I beleive it's a 36
Great tutorial , Awesome !
I have an 01cr125 and it's spitting oil out of the exhaust. I'm running 32:1 I'm thinking going up to 40:1. You have an idea what the issue is? Ty

I had the same problem. Had to change the crank seal on the transmission side
mine idles very high, and shoots oil out the exhaust, would this fix it

Did you check the jet block gasket? They say those go bad very often.
Interesting, now I'm not sure if that came with rebuild kit.

Thanks,this help a bunc😊
Your welcome. Glad it helped!!
I have the same year and I’m wondering how did it run after you installed the carb with the rebuild
It actually ran really well. At first it didn't want to start, but it had been cold, so I used the choke. Started up took it down the trail and ran nice.
Adamz Garage thanks for the reply ! I think I’m going to try it out cause I just did a rebuild and it’s running too rich for me
