Cheers buddy. Very informative. I’m having issues with the exact carb on our KX125. Last week the throttle got stuck open. It wasn’t the cable or throttle handle but something in the carb. I’ve stripped the carb down twice now and cleaned it all. It ran when I put it all back together but after a few minutes just died again. I think there are a few issues with it and just trying to work through them.
I’ve had a play following watching your video. The last time it started it seemed to run out of fuel. After a few minutes it would then start again. So I’ve stripped it all down again and found some crud in one of the jets. It’s fresh fuel but I’ve ordered some inline fuel filters as that was great advise. The idle speed seemed ok when it did run and I’ve checked the jets and fuel and air routes. I’ll get the filter on first and then continue. Cheers buddy.
@@wutupclegg6618 yessir, what main jet do you run. My 2001 cr125 came jetted so bad it barely ran I have it in pieces but thinking of buying like 350-390 mains and a 40 a 45 and a 50… any suggestions to not waste money on jets? Also under the assumption it has a red needle from jd kit and I haven’t found a oem one yet or a 2171 that old riders said they used trying to get the bike close to stock and work from there
Sorry for the late reply. It didn't show on my message board. I run the stock jet. The bike is stock, so there's no need to change it. How is your bike running? It might ba another issue.
I haven't heard it called that in decades. Try looking searching "Needele Jet" instead of "Emulsion Tube." Needle jet is a lot more common name. eBay has them. Also, Google will have a list of suppliers.
Hello Keith. Good question. The rule of thumb is to adjust the needle every 3,000 ft. To be 100% sure on the jet size, I would call a motorcycle shop in that area and ask what they are using. All bikes are different, so I wouldn't want to suggest a size.
so nice video!. whats is the main jet size on a yamaha yz 125 i have the same carburetor in the video. do you know that.. i dont have the manual and whats the float height is?. soo good video:)
Thank you for the compliment. Sorry, I don't have that info, you are asking for. I would highly recommend getting a service book. It will tell you everything.
The jet that pull fuel for the carb. Does it get smaller inside? Can't seem to wondering if its clogged or just smaller the the opening up top. Also does it come off? Thanks
I apologize, I wish I really could give you those specs. I don't have those specs. some rebuild kits will come with those screws, and you can find them to be quite inexpensive. You will also need the springs and washers. You will need to search for idle adjustment screw and air/fuel mixture screw. Those are their proper names, just in case.
Did you take the slide off the cable? To get the slide off, there is a button at the tip of the cable. Push the cable into the slide then slide the cable to the side. You will notice a cut out where the button will slide out. Then, you should be able to pull the rubber boot off the cap and pull the cable out.
Hello David. Which seat and needle are you referring to? The float needle and seat? I already have the carb back in the bike, but I'll see what I can do. I believe the carb is a 36.
hello, I would like some advice, I have a newer tmx 38 on a honda cr 250 07, I have already changed almost all the parts on it, I use pj32.5(40) mj 410(420) needle 6gdy26-68(26-65) the engine runs great but I can't set the idle speed... I have to raise the slide and then the engine fires down the hill when the gas is taken off, where could the problem be? how do I set the idle speed so that I don't have to raise the slide
yes, exactly, everything is OK, but idling has problems, the motorcycle has no problem starting even without a choke, and it has a nice idling, but when I add gas, the idling drops and is terribly low and after a while the engine stops. it's annoying that I already have the freewheel screw and the nut turned at the same time, even so the freewheel is weak, but it's probably drawing gas under the slide because it's firing down the hill
@@jonny621 I don't have the jet size requirements, so I'm assuming you installed the proper size jets. If your engine has been bored out, you will need to install bigger jets. If a bike will not idle, but runs when giving it gas, it is most commonly due to leaking shaft seals. This is noticed by seeing if there is oil in the stator compartment and/or your bike is smoking really bad. If your bike idles, but doesn't run well, this is usually due to wrong jet sizes. Usually, it due to small jets. It can even be due to a leaking carburetor boot or a bad reeds valve. If it starts without the choke on, it might be due to the fuel level, in the float bowl, being too high. Sorry brother. Without it sitting in front of me and seeing what's going on, I can't be more exact on what's going on. Keep me posted on what you find out.
@@jonny621 if there is no change in idle when adjusting the air mixture and idle screw, then it is most likely leaking shaft seals. It's about that time to change them anyways. The good thing is, the seals and gaskets are cheap. The bad thing is, it's a lot of work. If you have old clutch plates, you might want to change those out at the same time. Same thing with rebuilding the water pump. Thos all need to come out, so you might as well change them.
Best tutorial for Mikuni that I have seen
bookmarked it
thanx!
Thank you! I appreciate the compliment.
Yeah!!!
.
This is a fantastic video. Just picked up a cr250 with the tmx and I really appreciate all the info you put in this video
Thank you for the complement. Hearing responses, like yours, is why I make these videos. Let me know if you have questions.
Fantastic video, very informative big man thanks

How does it run when started? When it dies, is it because it will not idle?

@TheMCMoosey how long will it run for?
Not long. Less than 15 seconds. Then give it 5 minutes and it would start again but do the same.
@TheMCMoosey that could be a couple issues. It could be the float needle isn't opening all the way.
What up cleg thanks for the video not too many on the ole TMX cheers bud
You are very welcome. I'm glad you liked it.

Great video..when going too higher altitude "10000" ft. Is it necessary too rejet or is needle adjustment enough?

Are you referring to the main jet? None of the jets change, in size, inside the jet. The needle changes diameter.
How do you drain it???? I can’t find the bolt
Hello.
You drain the bowl by loosening the large bolt on the bottom of the bowl.
@@wutupclegg6618 yes I just got it. Someone said it undoos the entire carb and thought that was weird. Thanks for quick response tho
@@ChickenDock Not a problem. It only takes the bowl off if you completely unscrew it.
Can u plz tellme the throttle screw and the air flow screw specs of the tmx 32 for 2s plz.
I got one tmx without the screws

Great video. What are the cast aluminum hose connections for?
Thank you for the complement. Those are vent lines.
How do you get the cable to separate from the cap, is there a c- clip, or is it just pressed in ?
Did you take the slide off the cable? To get the slide off, there is a button at the tip of the cable. Push the cable into the slide then slide the cable to the side. You will notice a cut out where the button will slide out. Then, you should be able to pull the rubber boot off the cap and pull the cable out.
My Carb is not sucking fuel. Everything is clean and none of the holes are clocked.
You got any suggestions?
Sounds like your float level is too low, or there is a crack in your carburetor boot, between the cylinder and the carb.
@@wutupclegg6618 none of that, it was overflowing at one point. i think the carburetor slider sits too high.
Are you sure it's not sucking gas?
@@wutupclegg6618 10 kicks with fuel on and it was dry so yeah im sure
Did you try starter fluid? It could be compression, leaking carburetor boot, or a bad crankshaft seal.
Can you show a video replacing need and seat and link below to order parts. Also what TMX is this 36 or 38
Hello David. Which seat and needle are you referring to? The float needle and seat? I already have the carb back in the bike, but I'll see what I can do. I believe the carb is a 36.
@wutupclegg6618 Sorry yes float needle and seat
I'll see what I can do. The carb is back in my bike.

No one had ever called the pilot jet a jd jet 😂😂 jd jetting is a company that makes jetting kits for dirt bikes
LOL.. I actually had to go back and see what you were referring to. I was actually saying "jiggidie jet." I was just having fun with it.
@@wutupclegg6618 ohhhh, my bad. Its definitely a good informative video
@@stephenblackstock1923 thank you. That's a nice bike you have in your picture.
