Cant wait to get my dirt bike i love yall thanks for helping me
Getting familiar with carbs, and learning how to clean them is one of the most important things you could learn on a bike. It really helps with tuning and troubleshooting. Sometimes you could get a bike cheap that won't start, and it could be as simple as cleaning the carb.
We agree!
@@TheMxFactory My son and I went to Hardrock in Ocala for New Years Eve. My son went out, and the bike started running like crap after the first lap. It would start and run, but would not want to rev. The minute you hit the throttle, it would want to die, as if it were starving for gas. I removed the carb, removed the main jet, and blew through it. This mucous rubber jelly came out, right onto my finger. Blew some carb cleaner through the jet, and the rest of the carb, and replaced. Started and ran like a champ. Big lesson for my son. It helped him realize the importance of understanding a carb, and knowing the general function of your bike, even if you are not a "mechanic." If I was not able to do what I did, the consequences would have been significant. 1) The day and riding fees would have probably been wasted. 2) I would have had to take it to a shop. 3) Spend who knows how much to get it fixed. 4) Shops often keep you bike for a week, even for the simplest things. 5) Dropping it off at the shop, and then picking it up from the shop.
That's why I love these bike build videos, where us regular folks could add to our knowledge and understanding of our bikes.
I am no mechanic, but there is something else that I've learned that I wanted to share. When I needed a bike to basically ride along with my little guy, I tried keeping the cost down and found a pretty good 2002 XR250R. Older bikes often come with some issues that pop up now and then. One issue I ran into was a leaking carb from a sticking float valve ... just peeing from the bottom. I went round and around taking the carb apart and cleaning, then rebuilding, and the issue would be resolved temporarily, but would resurface quickly. What eventually took care of the issue was polishing the float valve seat. After my experience, I would not clean a carb, or especially rebuild a carb without taking this extra measure. Here is a video that addresses the topic. czcams.com/video/zlez_hdoWYk/video.html
Vice grip plier trick saved my life! Thank you
Excellent video, the one thing that's super important that I feel you didn't touch on, was float height. Other that that really informative
first time cleaning my carb what should I know about the float height?
What about the float height?
it only needs to be adjusted if you suspect the carb is either flooding or is starved to get fuel into the bowl (float valve closes too early due to low float setup)
Where can I find out the float height for my carb for 125ke Kawasaki 1978
Just saying.... this is one of the vids that will get a million + views cause of the title and content... like for real, YZ125 are sooooo awesome!!! I'm a 2 stroke freak and my last 2 stroke dirt bike was a 2010 YZ125... thanks for this awesome vid. Merry Christmas to the YAMAHA owners :D lol
Thank you....very good easy to understand!
Great Video. This video needs a disclaimer regarding the dangers of Carburetor Cleaner & cancer.
Nice. No float height check?
Great video, about to take apart my carb and clean it and put it back together
Is there any tips or ways I can fine tune it in the process???
Great video thank you
Great video
Which stuff do you use to clean the things?
What year is that carb from mate. I had what I suspected to be a carb from a 2001 yz125, I ordered the relevant rebuild kit however the main jet is wrong. It’s a lot smaller. My main jet in my carb is the same size as the one in your video. Thanks in advance if you can help 🙏 ❤
Is it normal for the slide need to have some play even when tightened?
One tip I wanted to share is using JIS screwdrivers for Japanese bikes, especially when working with soft bolt heads like on a carb. JIS is something I didn't know about until recently. You are much more likely to strip the head by using regular phillips screwdrivers. It's a very subtle difference, but could make the difference between stripping or not. Just look for the little dimple for when you should use JIS. czcams.com/video/gEwVUZr5xxQ/video.html
Yup, good tip. I wished someone would have said that 20 years ago. American Philips don't cut it.
@@warrenlange6106 Phillips kinda cuts it if things aren't tight, but the minute you have to apply any kind of real pressure, you're like, what the heck. I would look at the Keihin carb on the side of the carb as confirmation that I wasn't dealing with a cheap Chinese knockoff. I used to be perplexed, until I found out about JIS.
Love ypur vids
Thanks Ryan!
I noticed when u put the needle back in under the float it wasn't hooked to the float is it supposed to be hooked around the float or just sit under it
Love your vids
Thanks Cara! We love your comments :)
@@TheMxFactory 💙
There’s micro particles that can plug the jets part way but you can’t see and they look clear I suggest using a bristle from a wire brush and running it through any of the jets
Is the jet holder plastic necessary I just opened mine and noticed I’m missing it I’m having trouble with the bike saying running and idling so just wanna make sure nothing could be contributing to the problem
My carburetor is leaking a lot when i start it(overfloat) but then it suddenly stops and only a pair of gas are still coming....
What is wrong with it?(keihin pwk 38)
My bike won’t even kick over with a clean carb. I have spark and 160lbs of cylinder pressure. I may have messed around with the carbs air screw and fuel screw a bit so now I have no idea what the settings should be at to kick over. How much would it cost to have a shop get the carb sorted for me?
i cant find the idle adjustment on my minuki 36ss carb??? please help
wher can i get holder thing
to clean the carb u can use normal fuel and toothbrush
Скажите пожалуйста какой карбюратор стоит на yamaha yz125 36 или 38 ?
I have a 78 125ke Kawasaki need to know witch model mukuni carb I have can anyone help me out
gloves?
Tech tip for carb screws... they’re not Philips on Japanese bikes. They’re the recently killed JIS (Japanese Industrial Standard). Buy some JIS drivers quick before they stop making them.

Is there a gasket for the throttle cable? Also is the throttle cable necessary to remove to get the carb out of the bike?
No
Carb cleaner will eat gaskets away. You're supposed to remove them before using carb cleaner on surfaces .
What are the gaskets? N how do u remove them?
Get a some dust-off aerosol spray for computers, if you don't have a air compressor set-up .
Is this the same with a 2021 yz125x carburetor? Or have they changed a lot since that year bike you’re working on?
Should be the same, just look up Kein carb
@@ryancorra3995 you mean keihin carb?
@@BigElly12 no
How take out bike
How do you get the throttle cable the lid?
Easy way to work on 2stroke carburetor is to disconnect the throttle cable from the throttle tube. By disconnect cable from throttle tube and housing, will free up the cable making giving penalty of cables slack to disassembly a eas. When reassembling carburetor us a pick at the cable end to lock the cable in the proper position / tension once the slide is connected pull cable tight,
What about the air flow screw??
Don't mess with air screw it will make ur bike run like crap I know
👍👍👍
One thing NOT Done is the (stop flot gasket). Which is a mean couse of failing issue of the TMX carburetor Air & gas flow .
You know about the airflow screw? On the yz 125
@@jonathanusery7269 what is it, you need to know about the air screw and what year, carburetor , and what have you done?
Awesome videos!! Really enjoy your thorough explanations!! Just wear gloves next time!! Those chemicals are harsh on your skin and absorbs into your body!! Bad stuff!!
i cant get the cable off the needle thing help, please 😂 this is the only video ive seen with the same carb as me
Open your throttle tube assembley take the small wheel out un hook the cable from the throttle tube thos will give u enough slack to unhook the needle at the other end
hello dirty motorbike. I really like your video. unlike with other channels that talk a lot by showing their faces and it makes me bored haha
Is it too late to win the bike?!
i dont think so i hope you win 😩
Nah I don't think so
I think 4 years is a little late 😂

You don’t rinse in water after clean?
Because water can cause rust or mix with the gas. If you want to bath it down as an extra precaution id suggest getting a small bottle of gas, sometimes I use an old dish detergent bottle obviously rinsed out really well and ill use gas to bath and rinse the carb. That works well. Also you could just buy an ultrasonic cleaner and solution at harbor freight for cheap.
i'm not an mx guy but i love your vids, i'm pretty sure that carb cleaner is bad for your skin so try to wear gloves man(even though i don't usually wear em either lol)
PRO TIP USE GLOVES
Really does it matter
Gammelt opslag og jo der er god grund til at bruge handsker.
"Party time with the carb cleaner" more like cancer time for your skin.
