- Rebuilding a Carburetor on a Yamaha TTR 125 Dirt Bike. www.CharlieKing.... This video teaches you how to rebuild a carburetor on a Yamaha TTR 125 Dirt Bike Motorcycle.
A DIY guy but I've never worked on a motor cycle. We bought a TTR 125 for my son and it started dumping fuel and wasn't idling correctly. After trying to clean the carburetor or carb without any change to the performance, I decided that it's time to rebuild the carburetor. If your bike is backfires or is backfiring, dumping fuel, or puking fuel, not idling, won't start, will not start, is constantly flooded or is flooding, consider rebuilding the carburetor. It will improved fuel economy (improve gas mileage), run better, higher performance, go faster, won't stall anymore, and be more enjoyable to ride!
This is a job any DIY'r can do, so go out and try it!

I never rebuilt a carburetor before but your video was awesome and helped me learn how to do this for our TTR125 Yamaha dirt bike. Thank you!
Your welcome!
on 15:14, the picture of the smallest jets, witch hole does the bigger holed jet hold
That's what I was wondering... were you able to find out?
Great question. Unfortunately, my memory of this from a couple of years ago is incomplete. Best of luck finding out!
Just a tip..get a weld tip cleaner and use the smallest feeler to poke and clear out the smaller orifices.
Great how to video! I've never tried to rebuild a carburetor - and I don't own anything with a carburetor anymore! I like the photo idea, and I'm thinking: take a video when taking it apart, then play it backwards to remember how to put it back together!
Thanks as always Brighton!
thankyou so much for creating this diy, I have been looking for a video about carb rebuild vid about my ttr125 2003, similar, helped me find where jets go
Thx Ethan!
Is this similar to the ttr230?
I'm afraid I don't know.
Best video on TH-cam by far!!
J Webster, thanks!
Hey honoring some one can answer my question on the pressure tube that is like a t the tube that goes to the right dose it connect to anything
Hey Charlie, this is an awesome video. We're about the same age and skill level. Your video helped me a lot. Thank you and keep making great videos.
Thanks for reaching out! Always trying to learn new things, stumbling my way into competency ;-)
Thanks a lot for making this. I appreciate the time you took as the video helped me a lot.
You're welcome!
What was the hose you pointed at 1:24 and what is its purpose. My ttr doesn't have one and I think it could be causing the problem I have
Sorry I didn't reply to this in a timely manner. I hope you found an answer to your question!
I rebuilt mine and it wont start and leaks gas how do i fix it
The tube you mentioned that is just pressure sensitive is it supposed to be connected to anything else on both sides ?
+Kevin Perez Are you referring to the black hose on the top? I did not track it in either direction. I *think* (and may be wrong) that it it's a pressure overflow hose.
Great video I'm rebuilding mine today
Thanks Enrique!
I have a question. I rebuilt my carb. the issue I'm having is I can figure out what spot I should set my idle and my air fuel mix screw.
Rafael, great question. The only way I know if to run the bike sand adjust it while it's idling. Listen to the idle speed so it neither sounds like the engine is lugging or running too hard. Hope this helps!
For future reference, before removing the idle mix screw, bottom it out and take note of how many turns it took to bottom out. Then remove it. When you go back to reassembling it, bottom it out and then back it off however many turns it took you to bottom it out before.
This looks similar to a Honda XT125 I rebuilt. I have a TW200 now, (rebuilding soon!) which I'm noticing is very similar to your TTR. I recall that there is a screw that has to be turned a certain number of times according to the manual. Where is that screw on your carb? Great video, thanks for the steady camera work!
I Wish I knew the amount you should turn the crewe you mention. Unfortunately that's higher than my skill set!
At 10:39 there should also be a washer and o ring in there. It can help if you look at a part diagram online. Also I like to take my carborators to get cleaned In an ultrasonic cleaner.
Levi, solid feedback, thanks! I'm unfamiliar with an "ultrasonic cleaner", maybe my results would have been better if I had ;-)
well you taught me how to take it apart then decide to end the video..... really helped.... meanwhile my carb is in a million pieces with ni direction of how to put it back together
Hey Adam, he does say to take pics of everything so you can put it back together. If you need help hit me up. I can hopefully assist you in getting it back together.
@@dunchadoit5421how does one replace the needle valve in the carb? I’ve oiled it but the o-ring doesn’t fit in there
Hi i have same bike but my chok wire it won't comoff n i clean my carb but now my bike dont stay on or running.
This bike was finicky for sure.
what you called the throttle body is actually the throttle slide. a throttle body is something used mainly in cars, similar to a carb, but slightly different. it was used after carbs but before electronic fuel injection
after that at 9:10 that's the main jet not main throttle body
yes it is normal that the float pin comes out easy. it's normally held in by the edges of the bowl
19:00 once more, throttle slide
Random_rapper20, thanks for that! I'm afraid I'm the DIY guy with limited knowledge/tools doing the best I can ;-) Always grateful for the input. I appreciate it.
where exactly does the other black hose go to? our doesn't have that hose.
Argh, that sounds frustrating. Sorry friend, maybe another viewer can help you out. I'm afraid I wouldn't even make a GOOD guess at this ;-)
Great video man keep up the work!
Thanks Areeb!
How much is a new carburetor?
For a TTR-125LE, OEM I’ve found to be $450
450
I'm noticing there wasn't a needle in the seat for the float. Had you already removed it before hand?
Great question, unfortunately this was several years ago, and I cannot remember. Sorry I couldn't be of more help!
@@CharlieKingCoaching those ttr carbs are the most stubborn I've ever worked on. If the floats aren't set perfect they won't run right no matter what you do. Poor design.
Great Video Bud. I restored 2 TTR’s a 90 and a 125. I clean the carbs out at least twice a year.
I will let the jets sit in carb cleaner for about 10 minutes after spraying them then I take a guitar string and put it through the jets then use an air compressor. The tiniest piece of debris will clog the jets and sometimes a pain in the ass to get the smallest piece out.
They are both 2007 stock and never had to put new jets in. Just replace the gasket. Also have to Honda CRF 50/ 70 and 110 and those Honda’s will start up forever with very low maintenance.
Such great feedback Philly! It really is just the SMALLEST fleck can mess with your carbs. Air compressor would probably made a big difference. Thx!
where can i find a good cheap rebild carb kit for an 125 ttr 05
Great question, @colin! I hope another viewer can support you!
Great job! I thought I was the only one left that said "schumtz!"
Schmutz is a powerful technical term!
Great video
Thanks!
It's a ttr standard I have the same one
i think the people working on my working on my Carburetor put in backwards. Im now trying to figure out how to take it out and flip it around.
Bummer! So sorry to hear this, VoLTiC! I "SHOULD" be pretty straightforward and not easily confused. I'd suggest taking ti back to them to make it right. If you paid for the fix, They should make it right for you.
Charlie King no just a friend i know who usually works on trucks not dirt bikes im sure me and him can go over it together and try to fix it.
Cool, congrats on making it workable for you both! I'm sure he wanted to do right for you, and would welcome the feedback.
Get a JIS Phillips.
Learning something new everyday... lol
Love the video.. ok need more video
just saying, carb cleaner destroys gloves. it's also extremely flammable
Scary stuff, I *think* it's a carcinogen as well (linked to increased risk of cancer). Happy to wear thick gloves using that stuff ;-)
It also destroys rubber in the carb e.g. the gaskets and that sort of stuff. Just clean it in the fuel it runs on. A eye dropper works well to push fuel through it to clean it
my hose broke off after I put it back on the switch so now my leg is covered with gas :(
actually in the same spot yours did
Oh no! Bummer!
I think I got a replacement at my local hardware store (can't remember the diameter tho....)
Thanks!
You're welcome Mich5ael!
