- Part 2
This is a detailed video of cleaning the carburetor of a 2015 Yamaha TTR50 including disassembly and explanation. Process covered applies to virtually all carburetors but the details will be different.
When diagnosing the bike after a no-start issue I went through 4 steps (in Part 1) to get the bike running right again. Hopefully the detail in the video gives you the confidence to work on the carburetor yourself! It doesn't take many tools but I do outline what you need to do the job.

Great detailed video. You have given me the confidence to give it a crack. The reason im going to try clean the carb is because the idling fluctuates from perfect to almost dying, and also if I tilt the bike too much to the left or right the idling dramatically drops. So hopefully after a clean it runs as good as yours.
You've got this! Take your time. Good luck!
thanks mate supper helpful, got the little man up and running! ended up being spark plug but this helped me do an overall service check.
Glad it was helpful and glad it was a simple fix to get you up and running!
Hey man there is one piece that you didn’t show to put back on I’m stuck on it I’m trying to fix this for my little brother answer soon please!..
Hey there- what piece are you asking about? Do you mean the choke?
Yes!! That’s it how do I put it on to the bike?
The choke plunger just slides back in and then is threaded in. Check at @4:52 to see how I removed it. This one had a stuck plunger that I got out with a little carb cleaner. Going back in it should just slide in the opposite as removal.
The ttr has complicated carb design for a little bike. I just ordered a tusk cold start jet kit. We’ll see how it goes. Thanks for the vid.
Definitely more going on than in the carb for my leaf blower. Hope the kit helps!
@@alexdombi-weridetwo Funny you said that... I got a free homlite (older usa made one) weedeater 5 years ago that had a bogging issue. I tried everything... Long story... but not sure why, I decided to check the spark arrester. It was clogged with carbon. I threw it in the garbage and it ran perfect after. You could also throw it in some gas and clean it if you want to re use it... Hope that helps.
When routing the throttle cables back from the carb to the throttle, do the cables cross over to the right hand side of the bike and pass through steel condute holder attached to the bike then up through the neck and over the handle bars?? Or back up through the lefthand side through the neck etc.. the first senario i suggested seems logical but the cables seem a little tight. Ive brought a second hand carb and throttle assembly which is a completely different carb to what was on the bike, duel cable. So unfamiliar with setup but its the same carb and cable as the one you have installed.
I wish I could send pictures to help with this! If you look at 5:57 in the video, you can see the cables are routed through the cable ring on the right side of the backbone and then up in front of the bars to the throttle. You do need to make sure there isn't extra tension between the cable ring and the tube- as much slack as possible there to prevent binding.
Hopefully that helps a little
@@alexdombi-weridetwo yeah ok thanks for that, i think where on the same page, pretty sure ive got it right. Just to me it looked like if i ran them down the left side instead of the right the cables would be more relaxed and on the right approach to the carb, but theres no cable ring on that side to support it. Algood thank you for the quick response🙂
Great video mate … any idea what the standard idle screw setting is ??
Please search for a service manual of your specific year to be sure, but I believe it is 1.5 turns out from seated.
I could get my ttr50 to start but I have to hold the gas, it won’t just idol. When I took the bowl off the needle was sitting in the bottom. How does that go in and stay in? I haven’t taken the float off of it.
Never mind. Your video helped me out a lot. Thank you!
I'm so glad to hear it! How did your float needle fall out? Or did you mean a jet?
3:05 how did you slide the carburetor off after taking clamp off ? Just by pulling it out ?
Yes, once the intake clamp is loose, the carb should slide out.
Hey ive been looking for a crab for my ttr50 2013 but only 2006-2011 show up idk if they can fit
I'm pretty sure 2012-2024 is the same carb. Check on the parts fiche for your year and see what the part numbers are and compare it to a 2011- their may be some small details changed.
@@alexdombi-weridetwo yeah man i couldt find any on there also i also noticed that the cab is leaking out gas from the bottom I tightened the little bolt so it wouldn’t and still does it
That can happen if the drain bolt is stripped out even a little bit. Is that the reason you are replacing the carb?
@@alexdombi-weridetwo well i replaced the spark plug battery and mostly everything u did in that vid and it still wont start so I noticed when i would turn the gas on it would leak also but the bike hasent started and im pretty sure it that carb
If it leaks when you turn the fuel on then the float valve needs to be replaced. It's what stops the fuel at the right level. If it doesn't, it'll flood the engine with fuel and it won't start. Look for an All Balls Carb rebuilt kit.
How did you end up getting the choke cable off
It was actually just stuck in the carb body- the plunger pulls right out. The cable is held in the plunger with a slot/insert. If yours is stuck and you're doing a full rebuild hit it with WD40 and it should slide right out. ;)
Where does that small black hose go at 22:45?
It runs up over the carb, along the topside of the air box and back towards the rear wheel. It's a vent line.
forgetting the exhaust is my fav. part. lol
😂🤣😂
Really my dad copied everything in this video and my old ttr still wouldn’t run
😓 sorry to hear that. There could be a few other things causing it not to run. Are you sure it's the carb as an issue? That's the most common issue.
