- This was a video i put together to show how to rebuild the carb / carburetor on the Yamaha TTR90 dirt bike. This is a 2006 model, but would be the same as many other years (2000,2001,2002,2003,2004,2005,2007)
At the end i shot my dogs chasing me around (french bulldog and rottweiler mix) - Навчання та стиль
Great videos and attention to details other youtube instructors leave out. Thanks for fast forwarding through the slow parts. Also, you keep it short and simple without a bunch of yaking. Keep up the good work. You would be a great teacher.
Thanks for the feedback! I appreciate it, I got sick of sitting through 20 minute videos for 8 minutes of content! Good pickup on the teacher aspect, I've been told that in the past, so maybe one day! Thanks again for watching
Thank you so much for this video I have never worked on a carberator before but your detailed explanation and great camera angles where top notch. After my first rebuild I had too high of an idle but after watching and rebuilding again I noticed the problem and I was only able to spot it from your great camera angle! I started the day with a bike that would not start and ended with a perfectly running machine! Thanks a ton!!
awesome! thanks for watching, and glad i could help!
Thanks much man. I have an 02 that is kick only and I’m waiting on parts so I went ahead and disassembled, cleaned, and reassembled the carb. Cheers!
You just helped me out quite a bit. I've never done a carb rebuild, but I'm getting one of these for my kids. I'll be using this guide for sure! thanks.
Heck yeah!! I was hoping it would encourage someone else to do it on their own.. It was intimidating at first, but step by step - its fairly easy.
Thank you. Grandson's 2005 TT r90 was hard starting, then wouldn't start at all. Pilot jet was mangled and clogged. Rebuild the whole thing while I was there. Yamaha manual had minimal information so thank you for the details like, where the short and long springs go and how to get the needle seat out.
glad it was helpful and thanks for watching!
Excellent tutorial! I have my daughter's TTR90E sitting in storage and I know carb is all gummed up so this will be most helpful.
I just bought a 04 also been sitting for at least a year , gas turned to varnish also. just went ahead and put it in the local yamaha shop .Hopefully the repair bill will not be too much.Keeping my fingers crossed .Im putting a 9 yr old on it so I wanted to get it done right also have them go threw it and make sure everything is tip top , for safety sake . Really enjoy all of your videos keep up the good work.
richard bolt - thanks! appreciate the feedback. Sometimes its easier to let the experts run through it.. I have taken stuff apart, put it back together and had it run worse than before! Good luck with the bike, I'm sure the kid will love it!!
Man I have had my carb off about 5 times now and still had a top end bog or better yet, a sputter, that I couldn't sort out. The main jet was clean and the float height was reset to stock. Finally after seeing you punch out that nozzle and sleeve I finally discovered my problem. Everything else was spotless but these other two parts(that I didn't know existed) were completely clogged. I cleaned them up and what do ya know I can finally rev 'er out. Symptoms before the fix were that it ran fine other than wide-open throttle where it would sound similar to a two-stroke. The bike would also run fine without the airbox attached to the carb(Not recommended). If you are having the same problems that I was, then watch this video closely and you will see what you missed. Thanks Matt Dobson. I was about ready to give up on a cure for the bog. You the man!
Awesome! Glad I could help, and it keeps me motivated to keep making videos!! Thanks for watching
6yrs later seeing you pinch out that needle jet saved me. I watched 4 other vids that skipped it. TY
Thanks, your video helped me rebuild carburetor!
Tony / Texas
Glad i could help! thanks for watching
Great video! Thanks for sharing. Going to tackle this job 2moro on my sons ttr to stay away from the dealership
Devin Jenkins awesome, glad I could help.. thanks for watching!!!!
Great video. Thanks for this. I rebuilt my son's ttr90 carb.
I appreciate that, thanks for watching!
If you still read comments on this video the only thing I can complain about is not showing how to adjust the idol air screw especially with its terrible location (actually why I was here but did get other good info) other than that great video
J Teal appreciate that! Sorry about the idle screw, good point!
Good video buddy
Where does that top black hose connect on the bike? I took it completely off and don't see where it connects back on
Hello matt nice video man...question when you put the throttle niddle back do you set it all the way down ?like the air needle 1 3/4 back ? Do both needles have to be on the same position? Its because my motorcycle was running fine untill i rebuilt the carb and put all the parts back now wont start pls help! How do i put both needles back to factory so it will run again
i got the same bike ,whats type of carb i should get ?
selling my ttr Sunday, bogs out mid to high rpm , have cleaned the carb before but I don’t know what else it could be? Will try again tomorrow , needs sorting or buyer won’t buy! Great vid
sounds like one of the needles is clogged.. did you change those out or just clean?
Would this apply to a 2020 TTR 110
Thanks Matt, I took my carb out and was wondering where does the black hose that you disconnected before the electric choke wires? I know it connects to the carb but where should I connect the other end? Thank you
Scott Killian if I remember correctly that hose connects to the fuel filter? Sorry, I sold the bike so I can’t reference right now.. I’ll try to look up a manual
on my ttr90 I have to run it all the time with the chock on. does it need a rebuilt carb?
either the jets or passages are clogged.. You may be able to clean it all out, but you may have to rebuild.
If you leave your bike sitting with fuel in the carburetor for any
length of time, the fuel evaporates and leaves a residue which hardens
and sets like glue. The airways have been blocked in the body of the carb and
because they are so narrow the pilot jet is always the first thing to
block . Try high pressure air through all of the jets and carb body .
If this doesn't work try acetone and soak the carb to soften the residue
and then hit it with the air again . One problem with the acetone though
, it will wreck all of the rubber gaskets your carb may have , so
remove them first. Best bet is to always use a fuel stabilizer if the bike is going to sit.
Do you have a video on front wheel alignment? or know of a video? for the same bike, TTR90E
sorry, sold the bike last summer! i haven't seen any videos like that
I followed the giude to rebuild carb but when i put it back together the trottle sticks open. It doesn't spring back to idle when you give it gas.
I tried taking the throttle back out of the carb and the throttle will NOT come out of the carb???? Any thoughts?
+Evan Macaluso - sounds like the throttle was inserted correctly? I'm not exactly sure.. sorry i cant help more.. If you send a picture or video I may be able to help a little more
Great video but does anyone know where I can get a new carburetor for a ttr90 I bought one of Amazon and it came without a place to scrow the yellow and black wire and without an adle scrow i am looking for a carburetor thats the same as the one that comes with the bike
You can buy OEM replacement carbs for ~$300 from yamahapartshouse www.yamahapartshouse.com/oemparts/a/yam/50045670f8700209bc793092/carburetor#
Check eBay.. I’ve seen used ones on there..
I have the,same exact Carb but mine doesn't have,the electrically connections on the Carb bought the,Carb bran new are,those needed?
That is the carburetor heater.
Why does my ttr90 carb have no pilot air screw? It's OEM carb it looks like where it should be there is a brass cap looking thing with no option to put a flat head or screw driver do I have to remove it or what?
highter lower mine is the same way...?
Hey Bud. Question. What grove do u place the round washer on the needle. Does it matter which grove. Thanks
Silk Boxing anyone ever figure this out? I am in the middle of rebuilding And cannot figure it out.
@@ryanthompson916 Mine ran great, until the pilot jet clogged. My needle was set in the middle groove.
Thanks for the video. Where did you get that set of brushes? Also- my pilot jet has a hole at the top where you put the flat head- the hole does not seem to go all the way through- no matter what I try to clear it with- the bike runs after putting it back together, so it must not be clogged- but I just want to verify that that is correct if you can remember that jet. Thanks, Tom
I got the brushes off eBay "Carburetor brushes" if I remember correctly the brush should go all the way through, but as the saying goes "if it ain't broke , don't fix it" thanks for watching!
My old pilot did not have a hole. I got a new one and it does. So, yours is probably clogged like mine was.
Could not seat the nozzle back in, buggered it up pretty good now main jet won't sit flush
I just brought a 2004 ttr 90 for next to nothing it has been sitting foe years I drained all the gas that turned to varnish. Would you suggest just rebuilding the carb?
I did the same thing, and hoped for the best. I had on/off issues.. Once I rebuilt the carb it ran great.. So its up to you.. The rebuild kit is $35-$40, so it's a little bit of money. You can also try just cleaning the carb.. Spray a bunch of Carb cleaner throughout, and that may do the job...
Yeah for the money I think I'll try just taking it apart and cleaning it real good. Thank for tje advise
Matt, Can you post a link to the rebuild kit you used? The AllBallz kit I got did not have nearly the parts this one did. Thanks for the great video! Also, what are the wires for on the carb?
Jamie Loy i used Moose - CARB REPAIR KITS [1003-0329] UA-cam doesn’t like links! The wires are for the electric start! Thanks for watching!!
@@mattdobson123 thanks...after posting this I read that they power a fuel heater as part of the electric start process, as you stated. Thanks again!
This may be a stupid question but does anyone know where that small top tube goes/comes from. Not the fuel line the other small rubber hose that connect to the brass inlet.
Roy Murphy - its an air vent hose.. I can't remember off the top of my head where it goes to, but i'll take a look this weekend and hopefully get an answer.
hi I have a ttr 90 and it was leaking gas so I cleaned the jets and that wasn't the problem should I rebuild the carbs?
It could be a number of things.. gasket, float bowl issues, etc. It maybe best to rebuild
Sounds like the needle attached to the float is not seating. Or, is missing. Or, is misaligned.
My carb only has one float on one side is that normal or did it break off
My 2005 has one float with two sides that take up the whole bowl.
Just a question where is the Idle screw on this bike could u tell me that cause I've been trying to find it
+Mags Gaming - for this bike it is on the backside of the carb. you have to reach behind the carb. and feel for the knurled edge bolt.. the head is a little smaller than a dime.
@@mattdobson123 It appears to just hold the slide up a tad. Unscrew to lower slide, screw in to raise the slide.
Hey Matt! I know you sold the bike already but do you remember if the fuel line was 1/4? I can see you had a inline fuel filter and I was wondering whether a 1/4 inch one would fit properly. Thanks!
I'm nearly positive it was 1/4"! let me know if you get it working!
@@mattdobson123 Went just perfectly! 1/4 inline fuel filter worked great, also rebuilt and cleaned the carb. These bikes need a fuel filter right from factory because of the small aperture of the carb jets and passages, they plug right up with the smallest amount of dirt and the bike starts running poorly. Thanks for the reply.
You had no clue the main jet had a needle jet in n there... Surprise !!!
I have rebuilt my sons 01 TTR90 and it still runs very rich and bogs a 3/4 to full throttle. I have changed the main jet to a 85 I think it is but it still bogs? Anyone have any clue to what I can try next? It even has a FMF exhaust on there so its getting any more air than stock. So confused and tired of banging my head with a solution.
the bog is always an issue.. I found this on a site, but its tough to nail down the exact cause: The “Bog” simply means the engine is not receiving enough fuel when you go to wide open throttle. While there are other issues that may cause similar reactions within the carburetor, often the problem can be traced back to the accelerator pump system. Incorrect adjustment is the typical culprit. The accelerator pump function, as mentioned, is based on hydraulic principles. Therefore, it is essential that the accelerator pump always has tension at your normal idle position. Any air gap here will delay the actuation of the accelerator pump system allowing air to rush into the engine without fuel. The common misconception is that it is necessary to adjust the pump arm to obtain an air gap. This is correct; however that air gap is only at Wide Open Throttle (W.O.T.) not at idle. The air gap is simply to ensure additional travel in the pump arm so it does not bottom out on the fuel bowl. If it does bottom out eventually it could loosen the accelerator pump housing causing a fuel leak. Fuel leaks are something we all want to avoid. Assuming the first adjustment is correct. Then the next step in the process is to add more fuel to the incoming air which is accomplished by increasing the size of the pump discharge nozzle or squirter. This will quite often correct the “Bog” or hesitation by richening the air/fuel mixture when the pump system is activated. If the carburetor works well everywhere else on the track then a bigger squirter might be the only change necessary. Pump squirters are available in a wide range of sizes, the bigger the number (size) the more fuel when you accelerate. Simply remove the pump nozzle screw, lift off the old nozzle and install the new. Be sure both gaskets above and below the nozzle are replaced. If the gaskets are a different thickness the thicker goes under the nozzle and thinner one on top.
What is the part number for the rebuild kit?
dbhatti99 - i used Moose - CARB REPAIR KITS [1003-0329]
when I put on the throttle cable I loose throttle. what could it be
78ginop same have you figured it out?
Alright thx
Can somebody out there please help I know this video is old but I have the same carburetor but mine's has a Welch plug over the pilot air screw and I removed it and put a new one in and now the bike doesn't want to start it just kicks over
Sorry i no longer have this bike but found this info on the web: The fuel screw under the welch plug & the pilot jet regulate fuel for the idle circuit. This is the first and most common passage to get gummed up, since it is the smallest orifice. Also, after the carbs are cleaned or rebuilt, you really need to adjust the fuel screw(s) to what your engine WANTS, not what the service manual calls for. The service manual may be a good starting point, however they are usually too lean. Better throttle response and performance can be achieved with proper pilot jet and fuel screw settings.
You know the thing without the big spring, was that the governor????
Not "without" I meant "with"
The cable with sleeve and spring is the throttle cable.. the stock bike wouldn't have a "governor" , but if the was blocked or super dirt it could act as a governor
whats the electrical connections on the carb for
Anyone help my carb keeps leaking and it won’t stop
check needle attached to float.
Do you still have that carburetor?
Matthew Simms no, sold the bike last year. Thanks for watching!
@@mattdobson123 keep it up, the videos are great
That wasn’t a gas tube you pulled off that was a breather tube, the gas tube was what u pulled off when you cut the gas off
I now have gas coming out of the air box/ air filter. any ideas on what I might of done wrong?
It sounds like the needle valve in the carb is not closing. Remove the bowl from the carb and clean any debris/junk that may be interfering with the needle and seat. If you don't find any obvious junk causing the problem check to see if the needle and seat looks worn. Replace the needle and seat if necessary. Clean the bowl before reassembly. Be careful not to disturb the float level setting. It's a good idea to install a fuel filter between the tank and the carb if you don't already have one.
I wish he could put where he purchased the new parts from
Popeyed Gaming just search for carburetor rebuild kit and model of your bike.. I didn’t want to promote one company over the other.. many different places sell it, thanks for watching!
Amazon, and ebay and alot of others on the net.
I lost the spring for the float :(
Or whatever it is the float came off aswell as like this spring thingy for it but the needle valve didnt
