This Honda CRF450 carburetor needed a few replacement parts and a detail cleaning. It's pretty amazing how many parts there are to a 4 stroke carb compared to it's simple 2 stroke counterpart.

Hey Cameron! I'm back again, to learn some more from you, and another one of your fantastic videos. THANK YOU! This time, we're just preparing to do our final assembly on a new CRF250X Supermoto for my son this weekend! Our bike is fully disassembled right now and we're just about finished cleaning the frame; using your wash/scrub method and the Eagle mag wheel cleaner you turned us on to! We'll be taking our bike's carb apart, rebuilding it, and installing a jet kit-so this video is going to be a BIG HELP in that process. As always, your videos are fun, clear, smart, well-produced and easy to follow. Even us old motorcycle dogs can learn new tricks from you! Well done, again. Take care, Bro.
Cameron your vids just get better and better every time it’s very much appreciated how much details you put in to your vids and very interesting
I’ve been looking for a video like this for weeks! Disassembling a carb for the first time, so the detail helps.
Finnaly a good youtuber WHO show you How to rebuild dirtbike stuff btw Im working on a aprillia 125cc 2 stroke so thanks for giving some tips How to rebuild btw you are the best (sorry for bad english in from Finland so)
This video came in handy tonight. My boys and I are rebuilding the carbs on our 06 and 07 Yamaha yz450f dirtbikes. These are the same carbs we have.
Thank you again...we subscribe and enjoy your videos!
Amazing video, meticulous way of rebuilt, great explainations, wonderfull details on video, and always filmed with joy and happiness, it's so fine, Thanks Cameron !
Seriously, your videos have become priceless to me. I'm amazed that this content is something I can get for free to help me work on my CRF450X. Thank you!
Dude you saved me a lot of trouble. Had my slide upside down and couldn’t figure it out. Thanks and keep up the good videos!
This is my job for today, thought I check YT first for a refresher and struck gold. Cheers Cam
Thank u so much you just saved me from spending a lot of money I love u so much I had idle hang on my wr250f I tried everything to fix it and It was the throttle body slide plate it was upside down😂 thank u again😁👌
Omg, super awesome video! Such valuable content, it's crazy! With this, i now have to confidence to rip apart my crf Carbs... This video will break 1 million views one day. Thanks a million Cameron!!!
ISLAND RIDERS - DIRT BIKE GARAGE legit ive allways been worried to do it now im not too!
you do such amzing cleaning job, wish i had all those resources to keep my bike looking brand new!
Love your videos! Please never stop making ‘em. 🤙
5 minutes in and I’m already learning sooo much! Thank you!!
Thanks for watching man!
I recently just purchased a 2002 Yamaha Wr426F it started once and I haven’t been able to start it I’ve never owned a dirt bike or motorcycle before or have any experience with bikes so this was kinda scary for me but I was able to rebuild it and have it running in less than an hour your video was very informative thank you so much !
Best video ever!! Keep on Cameron!!!
Your tutorial vids are the best on net . Keep up the good work
Awesome vid, took mine apart forgot where one screw went but figured it out as soon as I watched this. Cheers and thanks
It really helped me, thank you so much i have the same problem with the plates upper side down and all the tricks congratulations from venezuela
Thanks for the input/hard work/dedication. Figured out where i screwed up by thinking while watching ur vid.
Thanks.
My bike had this hidden problem and now after watching this video I was able to fix it. 🤙
Wish you had put this video out a couple years ago, I spent a couple days trying to figure out why I put on the plate on the slide upside down. Thanks for the great content.
I ride a Crf450x it’s got a ton of power! Aye I really enjoy your videos man keep up the good work!
Thanks Cameron..your video it.s so helpful, great job and good things from Romania 🤗
Very nice job! I am currently doing this on my 2009 KTM 450 XCF and this is most helpful. Thanks! Cecil D. New Mexico
You saved me many additional headaches by mentioning the slide and plate. Just made the same mistake. Instead of breaking the whole carb down again I flipped the plate and my problem was solved!
I gotta take mine out and flip that plate. Seems weird that it goes in that way
Brilliant as always cam. Would be nice to see you do another one of these explaning the mid body gasket on the fcr it's always overlooked and is a major cause of issues on these carbs 👍
Helped a lot saved me money thanks man great explaining
amazing video thank you so much for the high quality and precession
We use the ultrasonic cleaner for cleaning the precleaned carburator housing and the jets. The small holes get free after that treatment and blowing out. The carburator works like new and is easy to adjust. Perhaps you try. Thank you for the nice vids.
You reinstalled the accelerator pump diaphragm in the wrong direction. Great video
I noticed this as well. Thanks for the comment - Flipped mine before putting it back in the bike - Cameron, this video is priceless~ Thanks
OOF
Thanks so much man. This was so well done and so helpful.
Absolutely brilliant
Cameron seu video me salvou ,estava com uma crf-250 r com problemas de lenta e estava invertida a peça do pistonete do acelerador.
Thank you for making this video!
I’m gonna be taking on this project soon!! Just bought my first dirt bike
Top vid as always bro 👌
Thanks Cameron, helpful video!
Awesome photography as usual Cameron and really easy to follow. Best carby vid I've seen. Hope all is going well with you. I've been riding Yamaha 4/s of late but really turned on by the power that these new 2/s are putting out. HAVE TO GET ONE I THINK! Whats your go to 2 / bike? Dave from NZ 😀
Thanks for your help Cameron
I just rebuilt my daughters 2007 crf150r
Another excellent video. All of your stuff is so detailed and explained. I really feel like I could do it with your help and this video. Thank you Is there any special instruction for the idol screw,or just screw it in until it stops. Also any experience with the 32mm CRF150RB cabs. I have a 2020 that is so hard to get right.
Awesome video. Exactly what I needed! Thank you very much. I will Subscribe for sure.
The info on the slide was great. Did you replace the 3 main gaskets and 2 o-rings or did you reuse them. Thanks.
Great video! How much torque are you supposed to apply to the choke when installing? Thank you ahead of time
Really loved the video. Am in process of rebuilding a flat cr carburetor on a yamaha yfz 450 raptor. Thanks.
Awesome job sir
❤❤❤❤Dude you are amazing keep up the good work!!! Really love your vids you show passion and you are never negative really good job❤❤❤❤❤❤❤
I know this is a few years old now but it was still a good watch. Great job. BTW, for FCR's the R&D Flex Jet air screw is a very good mod for $30.
Awesome result Cameron...would you know if CRF450 carburettor can be used as upgrade for XR600R?
Awesome video. Thanks
Thx a bunch for your vids!
Always have to like the vid even before i watch it because i know its already gonna be lit an i ride a 06 yz 125 :D
Buenas tardes muy buenos tus videos. Le hago una pregunta en mi moto tengo el mismo carburador y esta acelerada que puede ser? Gracias
Awsome work bro.
your brain worth 10 billion dollars for me.Anyone agree?
It's not the genius part of the equation. It's the ability to follow instructions!! AND you are only as good as the tool collection you possess! It's the lack of tools that will make a job seem and look so difficult.
My plate is upside down like you stated but runs pretty good, should i still flip it?
I've packed up my carb and it's on it's way to you for a bath and rebuild buddy!! Much appreciated!! LOL
*whats the difference between a 4 and 2 stroke carb, and does it matter if i use one on the other*
I ride a crf450r and now use stabil which seems to keep my carb clear after I had to pull it apart because of bad gas.
Olá essa arruela de nilon qli do eixo, da guilhotina, fica encostada na parede do carburador ou para a parte de dentro?
Sei sempre il n1
On those fcr carburetors which direction does the O-ring on the slide go
What type of cleaner do you use for the carb to get the grime off...also thx for being so detailed and precise with ur vids trying to fix up my 04 rmz250 ur stuff has helped a lot for sure...please respond with any tips or tricks to get my bike running again👍🏼 best of luck I’ll be subscribing too!!
Is there an o ring for the hot start and or choke?
Thanks for all the tips I’m working on a 07 kx450f I lost the throttle box cover Allen bult got any spare on the web site?
great video but why you didn't check the fuel pump gap? and an oring mod would be awesome too!
What kind of grease should be used for the pulley bearings?
Thanks for the tip in the slide, an easy mistake to make!
When the fuel screw is initially removed is it me or is the washer and oring is out of sequence? It looks like it's metal washer, o ring then spring. Thanks Cameron.
Took mine apart and rebuilt it but Mine is now hard starting. Do you think I may have the slide backwards.
Amazing video, thank you. Now I will try to do the same with your video as reference. :)
Why didnt you remove and clean the float needle assembly there is a plastic filter under there that has to be clean to
Does anyone know where i can get a new float pin holder it feel out of the bike and i cant find it anywhere?
Cameron all my wheels on my throttle slide fall off. Is this bad?
The Excelerator pump you have installed your spring facing out I installed my spring facing in have I done it wrong?
Where to begin . . . thanks for saving my bacon, bro - very clear video. Any trouble with the throttle position sensor at the end?
Thanks!
How far did you screw in the idle adjustment screw?
Do you have a vid on doing crank seals on two smoker
Well done. This is my job and I still found your vid. Interesting Cheers
Do you know where I can buy a replacement accelerator pump nozzle for this carb?
how can I adjust the accelerator pump
I have a 07 yfz 450 that when I'm riding stays at high idle unit I put it in gear and let the clutch out, do you have any ideas on what it might be
Can you help me out with the TPS sensor adjustment. Gary in Millsap Tx.
I've noticed in some of your previous videos that you use an electric pressure washer, cleaning up frames for example, is there a certain brand you would recommend over others for your typical rider that isn't in the market for a gas-powered washer?
Great content as well! Awesome to see another Washington State rider/mechanic!!
Thanks! I use a Ryobi 1800 PSI one from Home Depot
My mocyc yz 250 4 stroke hesitates to start ?
Hiya my overflow on carburetor is pissing out petrol last few times I've rode the bike. The person I bought it off said u need to take it apart and clean it! I need some help What would u recommend thanks
Thank you very much. It's a video that can really help me.^..^
Do you remember what bike that is off? I noticed it has a screw and washer to retain the float valve seat like mine from an '03 CRF450R. I thought the CRF FCRs had a pressed on seat. Great job Cam!
I need a carb for my crf450r how much you charging for one
so itook my carb apart and there is a chip on the round edge near the starter jet... does that mean its shot?
fuel screw came out with the washer on top on o-ring is it meant to be this way
Is this same carb used on a Yamaha WRF450? Looks just like it.
I just went through the carb on my 1981 yamaha xt200 today and God damn is it simple compared to the 450r carb
It would be perfect if you had also made a video of how the hoses of that carburetor are connected to which places they are directed.
Why did you put the rubber band of the accelerating pump upside down?
Hopefully I get some advice. I rebuild the whole carb and cleaned it for my yz450f. Before it would leak from the carb over flow tube (the one at the bottom of the float bowl) constantly when I had the gas turned on. And still does this even after a full rebuild. Any advice? Thank you
Mine did the same thing. Did you figure out the problem?
How do I rebuild my 2009 crf 450 throttle body??
I have gas pouring out of those 2 little holes from the intake side. Any ideas? You can see it pretty good at 9:12 Great vid btw
I really like the informational video I am a tech and have been thinking about making a channel myself recording all the bikes I work on...your fuel screw assembly was in wrong though I'm not sure if it was someone else or you that out it in there last but the washer and o-ring go in the reverse order it goes screw washer o-ring in that order on every single car wether it be an air screw or fuel screw it doesn't change
