Great video bro. I have been struggling with a 07 CRF450R. Your video was the solution to my problem. Great job. Thanks!

[@Kimsand520]

Thank you for making a video about this. i have been struggling with my 08 YZ 250f for some time now with a bad bog of idle, replaced ALL the seals/gaskets/orings/accelerator pump in the whole carb except the mid body since almost no one talked about that, everyone just yelled that it was the accelerator pump which already was replaced. After having the carb apart for the 5th time in a year(what a pain it is to remove on this bike), it finally runs correctly after replacing the mid body kit!

[@nikolasntanos6847]

One of the best videos for carbs bro...You can understand how it works through all that process of cleaning! Thank you!

[@geogineer]

Dude, thank you! I know this is ancient- but this is the first time rebuilding an fcr. I ordered the rebuild kit and was like wtf!? What about the accelerator pump diaphragm and the mid body gaskets? Then I see a ton of dudes not even worry about it and just use what's in the kit. I say do it right or just don't! Anyhow, thanks for the video.

[@soulgivesoul07]

i butchered my carb trying to adjust the accelerator jet because someone before me put it in to where it shoots the stream facing the airbox. luckily i found one on ebay. great video man thanks for posting!

[@neomustafi5744]

Nailed it💪 a have been searching for videos like ages. Your video and the one from Rocky mountain Atv are the best out there that explains everything like 100%

[@11GalleryATV]

Thanks for this! I was trying to figure this carb out and you helped me a lot! Thanks!

@6:48 “I’m just going to take out my little probe here”😂😂😂.

[@bbpritt]

Hey, this video is super helpful, thank you! I am rebuilding the carb on a drz400 and ride from about 5,000 to 10,000 feet. My main jet (142) and starter jet (65) seem to be stock but my pilot jet is 45 instead of the stock 38. Would you recommend any changes to how I have it jetted? Also, is there any harm in reusing the needle and some of the jets if they seem to be clear and clean?

GREAT VIDEO!!!!!!

[@AodanKeenan]

LOVE YOUR IN DEPTH VIDEO! I NOTICE THAT YOU "AIR CUT OFF DIAPHRAGM/COVER" IS MISSING! EVEN IN MY 2006 OWNERS WORKSHOP MANUAL... IT IS MISSING! IS IT DELIBERATE?

[@pmfilmsUK]

Fantastic

[@whatsit2ya247]

Great video! I've never replaced those mid body gaskets before, I don't know why they're such a mystery? Went to my local KTM dealer to get some, they don't stock them, he Say's; I Duno man, we never replace those, I don't think I'd do that if I were you.

[@claytonmotos2816]

I’ve honestly never heard of them until I found the kit to replace them and even finding that was a struggle. They have made all the difference in builds I’ve done before so they are now part of my normal carb rebuild procedures.

[@pillcosbyandtheroofies5140]

@@claytonmotos2816 I'm in need of your help. In your video which is very informative and by far the best video I've seen on this carb hands down. In your video @ 14:48 after you break apart the mid body and talk about the shot if gas the carb gets in the combustion chamber. My carb does not have that nipple. Can you plz point me in the right direction to purchase one. Thanks and I appreciate whatever help you can give.

[@claytonmotos2816]

@@pillcosbyandtheroofies5140 Hey man I’m on the case. Pretty sure that part is pressed in but I have an extra carb body that’s got one in it. I can try to remove it but if that doesn’t work i’ll post the carb body on my ebay store and send you a link.

[@pillcosbyandtheroofies5140]

@@claytonmotos2816 hey yes it is pressed in. I'm not sure why it has a slot for a flat screw driver like the other jets but that is absolutely the little piece I need. Thanks for looking into my problem I appreciate you and keep me posted on that link if you can't press it out. Thanks again!

[@TheChaz81]

If I send you my carb and pay you would you rebuild it? Clayton Carb Builds! Its got a nice ring!

[@MrOukisee]

Safety torx.

[@kenedshog]

I’m in the process of cleaning and replacing the jets in my carb and was wondering where a jet went that I didn’t recognize in my reset kit. It turns out to be the starter jet which was missing from my carb. Not sure why it was missing since I bought the bike used. Maybe it will run better after I get it all back together.

[@liisatuohiniemi-tikkanen2607]

where can i bye this mid body casget kit??? there is no oem number..?!?!? i have kawasaki kx450f 2007

[@josehurtado6751]

Awesome man thanks for the video , I am wondering how I can unplug the tube that shoot gas into the cylinder the one u pointed out you called it the tube , i see no fuel being shot so also how can I make fuel come out of there with out reassembling the carb into the motor? Or do I need to have it installed

[@claytonmotos2816]

If you’re talking about the accelerator pump tube then you need to disassemble the mid body and then you’ll find the tube screwed into the main body. Most of the time it is seized so I don’t try to take it out. I just blast it with carb cleaner and compressed air. Also make sure that your accelerator pump diaphragm is installed correctly as that could be the cause for no fuel being shot in.

[@SushinAuto]

He was talking about the little tube sticking out at 14.58 in your video. That’s shooting gas. I hope that is replaceable. Mine is missing or broken. I hope I don’t need to buy the whole carb just because of that.

[@SushinAuto]

At 14.58 that little tube shooting out gas, is it replaceable, because mines broken, or is it part of the carb body.

[@claytonmotos2816]

Hey thanks for the comment. Yes the part has a part number however it is not purchasable through parts suppliers, I have tried. The only way I have found to replace a broken one is through buying a new carb throat. That particular jet is pressed into the throat and must be pressed out. Be very delicate!

[@SushinAuto]

@@claytonmotos2816 oh man, that sucks. Ok thanks for responding

[@MxStRider]

Not to bag on your method of madness But... the Use of an Impact screw driver on Carb Slide seems Strange to say the least. Hey U gotta Improvise right?
