CB750 Nighthawk: Carburetor Removal

[@taylorevans2693]

Started watching this video thinking I was going to have to pull the carbs to install new throttle cables, but what you did with the bracket will save me a ton of time!

[@stevenwarner7348]

You are my new "best friend"! This bike, 1995, 30k miles, lost keys, no title, sketchy story, very very little money, 800 miles down, 800 miles back, sketchy trailer, George Washington Bridge, broken axle, Lowes for a new trailer tire, a fix on the highway. A Southern state (sort of).... And so. I now believe the sketchy story. Out of a container where it had been for (at least) four years. Black too, all original. The local Police Chief is helping ~ clean VIN~ Just ordered a Corbin seat. Digging into the keyset ~ one bolt out the other stripped, today's project. So you have my full attention. Every nuance ~. I'm going to start wearing wrinkled shirts. No problem . Now I will watch the rest of your video. Thank you for sharing this. New Hampshire. 〰✨👍✨〰

Hi, I just wanted to say I really appreciate this video. I picked up my own 91 CB750 Nighthawk as I grew out of my 2015 Suzuki DR200S that is my first bike. I have a lot of experience wrenching on any fuel injected car, but absolutely none with motorcycles let alone carbureted so this is very helpful. I hope you are doing well. Thank you!

[@ViseAce]

This video really helped me I just bought a 92 cb750 as my first bike and this helped me immensely thanks!

[@mikegermain7033]

Your videos have been a great source of information. My retirement plan is to tinker with old bikes but leave the tech stuff to professionals like yourself.

[@menom7]

LOVED this video Cody,as I have a 2001 CB750 Nighthawk,but have NEVER EVER tried taking the carbs. off of it!!! To help maintain them since I've owned it,when it comes winter-time and time to put it away........I put premium fuel in it,and add the right amount of Sea-foam and then let it run long enough so that it fills all the bowls up with fuel/Sea-foam,then that's it!!! Have never once had a starting problem or carb. problem with it yet!!! (Knock-wood!!!) Anyway,I'm SURE all of us viewing this video,would SO VERY MUCH Appreciate one where Your actually TAKING APART,CLEANING and RE-INSTALLING these EXACT SAME CARBS. you took off of this engine,so that everything is done in FULL here!!! If You wanna do that in a 2-3 part video-series,DO IT!!! I beg of You,as reading these comments...........I can already TELL how MOST viewers would LOVE to watch You do all that I mentioned above^^^......Including MYSELF!!! Lol. Thank-You!!! :-)

[@flexjay87]

Had a pristine 2000 black Nighthawk 750 for a brief time, sold it last summer, but kept my Honda ST 1100, which i love .

[@ArcAngel572nc]

I'm a Harley Davidson Technician and I've been paying attention to what information you have shared and how you've conveyed it to other who generally don't have knowledge of the process. Anyway, you haven't done too badly. I nearly had a stroke though when you said to use a razor blade to clean up the intake boots! Can you imagine the number of ones that ruined perfectly good boots because of that slip of the tongue? NEVER use ANY sharp instrument against a soft material, especially a sealing surface, when attempting to clean up a part!! Don't use a sharp scraper when removing gasket material from an aluminum engine part like a cylinder head, rocker cover or oil pan either. You will ALWAYS gouge the mating surface and create a potential leak. Use a gasket removal solvent first to soften the gasket material and follow that with a DULL gasket scraper and you'll end up with a properly cleaned part that's ready for reassembly. As for the intake boots I would spray a small amount of carburetor cleaner on a shop towel and thoroughly wipe the insides of the boots and once that's dried I'd do the same thing again using a silicone spray lubricant. Keep up the good work but be mindful of your audience and there capabilities.

[@jamesjpearl]

I'd love to see the video of you putting them back in with the airbox! I can't get the airbox to sit nicely on the carbs. I have the two left ones perfect, but the right ones are not as flush!

[@sfess002]

Cody thanks for all the helpful videos! I’ve been watching them ever since I picked up an ‘85 Nighthawk 650 a few months ago. I enjoy learning from the trials and errors that come with wrenching on a bike. Along with the satisfying feeling of fixing something correctly.

[@MizMods]

"Grab 'em by the bowls." What a great line. 👌

[@TheMotorcycleMD]

HAHA!

[@yourejustintim]

Sounds like a good tee-shirt

[@AlexJimenez-cc3cs]

I have a 82 750sc that I pulled carbs from. If you think that's hard wait until you try to put them back. And Cody sure is right on about if there NOT RIGHT THE FIRST TIME time you will get a lot of practice and a good dose of frustration. Thx Cody Happy New Year.

[@matthewchestnut983]

Thanks for the suggestion on getting the 2000-03 service manual. I have the 1991 service manual for my 1992 Nighthawk 750, always looking for guidance on servicing this motorcycle!

[@Pifferfish]

Got my carb kit, attempting this next weekend on my 1985 Nighthawk S. Been dreading it, but it's time.

[@yourejustintim]

Where did you get the carb kit? Im doing two 1984 nighthawks. Dont do ebay or Amazon.com unless fully vetting the company/product.

[@Pifferfish]

@@yourejustintim I went to ebay. No one else had the sets of 4, and were charging insane prices for 1 carb. Unfortunately it doesn't appear to be a really complete kit, but should serve well enough for my purposes.

[@michaelhilton877]

Thanks for sharing this, it helped me tremendously!! I'll add that getting them back in was a bitch. A tip that helped me - I used 24" wood clamps to pull the carbs forward and tightly into the intake ports and held them there while I fitted the rear airbox boots back on. Made a huge difference.

[@kikobaliko3051]

Happy new year! Thank you for helping me with my bike.

[@tknadin]

Nice on mate. I hope you and the missus had a great Christmas and a great new year.

[@bretearwood7027]

I will never be able to get rid of my 92 cb750. I love that bike so much It was my first and it will be with me until the end. Went to a breadbox filter because I absolutely hated putting those carbs back on.!

[@timothyharris1125]

Got pod filters on mine

[@whiteboyskittytv5840]

HONDA!

[@AsheTracks]

Im having such a hard time getting the carb off the gasket mounts 😤😤😤

[@blipco5]

Sometimes if I'm working on the bike on the side stand I'll strap or tie wire the stand to the front frame so that it won't fold up if I push the bike forward. Same with center stand.

[@TheMotorcycleMD]

Clever!!

[@unspokenhour]

Ngl man I love your videos you making me want to do my carb on my cb750 and get a manual, I wanted to see the bike because it was my project😂 but I work 2 jobs, so I figure I didn’t have the time for all that, but your videos explain everything so perfectly man, answers all my questions and give a amazing job at making sure your audience has a great understanding of what going on at all times, such a underrated channel, I think if I keep the bike long enough im going to clean the carb and remove the spark plugs put some new ones on and try to get that fuel to air ratio good, i actually just watched your video on that, I was curious on what exactly you did to take out the tank so I came to check this out, but currently im going to do a oil change, replace the plug and seal, filter, replace the oil seal, also I want to replace the forks but I don’t have a bike stand and I want to sell this bike eventually and get a new ride

[@TheMotorcycleMD]

Thanks for the compliments man! Sounds like you got some work to do 🤙🏻 Get it done!

[@gigmcgig8995]

Good concise informative video from a straight shooter no bloviation good video thank you

[@ikutiap5923]

To rip out the carburators you can use a heavy axe. Great video thanks for explaining.

[@BrandonLund]

Another great video! Thanks for sharing.

[@vernondemaree7289]

Happy New year!!!!! God bless!!!!!

[@jojojoseph2469]

Thank you for all content.. I recently picked up a 1984 Honda night hawk CB550. I’m having troubles tracking down parts. Any chance you or anyone else in the comments may know if CB650 carb parts are compatible with the CB550 carb, I’ve searched hi and low for information on compatibility as well as suppliers. Looking for complete carb rebuild kit, everything included/individually if I have to!

[@NomadicMedhunter]

extremely helpful video thank you brotherman, got to do this soon

[@paulbrady8309]

Thanks Cody, this was a big help!

[@caroltenge5147]

whould you demonstrate how to remove the carbs and rubber intake pieces on a 1995 honda 650SC. I think they built the bike around the carbs. Please help.

[@briansmith2131]

This is great man thanks and Sub. I have a 97 Nighthawk 750. Hard 2 find shit in the CB 750s.

[@vernondemaree7289]

It's been a while !!!!!!

[@ericvalchev8411]

Hey man, great video. Thank you 👍

[@Khime84]

Hey Cody I really like the video, thank you very much. My 93 750 has been sitting for about a year and a half now. I did a carb clean and I'm having a lot of problems putting them back on. Could you please make a video of you putting it all back together. Because I cannot seem to get the two center flanges back on.

[@bretearwood7027]

Use a ratchet strap around the engine and around the carb rack to help pop them back in.

[@Khime84]

@@bretearwood7027 I will definitely try that this weekend thank you for the advice man.

[@YannFromIATA]

Hi Cody, Would it be the same procedure for a 1983 CB650SC Nighthawk?

[@adjbob56]

Clearance to pull carbs can be increased by detaching rear inner fender, to allow air box to move back. Factory manual shows 2 bolts for rear inner fender, the forward part of that plastic inner fender can be shoved down (detached from frame tubes) which helps. Removing the 2 bolts at back of that inner fender helps more (nuts for those bolts are behind the small tool kit). The Factory manual is very cryptic on this process, but at least mentions the rear inner fender. The Clymer manual is much more detailed for most of the procedure but fails to mention detaching the rear fender, which was vital for me to get enough clearance to remove the carbs today.

[@eduardoperez7797]

Hi thanks for the videos bro have a 92 backfires do you have a video on welsh plug or lean bolt adjustment for this bike? Thanks in advance.

[@yourejustintim]

Thanks for making these videos. Whats your opinion on installing pod filters rather than putting the air bix back on?

[@Triumphandme]

Hi great videos buddy many thanks. I have stripped my carbs on my 1994 F2. I have found that the 2nd and fourth carbs have bigger pilot jets, 112 instead of 110. You don’t happen to know if this is usual. The bike is a 12k miles beauty and pretty untouched. I’m wondering if they should be 112s for the middle two carbs to help with cooling? Any tips would be great. Regards Al

[@nine60xray18]

Love your videos man. Super helpful and clear . I look forward to your new uploads. You mentioned spray painting the rusty carb rack/rail, I was wondering what kind of paint / color you would use to do so)

[@TheMotorcycleMD]

Will probably just do a basic black spray semi gloss.

[@gaultjames]

Love the videos! Any info on the aftermarket fuel filter, and does it help with ethanol in fuel?

[@TEIRO323]

Can you remove all the extra piping in the California model 97 cb750 ac, cap off all the vacuums and have the bike run right?

[@numptyadventures9207]

I've same carbs,it starts fine & idles great, as soon as you give it has it chokes& won't rev up, I've taken apart& inspection all seems ok, any advice&clues. Cheers

[@sampitrone]

Excellent!

[@holeshot1721]

The main fuel line is obvious but were do the rubber hoses that are inbetween carbs 1&2 &also 3&4 go?

[@AICD1999]

Stop folding and start rolling. No more wrinkles and you will fit more in the drawer.

[@GoldensRule45]

That is close to my suzuki GS650GL and it took me hours to figure out how to pull them out I still need to rebuild them and want to never reinstall the airbox and use single pods. Will I have to completely re jet the carbs to work, or can they work ok as installed by adjusting the carbs?

[@whiteboyskittytv5840]

Can I remove the carbs and send them to you to clean?

[@stonerdustinn]

What was that look you gave when I asked about what jet sizes to use when straight piping the 91 nighthawk CB750 is it bad for the motor or does it sound like crap?

[@son1nekortez464]

Thanks. Great instructions

[@chrisstevens3801]

Hey Cody! I've watched a bunch of different videos by you regarding jetting. I have a 1996 CB750 nighthawk with an open exhaust and pod filters. Bike is backfiring on Deceleration and hesitates when give a lot of throttle at lower rpm. Runs pretty decently top but seemingly lean. From watching your videos I need to go with a 127-130 main jet up from the stock 112. Stock pilot was a 35 and Im just bumping that up to a 38. Does this sound right? I ordered a cheaper kit from HondaJetkits and got skunked. they sent me pilots, mains and needle shims. Everything looks correct except for the pilot jets. They look like fake/cheap Keihins and the holes in them (supposed to be larger 38's) are smaller than my stock 35 index pilot jets. Love your videos! Any pointers would be greatly appreciated! Sorry for the throw back comment!

[@michaelmassey7744]

What are those hoses inbetween carbs 1 & 2 and 3 & 4?! I cant figure it out, I have the cb650 but carbs look identical. In the manual it says they're fuel hoses? But I thought it's just one fuel hose in the middle that splits the gas to all 4. Please help lol

[@NextLevelAutoDiagnostics]

The bowl drain screws on my Keihin VE54 point left on #1 and #2 and point right on #3 and 4. You state only one should be accessible from the other side?

[@yourejustintim]

I went to your website. Will your carb rebuild videos cover 1984 650sc carbs? I know it say "most 1980s" and 750s are basically the same, but id thought id ask.

[@TheMotorcycleMD]

Some of the early 650 carbs use the aluminum top/metal slide piston style carbs. If yours use the rubber diaphragm style, then the tutorial will fit you just fine.

[@nibrocnoel3240]

Is there a way to open the choke manually? I have a 85 nighthawk 650. My choke cable broke and I'm trying to get my bike back to my house. Changing the cable where I'm parked is not an option.

[@wildwest9395]

[@vladtepesiii4145]

I have a question about carbs. i have a 93 nighthawk and i wanna know how to choose a slide carb rack

[@theflyer4916]

Hi, My #1 carb has been leaking from the bowl. The carb drain bolt is in tightly however I noticed the #1 and #2 bowls were reversed(#1 bowl was on the #2 carb and vice versa causing the drain screws to be facing each other). Being the #1 bowl is shaped different from the rest, could this have caused the leaking?

[@bogdang4408]

Super. Nic dodać nic ująć.

I have a 80 cb750 got the carbs jetted thinking that was the problem it won’t rev up and is blowing flames out of the exhaust... it pops out of the carb I’m stumped have any idea ??

these Nighthawks are getting very collectible, they are still very reliable and can easily get 100k miles if you dont run it out of oil. just solid

Hi Not a Honda but a 2005 Yamaha FZ1. I don't ride my bike to much. Once two time a month. After setting for a few weeks when I start her fuel leaks from the carburetors. It only leaks in till I start riding than it stops. I got the carburetors off from the bike clean them change gasket bowls the floting pins and the baskets and all the other O-rings that came with the carburetors rebuilding kit. I still have leaking fuel problem. Like before just when I start the bike, eventually it stops. Any advise? Thanks

Tbh this guy talked way to much video could be half the length. We want to know how to take it apart not how long you had it or how ugly it is. Where is the old yt that would be like do this then do this and quick tip be careful when doing this. Straight forward easy how to do videos that have high detail no skips just fast forward when it needs to so you can watch it if your missing something.
