I thought I was the only one who thought these were a bugger to install. Very clear Video Cody! Love the spray and grease technique. 👍❤️🇨🇦

Had to give up on fixing my 78 cb750f ss . I found a local guy that actually wanted to help me keep the old bike get back on the road . New head work and rebuilding the carbs too . Took it to the shop Friday . When I showed up Saturday to agree and sign the work order the motor was already out of the bike . He said he had a great time working on something other than old Harley . If it wasn't you this guy is a close second . Thanks for all the great tips you share here on your channel . Cheers 🍺 Cody .

I have spent hours trying to reinstall carbs in a V-twin.... I can’t even imagine an in-line 4. When they finally slipped in I audibly said “boom” at the same time you did. Lols

It’s a magical moment even if you’re just watching someone else doing it.

Cody is rebuilding my carbs this week . That's why I'm back . Totally stoked !

Another important thing to check is the alignment of the intake boots. You can put a straight edge on the front then the top of boots to ensure they are perfectly aligned. Great video

Trophy to you for explaining this sensitive subject so well,
Specially showing how to make sure the bike should not move forward,
Thanks so much Cody, I wish you were in California

Just did mine today. 1991 Honda cb750 nighthawk. I used 2 clamps one on each side of the carbs. Went in like butter.

90° pick = machinist scribe, harbor freight, welding supply, or online. A must have in most tool boxes.

very cool. I have my late dad's 83 750 Nighthawk. Carbs must be cleaned. I'm going to do the install and re-install myself. Look for somebody to do the actual cleaning. These vids getting me through this. Thanks.

[willmoua]

I've noticed in previous videos that your nighthawk has pods.
Can u show a video on how you went about jetting and adjusting mixture screws, jet choice, etc?

[sthildas]

Thx Cody my 500lb+ Honda fell off my mover, onto my knees, staying safe. 🇬🇧🏍️

[balmeros]

Been waiting for the install, helps me a lot. Now I just need to get to work on my NH750.
Intersted in the instruction at 40 bucks.
I also have a CBk7 which also needs carbs installed !
Thanks M8 I'll look on the site.

Great video. One thing if you notice the little dot on the diaphragm cover screw that denotes they are not Phillips but are instead JIS (Japanese industrial standard). You may want to invest in a set of JIS screwdrivers. Hard to find in the states. I had to get mine from Japan. I have never rounded out one of these screws since buying those screwdrivers. Love your material. Keep it coming.

I assume you found the rubber debris near intake #4? - Excellent Vid - I like the center stand awareness. I rebuilt my 79 CB750's, and plan now to rebuild my wife's 81's. I have no lift, and for the 81 no airbox. I ordered the colors and clamps and rebuild kits. And then figured to rewatch your vid - thanks - different carbs, different bike, but very much the same thing - When re-installing on my 79, Throttle cables and Choke cables were also attached first, and then the same slide time in and roll then down and in.

Thanks for the reminder of the silicon lube - wd40 should do fine. I do not recall doing that last time, but having no lift, I recall having the bike between my legs while negotiating the carbs into their original collars on the 79 .

For the 81, I figure it should be easier using new collars. I also don't think I will go for breaking them apart if the shafts are okay. Right now mostly float sticking from rusty gas. So I figure to get the internals working and then degunk the external for a visual, and if okay then reinstall.

I will review your other vids - thanks again -

Cody mate, i've spent so long and so much money on the carburetor, installing it and taking it off cos it was done wrong, after watching your video, i installed it with super little effort, thanks for the tip sir, keep up the good work.

Perfect, no impact drill required could strip out screws do by hand if possible. Love the video thank you brother

[kiptonyost]

Used to use hockey stick to take carbs off/on. They work great w/o damaging things.

[beebeebearbear]

Great video Cody. I have my 1985 Honda 750 Night hawk to do. Carbs need a good cleaning.

[BrandonLund]

Fellow YouTuber can you help me out. I have a 2002 XR100r carb. There are 2 brass tubes that protrude into the carburator intake opening. The one at the bottom of the intake opening i can't blow through. The one next to it I can. Should I be able to blow compressed air through both of these tubes?

[lazer]

I have an 80 CB 750 f. I have become quite good at installing and removing the carbs. have tore them apart cleaned them several times. runs for about 30 seconds and quits. Have compression, spark, spark under load also. Plugs foul except no 4 stays clean. I'm about ready to give up. Had this bike for 3 years and still haven't made it around the block. Thanx for all your great videos .
