Nice😊

👌👌👌

needs the airbox pod no good for diaphragm carbs

Stock (us) is #100 main #68 primary jet and #35 slow jet…you went up to a #120 on the main?! And 80 on the primary? What about the #35 slow jet? We are talking about a CB750F with stock keihin carbs? I truly want to know as I am struggling with my stock carbs. Very free flowing exhaust, pod filters…jet kit #108 mains stock #68 primary and #38 pilot jets….2 1/2 turns out on the fuel screws…carbs synced. One washer under the stock needles. “Burbles” when transitioning from off throttle to a small amount of throttle at cruising speeds….runs well up to 8000 rpm then stumbles and will rev no farther…very frustrating. Need to pull them off. I cleaned them but didn’t check float height. Definitely worse as engine heats up from cold. Not sure if I’m need to go up on the mains…I have #105….#110 and #112 to try…the #110 and #112 are considered stage 4 and 5….#120 mains are crazy big from stock!!!

You’re running 120 main jets on a stock set of CB750F carbs?

Hi, what exhaust do you have? I've a 1981 cb750f and I'd like to improve the sound. Thank you

Are those the original handlebars?

very good! I have tried on my 750 f boldor jets from 120..124..128 ... but I could not make it go well maybe because I had open conical filters. can you give me some advice?

I’m just about to buy one. Unaltered. 30,000 k on it. Has some crank noise vibration. Yours look great man.

Looks like a Honda with a Suzuki tank😂😁 Looking good!

Hey, Currently cleaning up a set of BST34SS for my 900f. pretty much stock. CBR coils, relay mod, 4into1. Got a Keyster kit with all new stuff ready to go in. What jets did you start with? Mains? Pilot? Air jets on the top? thanks great bike

Very 👍 good, You have alot patience going through traffic. You look you were having alot fun. Were you screaming 😱 in your helmet ⛑️. Cause thats exciting for the video. What kind of bike do you have on that track. Al

Jim’s the man!!!

Was this bike modified to allow a one down four up gear pattern please? Was the standard shift pattern one up and four down? Thanks.

What's a motor build like this usually go for? Sounds wonderful. Got a real gem on your hands!

nice bike!!

Did you make any adjustments to the slide needle?

hey mel im with you on everybody and their opinions are on the CB 900 that I have velocity stacks on and it runs like a champ but I've came across an issue with a part Breaking and now I'm running 750 carbs on my 900 but I would like to rejet them the way you did so that it would run like that what can I do to my 750 carbs to run on my 900 to make an improvement

Hey great video!!! A lot of the Honda CB DOHC people have a notion that you can get the bike to run right without the airbox or the stock header/pipes so Im glad you made this video. I also have 79cb750k and will be running pod filters and the carpy 4 into1 small baffled exhaust/ collector. I do have a supertrapp as well, probably similar to yours- and I will start my jet choice with what you suggest--so thanks for that!!! My only question is the needle position. Im assuming you left the needle clip in the middle (stock) configuration? so it would be 80/120/2.5 turns out/and stock setting for needle clip.....Thanks for the help and advice!!

...

What size jets please?

What altitude are you at I'm in Colorado (in the 5000-8000 ft range)

PS It runs the same with either filters or none.

Hey Mel, doing same thing with my 81 900f. However it was sitting a while.The last time it sat the carbs needed sonic cleaning as slow jets are pressed in on 81's and can't be properly cleaned. Now it doesn't wanna run for long (10 sec or less & 3 cylinders ?) but only with starting fluid. It ran fine when it was parked. 1 1/2 years ago.

Where can I find the jets you used? And what size are they?

Hey thanks for the reply one question do u have to drill the slide hole thanks many

Joe CARBU...There are PODS on carbs 1 through 3. I don't have a POD on the number 4 carb, because I wanted to show you all, that the slide lifts and falls as I twist the throttle. No sense in filming just a POD.. A lot of DOHC owners believed that you need a stock airbox, to run right...

You have no filters man .Why talking about pods ?

You should make a video on how to do this mod. U will be famous lol

Well done Mel. The first start up after a rebuild is always a bit nerve wracking. You will have yourself a lot of fun with the extra grunt. I bet you can't wait for the next track day! Enjoy the fruits of your labour.

Okay Mel this is awesome because I've heard such bad news about pods on cv carbs. I see you said what your jets are but what kind of pods are on there and how did you set them up? Thanks

What size jets did you get and is your exhaust stock?

Are you using dynojets stage 3 with the original keihin carbs?
