carburetors

Hey ya'll I'm a noob to this forum and need help. I'm rebuilding my carbs from my 79' CB750k and I'm missing a vacuum slide (diaphram?) spring. Part # 16050-443-701 as Honda lists it. The part is out of production and i can't seem to find one anywhere. Is there a replacement that i can use or...

I have inherited this 73 CB750 and I'm in the process of bringing it back to life. I bought the carb rebuild kit and have the carbs off. As I was operating the choke lever I noticed that only the #1 choke plate would bottom out, the others would not and kinda float loosely. Pretty sure they...

Hey yall, I have a 82 Honda CB750. Theres no fuel line to the main jet. Petcock to hose and clamps? Which petcock? Its the only thing (i believe haha) that keeps this thing from running. Ive been told about diaphram vs. gravity fed... Sounds like i'd like to switch to gravity fed but i have no...

I have K model carbs, and an F model top end. Which intake boots will work best with this application ?

I am looking to replace a primary maijet emulsion tube I had to drill mine out during the carb rebuild because it was stuck. You guys know who sells them? Thanks,

Hey Guys, I'm in the middle of a rebuilding a CB750 1981; This is my first ever build and It's been a whirlwind of forums, google, youtube and a local motorcycle shop to get me on track to this point. However, I've hit a bit of a snag; the bike wont start / fire, and I wondered if any of you...

Hey guys, Bought a 78 CB750F from a relative and its been a ton of fun! Unfortunately two of the four needle jet holders are bent to crap and I have had zero luck finding replacements. Any help or direction to the right holder would be wonderful!

I have inherited a '78 CB750K, and have just completed a bunch of work to get the bike to the point where it *starts*, which is encouraging. But, several of the carbs are leaking through the overflow tubes. I've taken the carbs apart a four or five times, cleaned them as best as I could, but...

Since this bike is missing the Air box,.,Should I replace this filter system .,.Or do some of you go with a different set up.? Thks Keith,.,:)

I am wanting to switch my stock airbox to pod filters. What jet sizes do i need to go up to, to be able to run them?

Hello, So I am rebuilding my carbs on my '81 CB750F and when I disassembled my carbs I decided to check the accelerator pump. Little to my surprise I had a tear in the diaphragm. So I ordered a new pump assembly and when it came it had a black pump piece that was not in my carbs. I have...

I really need some help here. As you can see in the photo, my carburetor cable and linkage is obviously very misaligned. It's probably off by a good quarter inch or so. I see no way to correct it and I see no room for adjustment from side to side. Anyone have any ideas and thanks in advance.

I will be very thankful to get these carbs back together and her my baby roar! Happy Thanksgiving yall. Thankful for this forum and the wealth of knowledge ive learned from yall.

ok, i got fire in the hole so now i have to pull the carbs and clean then see if i can get it running well. but i'm going to go with pods and the bike already has a 4-1 header so i need to know what is the stock main jet size for my bike. someone may have already changed the jets but i won't...

I have a 1980 Honda CB 750C. When I switch to the reserve supply, the bike dies. Funny thing is that even though the engine doesn't seem to be getting fuel, I can see gasoline flow through the filter when when I twist the petcock to the reserve supply. Once after the bike died after I tried...

Hello guys and girls, First time post here, I'm hoping the wealth of knowledge on here can shine a light on my problem, so I have a 1982 Honda CB900F Super Sport.. Beautiful bike I've had the privilege of owning for the past 8 months, great to drive once she's over 4000 rpm but anything below...

Hi i run in cb750 k 81, i´ve a two carbs vb42ag and vb42bd, both in bad condition? Which is the best what differences do they have? Can i assemble a set of both carburetors? Thanks

Hello, I Have a 1981 cb750k DOHC, the bike idles a little higher than normal and revs fine in neutral. But when i put it in gear and go to ride it starts bogging out and sputtering at about 1/2 throttle. Recently i put pod filters on and it ran like crap but then i raised the needle in the...

Hey guys, Trying to get the bike tuned a little better, Right now from at Idle when I give a large throttle blip there is little response/ the bike almost dies. I cant be a bit more gradual and its ok. Same for once I'm at a bit higher RPM. Fuel accel pump is working. Currently only non...

Read a lot on here about these bikes not running properly with pods. The new-to-me 1980 CB750K I acquired had the dreaded pods installed and ran simply awful! Luckily for me, the PO kept the stock airbox and boots. So.....I spent a couple hours this afternoon replacing the pods with the stock...

New guy to the forum, Just purchased my 74 CB 750 from the original owner, he was a wonderful guy in his 80s that just had a hard time letting it go. He would start the bike often but it had not been ridden for years. I have had the carbs rebuilt and syc. replaced the plugs and coils and wires...

Just now getting around to installing the airbox on my newly acquired 1980 CB750K and cannot figure this out. The airbox has 2 hose barbs and I do not have any hoses to connect to them??? The pictures show how the crankcase hose is currently on the bike. I am thinking that the previous owner did...

Refitting carbs to the engine with the engine in the frame had me pulling my hair out, there's not much left now! Problem was the tubes were new and tight and inflexible. I just could not get behind them to push on to the cylinder head. I eventually came up with this idea of using ratchet straps...

So, this is it, the last thing to do on my build before the bike is up and running, and it is stumping me. I rebuilt the carbs when I rebuilt the top end of the engine, and thoroughly cleaned them and bench synced them at the time. I am running pod filters and a 4-1 exhaust, and when I first...

G'day guys, just throwing my 80 model 750k back together after pulling it all apart, and have a little problem. I rebuilt the carbs, but having put them back on, I've attached the throttle cables but the throttle doesn't actually work....when you pull the throttle it doesn't return. I have...
