Hi, sorry I don't have a history posting here, but I can verify my identity, and the builder can vouch for it as well. I've put a lot of money into making this a start-on-the-first-try at the start of the riding season kind of custom bike (our bikes hibernate up in Canada). You'll see lots of...

Moving on to other bike projects and need to make space in the garage. 24K miles on this 1980 CB750 Custom. Bike runs pretty well, but at the moment the original Keihin carbs need to be cleaned/sync'd before it'll start. Relatively new 4-1 exhaust w/no rust, side covers intact, and still has...

Hey everyone, I have an ARD magneto that I removed off of my ‘72 CB750 several years ago. I’m wondering if anyone here would be interested in buying it or if I should hang on to it and maybe use it on a build project later down the line. Let me know what you think and how much it might be worth...

Hello I have a restored Honda CB 750 Custom from 1981. The motorcycle has undergone a major renovation. Chains with tensioners, pistone rings, valve seals, pans and bushings have been replaced in the engine. The problem is that when I start the motorcycle on the choke, even on warm days, for...

Hey, a little late into my build but figured I'd post pictures to date for everyone's viewing pleasure and maybe get some feedback that helps me along the way (btw, thanks to everyone who's helped thus far!). Quick summary: purchased two 1980 Honda CB750Fs back in October, both were in pretty...

Hi there, I have a 1976 CB750A and he chance to buy a rebuilt CB750K engine. Can I transplant that engine into the frame of the 750A? I would have to add an oil tank and perch for the clutch, but will the motor mounts line? Thank you!

Hi everyone, I just purchased this CBX750F 1984 model here in Australia; compliance plate/frame number (RC17-2005966) 3/1984. I have a few questions for those experienced CBX750/CB750 DOHC owners. The guy I bought this bike from said it was running 10 years ago had a recent top end rebuild then...

Hello i’am new here and i life in Belgium. I bought myself a cb750c. The previous owner told my that the bike came from America where it had a speedometer in miles and he changed it into km. The certificate of comformity says that the bike is from 1981, its in Dutch and came from Aalst (Honda...

Does any one have a carb rebuild kit they would recommend. It's for my 1976 CB750-K.

Howdy ya'll I Purchased a 79' CB750K last spring and when I finally got it running n' driving I noticed that there was no fifth gear. Meaning, above 4th, it just didn't go anywhere. Did the research figured it was the shift drum stopper (maybe one of the pins fell out). I opened it up a few...

Hi all! I have a Honda CB750 F2 Boldor (1982) Factory carburetors, exhaust 4-2, velocity stack and jet kit. And there are problems :) (yes, I know how capricious these CV carburetors, especially in the absence of a factory air filter). The first time after engine assembly, carburetor...

I have 1974 CB750 Honda custom chopper, I picked up second hand. There was no wiring harness, it has bare minimum wiring. the rectifier, the voltage regulator and the starter solenoid is all located in a hand made control box. Its all ran thru toggle switch and a push button start with no key...

So I'm looking to do a few upgrades to the brakes on my F2C. The current rotors have seen better days (as you would expect for an 30+ year old chunk of metal) and rather than just opting for some OEM replacements that will also be used, i was wondering - does anyone have any...

Hello! New to this forum. I have a 1982 cb750 that I've picked up over the winter and done some work on, but my friend recently lost my only key :mad: I'm hoping to get some help/advice/walkthrough on installing a simple toggle switch to bypass the ignition switch so that I can still use my bike...

Hey everyone, Long time creeper on this page, picked up a ton of great information. I've scoured the interwebs of the future and couldn't find anything on this, so I'm hoping the motorcycle gods have bestowed this knowledge on one (or a few) of you. I'm building an '82 CB750F and I'm nearing...

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...

I really like the look of 4-1 exhaust, but am wondering if it will increase the sound significantly. I'd like to keep my bike on the quiet side. I especially like the 4-2-1 MAC Honda...

Hi folks, I was thinking of installing a sealed LED headlight instead of the stock one I've got. I thought of taking a Daymaker's one, or something like theirs. What do you think of it? Won't I get any kind of electrical failure if I attempt installing an LED unit?.... Thanks, Joe

Hello, I recently got my first CB750 (1981 Cb750F) and the head light is in rough shape. I want to go for a more aggressive(military style) look, but I am also new to building bikes! I would love some help figuring out how I can replace/modify the OEM headlight(and all those ridiculous wires in...

HI all, Can someone tell me the year of this front end. The previous owner said CB750, but didn't know the year. Thanks

Hey Everyone, I'm new here and was hoping I could get some opinions. I have a 79 CB with a 4 into 2 exhaust. I was thinking about cutting the mufflers in half and purchasing one of those after market baffles. The headers are perfect but the mufflers were spray painted black so I dont mind...

So kind of a complicated situation I've gotten myself into... but after doing some modifying of the frame geometry, I'm trying to calculate whether the Cognito Moto oil can will work on my bike... what I need is the dimensions between the mounting studs. So, distances between the four holes...

Hi there! Currently working on my first CB750 build (actually first motorcycle build ever), a 1983 CB750 Nighthawk (with a stock wiring harness from a 1982 CB750 Nighthawk Custom). I'm looking to upgrade the left side turn controls from stock to the K&S 12-0041B. I have the wiring diagram for...

Hello to all, new to this forum, recently got my hands on a '83 Nighthawk with a '82 DOHC engine in it, and since the bike isn't in the greatest condition I think it would be a perfect opportunity to customize it. First off I want to get rid of the teardrop looking tank for something a...
