This is my first post so please let me know of any etiquette infractions. I bought my first Honda, a 1978 CB750F, yesterday. It's in pretty good shape all things considered but I thought I would start with a muffler to keep the neighbors at bay. I don't necessarily need OEM but I would like to...

I’m hoping with some experience, that some one can lead me in the right direction. I’ve got a 71 CB 750 K1 with new Keihin carbs and new Dynatek Ignition. My question is do I have to change my spark plugs to a larger gap being high energy ignition? When I’m riding it, the top end is scary good...

Hi guys, I'm trying to decide upon a battery for my CB750 DOHC project. The following is a comparison of the options I've come up with. I know the Shorai is a "safe bet" - I see loads of people using these. Just wondering what your thoughts were on the LTM14BL or YTX14AH-FP units. They're...

Getting ready to put the engine of an 82 SC back together and I want to bring the head surface to a good finish. There is for sure some surface rust from the original gasket left over onto the aluminum. what would be the best way to get this cleaned up nice? I plan on using gaskets from here...

Hey Guys, New to the 750 build but learning a lot. To keep things short I have a 1982 CB750SC. It had 36,000 miles on it and never saw it run before tearing it down. Compression in cylinder 1,2,3,4 = 75,75,80,60. Adding a small amount of oil raised each by about 5psi. Water testing the heads...

Hi and greetings from snowy Finland! I'm totally new with bike electronics, so I would appreciate very much, if someone with knowledge could comment my wiring schema. Biggest unsure is with how to connect reg/rec, spark units and coils with M-unit. I would like to have it so, that electronics...

After searching for a while i finally found these on ebay. Just got them at my house in india. Just wanted to show everyone and understand if they were a good buy. Also bought forged connecting rods. I believe that i would have to cut the washer at the bottom to clear the cylinder. Can i use...

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!

Intro... Picked this up just before Thanksgiving weekend. 78 CB750K. 14k miles. Been sitting in, and next to a barn for 25 years, or more. Goal is to get it back on the road as a reliable rider, and enjoy as an original survivor. Maybe put some flat bars, and give it a more muscle bike look...

Hey Everyone, Thought I'd post the story of my 1977 CB750F. All my moto-buddies have newer bikes, and all of my gearhead buddies are into 4-wheeled vehicles, so I'm hoping this forum will be a nice way to keep track of what I've done and maybe get some emotional support! I bought my bike...

Hey guys, figured I would share CB750 build with the forum. It has been an interesting one.. I'm typicaly a little more of a car guy but I was in Miami one day, saw a cafe racer and fell in love. I looked at it sitting there in my girlfriend's grandmother's parking garage; and knew I had to have...

so I'm in the process of test riding my 1981 cb750k every other day because I've just recently completed a rebuild on it and have run into a bit of a running issue and I wanted to run it by some of you. So to break down my current set up, I have 4-1 aftermarket MAC exhaust with a baffle in it...

Hey Guys! I'm new to the forum and would like some advice from some of you who are much smarter than I am. I'm currently in the middle of doing a full engine rebuild ('75 SS). Most of the websites seem to have parts for the K engines but seem to have hardly anything for the F engines. I...

Seeing as I've made a few posts now, I felt a quick hello was in order! I'm Andy, based in the UK but I've travelled and lived all over the place. Bought an 82 CB750 as my first bike. What I thought would be a couple of quick weekends in the shed getting it sorted for the summer is slowly...

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...

hi guys first post here. so my friend has a 1979 canadian police model which was used by the local police here. we bought this model and are restoring it the police models were K type and we really like the look of the F type supersport and are going ahead to source body parts to make the...

Going to brat/cafe this beautiful K4 - I have the carbs and air box - The stock speedo/tach is in excellent condition so I plan to keep it - Leaning toward clubman handlebars (need suggestions on grips, etc.) - Am I able to use clip ons and keep the stock speedo/tach? (if so, need suggestions)...

Hello everyone! Finally I have decided to show the evolution of my project. It's taking shape these last days, and I'm happy with how it's going. First of all, I introduce myself: I am spanish and an industrial designer. It's my first "big" bike and my first project. And I always had the...

Hi All, So I picked my bike up on Friday and today got to start doing something with it.... It started as this: Then moved on a bit to this: Then: And finished at this stage before the snow started: Anyone got any tips on where to cut the rear frame to add the hoop? Speak soon :D Odin

Hey guys, I am trying to do pods on my 82 nighthawk. Anyone have any tips or videos on how to mount the carbs without the airbox? Thank you!

Just thought I'd share my success. I'm building a bike from basket cases. The engine, carbs, everything completely rebuilt. She fired right up. I have some tuning to do and a lot more work to finish her off, but I'm way ahead of schedule for being able to ride it next summer.

Does anybody know the sequence of assembly of a bike starting with just the frame (chassis) to pressing the start button? All major components assembled. Thanks.

Two years ago I got this old CB from a welder I worked with on a building site. It had been sitting for 12 years since the engine had broke down, So I had it for free. I immediately tore it down into pieces and after that I´ve been working on the engine when theres time for it. I´m married and...

Hi, My '81 CB750 super sport has broken right handle bar controls. aside form the original what else can I use to replace them. If I plan to keep a clean handle bar look what do you use to replace the switches?

Hi Everyone, So this past summer I picked up a mostly complete 79 cb750 to build over the winter. This weekend I got to wheeling the bike into the shop and starting on it. So the plan is to build a pretty simple brat style bike with an emphasis on minimalism and reliability. So the plan will...

So my awesome uncle gave this to me. His son, my cousin, had it for a while. The plate tags on it now are from 2010. I got a set of keys made for it and hooked up one of my other bikes to it. The motor turned over but didn't start. I've ordered a battery for it. Here are some pictures. This is...

Hello All, New member here, just got myself a '80 CB750K for a winter project, goal is to make it my daily next year. (just moved to Wisconsin and it seems like EVERYBODY rides up here) My other ride is a 78 Yamaha XS400, it did great around town for college, but it is pretty taxed on the...

Hi, I just bought a 1980 750k and drove it home. I thought it was running a little off and attributed it to the carbs not being synced or jetted correctly. I went home and looked at the spark plugs and decided to take the valve cover off. I am just curious to know if oil build up like this is...
