restoration

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 Im new here and see there is some great info available . Happy to join the group. I have a 79 cb750 limited edition with a big dent on tank and would love to find a original limited edition tank in good shape. the bike has 6000 miles and want to keep as original as possible and fear a repaint...

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! My good friend and I are taking on the DOHC CB750 build. Our plan is a full rebuild, restoration, cafe to the nth degree of detail. We don't know a lot but are learning a ton as we go. If you would like to follow along and help us out our channel is below. We are much further than our...

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...

I'm at the end of my rope here, I have had the carbs off 5 times now, apart back together, apart, back together. I've cleaned them ultrasonically for about 5 hours... blew everything out put them back together and back on and the problem persists. My buddy keeps telling me it's dirt in the...

I currently have purchased a 1977 honda cb750 and im quite a rookie when it comes to building/restoring these types of machines. I just wondered whether someone would be able to tell me what this part is??? looks like its missing something?? Its located just beneath the battery housing unit and...

Hi guys, Just joined. I purchased an 82' nighthawk 750 that's been sitting for years and needs carburetor love. The bike arrives in two days but I thought I'd get a jump on things and get the service manual. I just purchased a manual from emanuals.com and it's supposed to cover the years...

So I recently thought I finished my CB750 project, until I started to hear this clicking sound when I accelerate it. Don`t know what`s causing it, so I wanted to ask you experts to see if anyone can help me identify the problem. It is a 1980 Cb750k. Here is a link from reddit where I ask for...

Hi there, I am working on restoring my first bike and had a quick question about seat compatibility. I have a 1979 CB750L, but the seat that came with is is torn, worn and base is rusted out. I just got a decent offer on a 1980 CB750C seat and I was wondering what the chances were of making this...

What the hell makes this piece so damn expensive and causes everyone to charge over $7.00 for shipping? Where or how can I make replacements for this tiny little piece? The ones currently installed are dry rotted and the suspension is bad so needs replacement.

New member signing on, just purchased an 81 CB750F with 12k original miles here in WA state. Runs ok but has been sitting for quite a while. Actually rode it today up the street and of course carburetion is an issue. Initially it looks like a float is stuck in #1 or #4(not sure how the carbs...

All, Let me introduce myself. I am Evan. I just bought a 1976 CB750 for $550. There are some problems. I believe the kid I bought it from didn't really know what he was doing when he was trying to figure out why it died on him..... things I found out today: No fuse box - Unless i'm looking in...

Hi, First time here, thought I would ask some experts' advice on a dilemma I have with my gorgeous '71 CB750. It's an all original bike, but has a 4-into-1 exhaust that I am looking to replace. I am looking to potentially sell the bike in future (I have a few of them), and wanted to know what...

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...

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...

I am getting set to ship my engine to have it restored and wanted to see if this group had any advice on shipping. Currently I have built a crate (using a pallet for a base) and that piece is complete. Wondered what thoughts are for securing the engine to the crate. I had been thinking about...

There is no engine tag on this bike. There is two numbers stamped on the engine and frame. I found a thread on here from 2012 where a moderator was able to identify a bike from the same type of numbers I have. If anyone can help with this please let me know. I have a CB750E-1098099.

New to the forum, my name is Dave Clark, from Columbus Ohio. I have a stock original condition 1976 CB750F, with 7,900-odd miles. Running and riding. I thought I was going to use the motor for a 70's 'Jammer' hardtail frame chopper project, but I think that would be a terrible thing to do...

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!

Hello all; new member to the forum. Wanted to log my build on my two CB750's that I picked up this past weekend, been wanting to do a CB build for the last couple of years and came across a deal on these two bikes that I just could not pass up! Ended up getting both bikes and almost four of...

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...

Howdy all, i want to purchase and restore a 1975 CB750. I'm not even sure how to begin. I am shopping for a hopefully running 1975 Honda CB750. I think what I'm looking for is a K model, not the cafe style. I'm not necessarily a natural mechanic but can still turn a wrench. I don't want a...

OK, today i cleaned the carbs on my 81 CB750 that's been sitting for over a decade. i also squirted oil on the cams before trying to get it running. i have not yet reinstalled the gas tank. i just added fuel to the float bowls with a hose and funnel then squired some starting fluid in...

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...

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...

Hi, absolutely new here, but not to CB750's or motorcycles. I am extremely lucky and i wont hide that fact. I had a '75 CB among other bikes back when i as young as i am old enough that they were common back then. 30+ years ago, but that is for the introduction thread. I found a 1976 Cb 750K...

hey new here and my dad gave me his old bike which is a 72 Honda 750 in a burnt dark orange color. BIKE HAS LITERALLY 1050 Original MILES. not a typo either. I know the bike has a different exhaust on it and il take some pics because I would like to figure out what type they are. I also have the...

Hey Everyone, I've Been working on my CB750 for a few months now and have found a pretty decent amount of help on the forums. Before the bike was barely running and wouldn't idle below 2000 rpm, Now its quite better but still a ways away from running well. I'm not a mechanic so don't be...

I am on the trail of a 1975 CB that has 3000 original miles on it and hasn’t been started in 41 years. I have not yet seen the bike but expect it to be neglected and not abused. It is the original owner and I believe the owner to be honest. Although I have ridden for 43 years, I am brand new...
