build

Just purchased a 1978 cb750. The engine has what appears to be a cracked upper and lower case. I am tearing the bike down to the frame, and starting the restoration process from there. My current intention is to cafe the bike. Feel free to voice feedback/advice/opinion.

Hi guys I restore and rebuild my Honda Cb 750 Custom from 1981 r. This is old bike, maby not so old but older than me and breakes are preety good... but it could be better. What kind of break calipers and disks I can put on original forks? Any sugestions?

Hey all, I've been getting really annoyed with how low the bike sits when i put it on the side kick stand and was wondering if any of you have had experience with trying other kick stands so it stands at a higher, more comfortable position. I've read that the 1981 cb900f kick stand is directly...

Picked up two CB750F's as I stated in my first post in the Lounge section, and the plan is to get one running and sell it to try and recoup some of the cost of buying them. The other will be a restomod into a muscle style bike with modern running gear like the picture below. This is how...

Hello everybody. My father-in-law and i are selling pretty much all of our Honda 750 parts bikes and other miscellaneous Honda bike parts. I wanted to post this here first to give true Honda 750 enthusiasts a crack at all of it first; before i post it locally. We have pink slips for most of the...

Im making a wiring harness. This might be a dumb question but everywhere I read they say the wire from the coils go to the "points" and to the battery. What are the "points"

So I'm currently in the process of putting my engine back together after completely resealing it and I've hit a wall. I'm just about ready to put my cams back in but while reading the manual I cam across it telling me this . What exactly is the "1,4T" mark/position? Does this mean that cylinders...

Hey everyone I have made a few posts here and there but I haven't properly introduced myself. I live in the Austin, TX area and recently acquired a 1982 CB750sc Nighthawk for $400. It was in pretty rough shape, but I am stubborn and determined to clean her up and put her back into service...

All spring on my rough idling, popping, grumbling 1977 CB750 I have (in this order): 1. Rebuilt the carbs (they badly needed it--new boots and top dust covers) -followed the Hack A Week video - thanks Dino 2. Tested the float level 3. Synchronized the carbs 4. Cut plug wires back...

I recently purchased a 70's style chopper that I intend to build, it is in rough shape. Good AMEN frame and springer front end with a stuck 750 in it. I am looking for a donor bike with a title to transfer but am at a loss what to look for. Is there a major difference in earlier and later cb...

Hey all, This thread is going to show my project from start to finish. Bought a 1976 CB750 k6 for 400$. Kinda a weird deal but if it goes bad i can part it out and make most back. The guy i bought it from never touched it, just bought it from someone, put it in his garage for a year, then...

Hello Everyone! Time to start a new project. I scored this $200 beauty a few days ago and the passion is starting to burn deep!! The plan is to build a rat/post apocalypse, Mad Max clone all purpose custom bike! I will start by accessing what works, and what's broken. So far I need a few...

Working on my first project and first CB750 got a couple questions about what I got here. I removed the luggage/saddle bag rack as well as the vetter fairings and with out the fairings I have no headlight does anybody know if anything was done to the wiring when they put thes vetter fairings on...

Hey everyone! I just got a set of Accel coils for my '81 CB750 Custom. A few questions... --Is it OK to just swap the old coils with the new ones? Is there any other componeny of the electrical system I'll need to tinker with? --The instructions recommend changing the (main?) jet in the...

Good morning guys! I am not a stranger to forums but this is my first post on CB750.com. I'm a big Volvo car guy and a mechanical engineer by profession, so in slowing down some of my car interests I decided to look for a bike as it's not something I'm familiar with and I needed something to...

First bike, first post. Let’s do this. But let me start by saying, sorry if I get a bit long-winded. As Mark Twain once said, “I would’ve written a shorter letter if I had more time.” Bought this bike about 10 months ago and have spent that time stopping leaks, stripping off the bullshit, pod...

I am getting ready to paint my 1971 CB750 engine cylinder head and cylinders with the black wrinkle paint. Any suggestions on brand and applications. I had the wrinkle paint on my 1973 back in the 70's and I really loved the look. Anybody with successful experience with wrinkle paints? I have...

I recently bought a 78 CB750, for which I am planning a modest cafe build. Nothing too radical, mostly low budget, with the focus on being a comfortable rider with a bit of style! For starters as of now the bike runs but not well, choke must be on all the time, but I will be addressing that...

Hello fellow CB750 owners! My name is Simon, I'm 23, Austrian and just traded a ragged out Porsche 924 for a '72 CB750 which was a former drag bike!! I restore Mercedes/Porsche from 50s through 70s for a living, that's what brought me from Austria to the United States. I got the bike, basically...

Anyone know if a rear fender from 80-82 650/650C/900C (part # 80100-460-000) or 80-82 750C (part# 80100-425-730) will fit an 82 750K model? I know the 80-82 650C/750C/900C front fender fits. I want to keep the original rear fender, lose the "lip" around edge of the fender and chop/shorten a...

I got this 1980 CB750C a year or so ago and have been slowly trying to turn it into something with a little more style. I am going for a relaxed cafe racer look. Put K and N pod filters on it as well as a Vance and Hines exhaust I got a good deal on, and had the carbs rebuilt and re-jetted by an...

I would like to put pods on my bike. I currently have stock main jets on the carbs (115) what size main jet should I get? I also have (38) slow jet size. And, should I get a shim for the slide needle? If yes, than what size shim? Thanks.

Hello everyone ! I'm new to the forum, and new to the CB750. My dad owned a few CB's of varying size when I was a kid, and I've always wanted to build one. I was looking for an SOHC, but came across a barn-find dohc deal that I couldn't say no to. Got the bike complete but non running, I...

Hi, new member here, I have a 1980 CB750C and I wanted to know if I could fit a CB750K tank on it. I like the look of the K tank better than the C tank. What will I have to change to fit the K tank on my bike if its possible? I think the mounting points for the C and K tanks are different, but...

Just a quick introduction to say hi to all you good folks, as I have just bought a 1981 Honda CB750 Custom as my first bike in over 25 years, having been taken with the idea of making a Café Racer for some reason...

Hey all, just started this build a couple months ago. Any help, thoughts or opinions will be appreciated.
