Hi Matthew - I use to work on motorcycles 50 years ago when I was young teenager. I recently purchased a 1975 Honda cb550 K1. Do you know if there is a big difference between the 750 and 550 engines?? I would like to purchase your video series and restore the 550, but want to make sure the 750 video series is similar to the 550. If you know I would appreciate your response.
Thanks,
John
@@johnfindley1249I have 550 videos here:

Thanks! I purchased the 550 videos
John
@@johnfindley1249 Thanks! Enjoy!
Question, do you have a version of this for the 900cc motor from the 81 model cb900c?
Hey all, I bought the 9-hour video and wanted to leave a review. I am just coming over the hill on my cb750 engine build and beginning to put it all back together, starting with the cases. I've reached out and looked for every resource I can, and this is by far the greatest thing I have ever run across. Matt takes time EXPLAINING what he is doing and why. He does something and then will put in the effort to undo his work, just to show it to you again from a different angle. This is now the gold standard of rebuild videos. Hackaweek has a great set of videos, and I would never speak a bad word about a great guy and fellow builder, but this video series is on a whole other level. The video quality, the lighting, I could go on. He has is all chaptered too, like a DVD box set, so finding where to go is super easy. Matt, you are the MAN for putting this out. If anyone is trying to rebuild a cb750, you need three things: A Clymer Manual, Mark Paris' (Hondaman) Book, and this video series. I was not paid to say this. I don't know Matthew and paid the full price. Cheers.
Jacob, thanks so much for the review and compliments. I'm glad it helped!
What a review, im buying.
I foolishly pick a cb750 as my first bike as I wanted to build my first bike. Got it for 350 usd so it was in terrible shape. I had almost given up but I will definitely be utilizing these videos! You have reinspired me.
Well how did it go?
How did you find one as a project bike? I am wanting to rebuild one myself and don’t even know where to begin
Matt, thank you for doing this. I’ve been wanting to restore my 750 engine for the longest time but was scared I’d mess things up. I bought your videos and watched every single minute of them all. I now have no second guesses or apprehension about starting this project. Thank you very much. Videos are too notch and I have already recommended them to multiple people.
Thanks for the compliments!
This is awesome! 25 years ago, someone gave me a '71 CB 750 chopper that had been sitting in his garage for 15 years. I got it running the day I hauled it home. At the time I was a single Dad with two teenage sons. I pushed the CB to the side to work with them on their bikes and cars and trucks. She's pretty rough now, because it spent a couple years outside the shop in the weather. It's a sweet old 70's style chopper that deserves to be back on the road. Your 9 hour video is just what I need to get motivated to working on it again.
Information is as important as any tool.
I just bought a 1976 CB750F Super Sport from a friend that will require significant TLC.
I maintain flight sims for the Army and can tell you that specific and accurate information is an absolute must.
The quality of these general videos is outstanding, so I bought the set (engine and carbs).
Even though this is my 10th motorcycle, it is the first Honda CB750 I’ve owned.
Best to have all the tools (videos are tools) before you start.
Thanks for taking the time and effort putting this together.
Wow what a great video! I’m 59 & owned 2 of these bikes in the early eighties. They are extremely high quality motorcycles. I would gladly pay for a step by step video guide to bring them back to life. A no brainer!
I used to have a couple of 750’s in the 80’s and is thinking about getting one again. If so I’m definitely going to buy the DVD.
Greetings from Denmark 🇩🇰
killer work dude. engine looks so good.
your videos are perfect, i really appreciate you taking the time to make these.
Brilliant work, I have a 78 k7, once I've decided what I'm doing with it I'll look at purchasing the 9 hour set. Thanks for sharing your work.
Love the videos !!! Keep em coming
Thanks for the screw/bolt depth tip!
Just to think... these devices run on fuel from the bottom of the ocean. Engines will always be fascinating.What a fun experience and such a magical production this is!
Such a great motor. I had a couple of those CBs. Long time ago.
Excellent work!!! Excellent videos!!
Love it, this guy know what hes saying and deserves the praise
Great video. I appreciate the thoroughness even in this limited version and look forward to buying and watching the complete set, which is well worth the price.
Thanks Mac!
These kind of videos should not be free i am looking to buy cb 750 K1 and this video package will be the first thing i buy for it😂
Great Job !! Your a very skilled mechanic. Greets from The Netherlands.
you are a very special man mister!
Hi Mathew thanks for the videos, after watching them I decided to buy the full 9 hour rebuild. I had a sneak peek and it looks amazing, exactly what im looking for, Will keep you posted, not looking to starting on my 750 till next year spring time, in the meantime I will start watching the 9 hour vid. Many thanks.
Alan from Scotland UK.
Thanks for the feedback! Keep me posted on progress.
Amazing job
I totally get it ... I was going to film the rebuild of my 77 F2 ... when I realized how difficult it was to keep all my cameras running, with good angles, good lighting and keeping everything clean. Ha, I scrapped the idea real quick. I only had Saturdays to work on it, and it's taken me about a year. I had to swap out the bottom half of the engine casing because the previous owner had a chain smack that split it. So I had to take apart two of these identical engines. So much work. Thanks for sharing!!!
Thanks for understanding!
Definitely buying this as soon as I'm ready to vapor blast the parts. If this is as good as your vapor blast cabinet plans, I'll be extremely happy! Nice one.
Same video quality :)
Exactly what I need for my CB-750 build....now if you'll do one for a Virago 750 I'll be totally set!
Thank YOU!
'Tis a thing of beauty :)
Looks beautiful
Thank you!
Respect ur work... I am from India
Outstanding job! About to take my 1982 cb750k engine apart for powder coating. Crossing my fingers I do it half as good as you!
Good luck!
You absolutely should be charging for a nine hour video, good on you keep up the good work 👍
Máster of universe jaja saludos desde Argentina. Un fan suyo.
Amazing job. Well done.
Hard to believe anybody would think a 9 hour video should be free ...
No way would you want to give it away for nothing, they don't give away haynes or chiltons manuals and a video is twice as good imo. Its a TON of work making a repair/rebuild video!
Great vid. I think you should charge for the vid!! You put so much time into it!! Thanks
Great video.
I'm looking into buying a cheaper 750 and if I do I'll most definitely buy the full version.
Thank you!
Awesome!
Man, this is so awesome. Do you think you could please do one with the DOHC fours from the late 70’s, early 80’s? These bikes are now also wildly popular and I know that a ton of us, myself included, would benefit greatly from. Thanks for having such an awesome channel and making all of this look so easy!
I'll add it to the list.
Around 1984 I changed the primary drive chain because is was clunky on my ex police 750 four (a big heavy job)only to find that the original one was perfectly ok and just needed the tick over increasing slightly!
Man, you don't get paid enough...great vid
LOL
great rebuild...amazing ability and technological skill...and then uses a screwdriver to insert the piston rings...
Yeah so what?
Thx
Hi, great job, one question did you machine any part or crankshaft and piston are in std size, valves?
Unbelievable... fantastic work. Any chance of doing an '81 DOHC tear down and rebuild video?
Maybe someday.
Curious approximately how wide you think that engine is? Thinking about doing an electric conversion on a similar bike cuz the engine compartment seems huge
Mathew do you have a video for the carburettor bank for this same engine, 1978 cb750 k7 ?
I purchased the 9 hour video which is brilliant, I now need the carbs video if you have one.
Thanks.
Yes I do: matthewmcrepair.gumroad.com/l/cb750carbs
Hello
I came across your video while doing a search for vintage Honda motorcycle engine rebuild. I don't have a cb750 , but I would surely buy it if I did. I have a 1964 Honda benly( baby dream) what advice would you give if I wanted to rebuild the engine. Dam I wish I could find a video for that
Any possible way you couple make a video about taking apart and reassembling the 78`s carbs I'm gonna buy your video but the carb 1 would be a gem
Same here, planning on buying the 9 hour vid, carb vid would also be super.
@@balmeros272 ur right... 😂
@@heidhouarbi I bought Mathews full video for cb750 teardown, Jeez I totally recommend it, Ive watched the entire video and it is absolutely fantastic and worth every penny, hopefully he will do carb video for K7, I will be 1st in queue to buy it as well.
A lot of time and effort was obviously put into these tutorials, I swaer by Mathews work.
Great video where did you buy all the screws and bolts. Do you have a web link
Search eBay for a kit
Great Videos ! I’ve purchased the full video as it’s well worth the money. You’re like a colour Haynes manual. I’m planning a CB build soon but I’m wondering is there a big difference in the engines after 1978 ?
I think some models have the DOHC, there's a difference. I am now wondering if it's still the same when it comes to the bottom end rebuild
The sound to start.Go 750 k.
Nice work, something therapeutic about watching someone strip a bike........ Should really be doing my own, instead of sitting here 😂
Absolut super cool! What do you suggest this would cost in a shop to be done?
Probably around 4k. Call cycle exchange and ask for a ballpark.
First of all, many greetings from the Rhine-Main area in Germany. What have you done? The video is top notch... truly incredible. Thank you for this helpful, targeted and practice-oriented performance aid.
Today I just have one final question: Is there a table with all the relevant torque specifications available? If not, I would be very happy about the information "Where can I find the torque values in the service manual".
Thanx in advance for a quick reply. Greetings from Germany - Matthias
I call out the torque values as I work through the video. They are also listed in the service manual.
Ah dangit, I was looking for the DOHC video and got excited when you mentioned the full rebuild video. I would happily buy it if it existed after reading the comments. Sigh... 🤕
If it exists please LMK.
I don't have a video on that model yet.
Any chance you will do a 750 DOHC? I just bought an 1982 CB 750 SC. Thanks.
Hi Matt may I ask please how much toatal cost of rebuild as a guide please. Not counting man hours of course. Thankyou
Matthew, does only the top end need to go to the machine shop? Also, it seems that one needs to do the bottom first for a full rebuild? I got me the cyclex git kit#1. I bought your full video but haven't gone far on the bottom end disassembly. Just finished the top end disassembly. Thanks
Hard Q to answer. Has this engine run before or what? What is the purpose of rebuild? Something broke?
MatthewMCRepair it was working before but gradually degraded over time until it didn't run anymore and took it to a Local repair shop. They did a compression test and it had low compression.
They wanted a lot of money for a top end rebuild. So i thought I'd do it myself.
need a video for an xs 1100
Do you think you could tackle this as a total beginner? I’ve always wanted to rebuild an engine, and this seems like a fairly approachable platform. Think I’ll get in over my head?
It can't be any easier with this video. Go for it! Tons of first timers had success with my rebuild videos.
What format is the video?
Hi I just bought 1975 cb750f I was wondering if you would be interesting doing complete rebuild like this for someone please let me know. thank you
Can I get this type of repair video for the 1979-82 Honda CB750F Honda
Would the content of both vids work on a ‘75 550?

Hey I have a Suzuki 250 that when you feather the throttle it goes dead but after you let it warm up it runs fine I put a new carburetor on it any ideas
Does it get better with choke partially on??
Do you have a video for a 81 cb 650?
No sorry
Is there a part 2 on what you did with it?
ruclips.net/video/VKp8s1wv8vs/видео.html
Hi I'd.like to know where can I get a guide chains and tensioner for my engine I have a cb650c 1980
ruclips.net/video/eqe59cINk7A/видео.html Find the PN"s. If not available OEM, then search ebay.
Would you ever consider the most common engine the VLX 600 complete rebuild?? I would be first in line. Thanks👍
theres way too much time invested to give this info for free. Shops don't do it, neither should builders/fabricators. Thank you for posting....
2 questions for you:
How much was spent for parts and external work on the build? (Not including your time)
What was the case finished with? Soda blast and polish?
Watch this ruclips.net/video/SCqa_7H7hKs/видео.html & ruclips.net/video/pJiNfUYFAXw/видео.html
What u think how close is 1997 cb 750 gearbox for this engine?
A lot of changes happened in 20 yrs. However the techniques and principals in video are the same.
@@HTMR just was wondering. Normally I forget stuff when I open engine and than waste time because need to open it again because some gear or fork is wrong side in
I have Honda 1981 Blodor CB 750 RC 04 but electric wires all is burned i dont know why and i cant to find new wires or to make new by myself 🥺
Sincere question: As I never begin a Motorcycle Rebuild and Precision Restoration to Factory Specs without Buying the Manufacturer's Mechanic's Repair Manual covering the Year, Make, and Model Motorcycle I am doing a complete Motorcycle Rebuild and Restoration.
My question is this: With the purchase of both of your Upper and Lower engine rebuild videos of the Honda CB750 Engine -- with the manuals you include -- will I still need to go to a Honda Motorcycle Dealer to buy the Manufacturer's Mechanic's Repair Manual for a 1976 Honda CB750 ???
Other than this -- is there a time limit on your support with this purchase ???
I ask because although I have accumulated decades of all the appropriate multiple different skills with which I have brought motorcycles back to life -- I do not currently yet have my new Machine Shop / Bike Shop Built so am not able to begin the Rebuild/Restoration until I have the shop in which I can get back that part of my life. I have a 1976 Honda CB750 that whilst it is seriously in need of my experience and skills is most definitely well within my proverbial pay scale level of knowledge and skills. Yet this is also the first time I have had an opportunity to purchase videos of an entire upper and lower engine rebuild and restoration.
Whilst I do have the knowledge -- as well as the experience and skills -- with which to do the machining -- I place an exceptional value on the things I may learn from your videos of this engine rebuild.
NOTE: Just a bit about my history as to why I dedicated myself to far more skills than also having dedicated myself to becoming a precision machinist and a precision motorcycle mechanic.
Before I had become a bike mechanic -- my absolute most severe bike crash: While I was riding a 3-Speed Bicycle -- the Front Brakes DEAD STOPPED the Front Wheel. I was thrown airborne over the handlebars and Head First Directly Into The Road where I suffered -- Brain -- Cervical Neck -- and -- Spinal -- Injuries.
It was after that high side bike crash that I dedicated myself to becoming a precision motorcycle mechanic. During that process I also became highly skilled in multiple other related skills. All of which has enabled me to Rebuild and Restore Motorcycles To Factory Specs before adding Crash Bars and changing out the factory handlebars to custom tune the riding position.
I was the recipient of someone who attempted to tell me I should not ride motorcycles because of how dangerous they ere. So -- of course I most definitely refused to stop riding motorcycles. I mean -- it is like -- why would I ever stop doing something I enjoyed as much as riding motorcycles. Where would there ever be any enjoyment of life in doing that ???
Meanwhile -- should I get to live long enough I would purely love designing and building my next motorcycle from the rubber side on up.
The service manual provided is sufficient. I offer email support. Sorry to hear about your accident.
Hello, as an European I wondered if the I can buy the guide and still use it with good accuracy ? I am technically educated (elektromechanics) and do every basic maintenance on my bikes. Let me know looks like a golden nugget you don't find that often online!
Yes you can buy the video. It will be very helpful.
Is this 9 hour video detailed and does it go over everything you need to know to rebuild a cb750 engine correctly
Yes sir
🔴🚨‼️Tengo una Honda súper sport cb750f 1977 , ocupo de un mecanico que haga en el tiempo justo que ocupe la moto ese mismo trabajo! Hay alguno en la CDMX ??? 📍🚨
I would like to buy your motor rebuild video for UK format.
Not sure what you mean UK format? The video is streaming only by logging into a site that hosts the video.
Hello Matthew...i want to rebuild my cb650.. Can you help me suply for some engine part ? Thanks before Mr Matthew
I do not sell parts. What are you looking for?
@@HTMR i'm looking for camchain for cb650 sohc..can you give me for info?
How can I contact you for questions regarding your cb750 build
www.howtomotorcyclerepair.com/contact/
Hay whatts your hourly rate
I need my k5 done.
I do take on service work sorry.
Can you do a DOHC 1980 CB 750C rebuild? If you have a video for sale for that i'm planning to buy it
I'll add it to my request list.
MatthewMCRepair whoa thank you!
you didn't do your own valve job? not that difficult. for what it costs to get it done, you can get a set of Neway valve seat cutters for a lot less, its actually fun.
Where are you located? What would you charge for doing my CB750?
Chicago. Not accepting service work at this time.
How do I recover the videos that I purchased?
Email me I can help.
Have any of these guys heard of Kroil?
Haha I was using that throughout the video.
it's a #3 screwdriver
Is this still available
Yes: howtomotorcyclerepair.com/cb750-rebuild-videos
How much do you charge for a rebuild like this one?
I am not accepting service work. Contact these guys: www.cyclexchange.net/
Is the 1982 engine completely different ?
Yes
its totally fair to charge for the video....
Thanks for understanding.
Oh no, don't use an impact driver on alloy threads, even if the tips are JIS. You can remove these using a friction compound (Screwgrab or grinding paste) and smooth application of torque without stressing the threads.
Been using impact drivers on alloy threads for over 40 years, same as in this video, never had any issues at all.
@@balmeros272 Me too, since 1978 (44 years) on aircraft and I've experienced countless occasions where the non specialists may get away with it most often, but on those few times they've been unsuccessful, well I can't describe the damage they've done to the aircraft.
The argument that something has been done for over 40 years without any issues is no justification to continue. Most people live to much longer than 40 years without a heart attack but that first time is a kicker.
@@techo61 So your saying "non specialists" have been unsuccessful while working on aircrafts, by non specialists im assuming you mean untrained staff working on aircrafts, very odd, hmmm ! Similarly 44 years is neither justification or indeed verification that youve been correct all those years.
In any case im here to follow the post and the guys procedures work for me, he has went to the trouble of providing a great video which is clearly very helpful to those of us actuslly working on a cb750.
Enjoy..
Can I say people are out of their minds
I’m about to undertake this project and if I do I’d gladly pay the 50 bucks. However I agree Ken and Prez at CX are the best and I may just crate mine up and send it out to them. Their motor rebuild vids are bike porn 🍌
Hi ! Can you do that for me ? My engine is free
Damn, can no longer find many rebuild videos without their creators trying to heavily monetize them.
It's a 9 hour long video and worth every penny. A shop will charge you thousands.
@@HTMR Recently met someone who had both the manuels and the knowhow to support my build - all for free. Hopefully once you get your money's worth out of your content you could throw them videos out for the less fortunate.
Anybody wanting something for free are not serious about rebuilding the engine….
I would purchase the video without hesitation if I had to rebuild a similar engine.
Thank you!
$50 for video full rebuild? thats too cheap
Is that right!
YOU COULD HAVE BEEN EMPLOYED BY RC ENGINEERING BORN TO LATE.
Title rebuild. 11 minutes of removing valve cover fasteners smh.
No thanks🤣
You should just skip the monotonous stuff like breaking all the vc screws loose and taking them out, its not necessary.
Troy Buhay actually that was an interesting part. Shows the level of care and detail to disassemble intact.
I’ve lost count of the amount of times I’ve seen botch job cowboys who strip the head and then drill and remove the screw - and if they bugger that up too then they need to helicoil the threads.
Nope don't skip a thing! There's a lot of great tips in the details. Wouldn't want you to miss em.
