I'm an old school motorcycle dude started riding in the 70s. As much as I love my new bikes I really dislike and struggle with all the technology crammed up my ass. I don't want traction control, abs, riding modes that each have their own riding modes! Wtf? I just want to ride. I miss my old bikes with carbs and "manual" controls. I love your videos. To see the younger generation embrace the early machines and keep em going, in original condition gives hope for our planet.
I purchased this exact same bike, orange 1972 CB750 K2 brand new in 1972 (just graduated from high school) for $1820 out the door. It was one of the best bikes I’ve ever owned. Open the throttle and it screamed. But just cruise around and it purred. Can’t ever remember having a problem with it. Wonderful bike.
My 1st bike was a 1976 750. With my father-in-law and his 73 750 and his son on a 500 we took our first cross country from Topeka to Roesburg Oregon. I still see the 1st time seeing the Rockies later Yellowstone then the Pacific. What a great trip for this flatlander and what a great bike!
I have my Dad's Gold 71' Honda 750 four I will be trying to get running. came across your videos and I have been glued to them to learn all I can. Thank you! for doing these videos.
I ran a cb400f1 for 18000 miles bought from new in 1976-issues were sticking front disc calliper hinge and water ingress to coils- location was prone to attracting road spray. The calliper hinge was alloy and the pin it pivoted on was steel hence prone to seizing-addressed through stripping and copper grease. Bear in mind it was my daily ride in darkest wettest South Wales. One strange issue as failure of the frame tube due to corrosion at the prop stand bracket. It was followed by a cb550f2. I covered 62000 miles on that orange beauty over 4 years. I fitted electronic ignition and a Peter Furlong full enclosure chain case-ugly but effective in extending the life of oil sintered Izumi chains. A Cibie bright headlight conversion also improved matters. The nylon swing arm bushes were replaced with bronze items. A pig of a job-I think the 400 had grease nipples as does my current ‘03 Thunderbird. I always fancied a Difazio box section swing arm but they were super expensive. Keep an eye on the mudguards. My rears rotted through in no time-that old Welsh weather again. Rear brake cam was also prone to seizing-due again to steel to alloy interface-there’s a felt washer which you should keep oiled to keep the h2o out
Well thank you much! I always try to share everything. Definitely check out my 1975 barn find cb750 revival. I have a ton of videos on it as I brought it back to life and now enjoy it
It was amazing to see your video on the Honda I was very impressed on your ability to fix those old classic bikes My first bike was a Honda 750 I bought it when I was 15 years old for $800.00 bucks I had the best time of my life on that bike Now I am riding the ZX14 Ninja and the Kawasaki Concourse 1400 abs still love the speed. Your like Picasso only with bike.
I owned one of these bikes - with the four separate exhaust pipes - which makes it a CB750-K2. I bought it in 1976 from a dealer, so first registered in 1973? We (me + girlfriend) rode it round France - very steady as a Tourer.
Thinking about getting a classic bike from my era growing up & wasn't the best mechanic ( Even with point's electrics) but even I can kind of follow what you're doing. Which is big praise if saw me in a garage ( Fighting with spanners & screwdrivers 😁). Made me a step closer to buying my dream ( Mid life crisis) bike & won't be so freaked out by D. I. Y mechanics with people like you out there. Takes me back with mates...... " Did ya check the fuel, what sort of spark ya got " Thanks my friend 👍😁
A great demo on what to check & how to do it. No great surprise with the degradation of the plugs leads after almost 50 years. The green fuel was different, lol.
Excuse me while I binge-watch your channel! Love the video-style editing. Simple and fun are good! Works and flows well. Getting nervous sweats because I want to ride my 79' so bad. Getting paint-matched bags back from the painter here soon and a top-end rebuild over the winter! I can finally tune the carbs in because the gaskets are leaking so bad lol.
I've just found this channel and doing exactly the same myself. Guilty pleasure of watching someone else work for a change. I should be in my shop as I have 3 Norton engines and 3 gearboxes requiring my attention 😱😁
I had my carbs sonically cleaned, did a basic balance myself and fitted electronic ignition. Made a heck of a difference. Only bad bit it got rid of the popping in one of the exhausts when throttling off. They never did that back in the day but it was sort of quaint for a 50 year old bike.
Nice to see someone having a play with these old girls. I think you should sweet talk the owner to go for electronic ignition. I did just that on my Z1s and never looked back. Keep up the good work.
Thanks Terri, I just hope he is able to put any miles on it this season. He is wise with life experience so throwing that leg over the seat is not as easy as it once was.
@@BrickHouseBuilds Tell me all about it. I'm in my 60s, but I still love taking 1 of the old girls out. To watch people's faces, it's like having a model on your arm.
Fantastic video BJ! I'm in the process of resurrecting a 1975 CB 125. 2000 original miles so this is great info. Right now no spark so...Thanks again, keep 'em coming.
Excellent diagnosis, great tips too. I had plastic jet in my Yamaha SR 500 single and it vibrated out but never stopped running until it drained the tank of fuel lol. Get shot of them if possible. And yes I did fit the jet in the first place , never again. Cheers Richie.
I had this exact year CB750K back in high school in the 1980s. I swapped in a Dyna S ignition in lieu of points and condensers, and accel coils and wires. They had yellow wires with orange boots, therefore, they must be better. Kidding aside, the electronic ignition conversion was the single best improvement, no more pitting points, checking dwell angles, and wondering what the difference between a good and bad condenser is. It also had Weisco 811 pistons, a Kerker 4 into 1, re-jetted the stock carbs (although 29 mm Smoothbores were the goto swap back in the day), Barnett clutch, re-valved damping rods and progressive springs up front, tapered bearings in the front stem, a trimmed front fender. I also ran all the control wires through the inside of a low rise GP handlebar. Had Orient Express perform the machining work for a 5 angle valve job ( or was that 3 angle?). Super reliable and durable. Nice work, thanks for the happy memories.
I'm typically all for upgrading and updating but this wasn't needed here. Just keeping it simple. The bike is local to me so if the owner starts seeing issues this season it can be addressed then
@@BrickHouseBuilds I hear you, it is not your project bike. Do what the customer asks. I would be scuffing the back of those side covers, mixing up some Part A Part B epoxy reinforced with some fiberglass mesh. That will stop those cracks and make it stronger than stock. Ideally you would also do some work on the front face, but that means a respray.
Great video BJ! I've been chasing ignition issues on my frankenstein XS400 for a couple weeks, finally narrowed it down to bad spark plug cables... then watched this video after. Would have saved a lot of time if I watched this first 😅 Your channel helps keeps my project motivation up! 💪
Well thank you and I'm glad it...could...have helped lol. I've learned all of this stuff by trial and error so I feel ya. I just want to pass on the stuff I learn to the next person.
great video! might be worth mentioning that all the old Japanese bikes have stripped screws because they are JIS (Japanese industrial standard) which is not the same as American philips screwdrivers. *EDIT. i wrote my comment before you mentioned JIS screwdrivers... :)
Great video! Thorough testing and a laundry list of things to fix. With the mangled timing advance screw I thought you missed an opportunity to talk about JIS, but there it is. And while I understand that this a service to get it running right one of the additional things I'd want to do is to fix those side covers with some plastic welding before they split in two (four?) and disappear.
Thank ya! I'm sure you are watching part two now and in that I address the cracked covers with some epoxy to at least help it last a bit longer. The right side cover was bound to break and fall off.
I really like your channel so much it bring bring good old memory of mine riding time in the mid of the 70. This bulb matter bring back.mine time. You CBX 1047 bring back those good old day which I own one. Now sure it history for me. I just love you channel very precise you give this old horse a good new life. I still live in the old world 🌎 ha ha.
@@BrickHouseBuilds Not like old bike. New generation bike may be better. But with all those groove electronics riding aids. To me is not too much of a fun at all. I kind of old school old bike you can get it fit. If you are out for a touring. The new one if they don't start cranking the engine you at surrender. You can look at the sky n pray. Old school you still got a chance to get it fit.
@@ansonlow7764 I agree but do like both. The older bikes take more care as they must be treated differently but are very rewarding. New bikes sure are comfy and smooth though!
Lembro bem das Hondas com essa tecnologia four. Tive oficina e mexi em algumas mas nunca desmontei o motor, apenas nas Suzuki de motor 2T. Essas eram as motos mais cobiçadas da minha época. Parabéns pelo vídeo.
its amazing how much of a headache these bikes must have been for mechanics.... im amazed at all cb videos ive seen someone has always tried to repair different or find some janky repair etc
I took your advice and am watching these videos. Im really getting a lot of great advice on what to look for. Quick question I noticed I have oil in one of my reflectors on my forks. I’m figuring it’s a busted seal, but it still has me freaked out a little. Dude are you In Missouri or Vermont? I’m in Oklahoma bro. Anyways you rock!! See ya.
Enjoying the video! Wee question - when setting the "fire" timing could you set align the fire mark on the crankcase then rotate the timing board until it lights rather than trial and error it?
Thanks for sharing your knowledge really enjoyed video. I read that one of initial checks on machine should include inspection of valves (x8). Would you agree or is it unnecessary?
I owned the CB750 and did all my own maintenance for 30 years. A couple points on points. (1) The points plate wanting to be all the way over to one side is often because the points gap is incorrect or the advance mechanism seized. To make sure, check the points cam and centrifugal advance; disassemble and re-grease. Make sure the felt oiler has oil in it. (2) For static timing, I never used a light bulb. If your work space is quiet, you can hear the tiny "tick" sound when the points open and the ignition on. But it is far better to use a timing light, that way you can check timing at both the idle speed and that the advance works correctly, by revving to 3000RPM.
Thanks for the input Rick. I've worked on and own more than a few 750s among other bikes. The advance was free and spring tension felt good. I did my best to estimate dwell angle but never mentioned it in the video. Felt was good. I've just used the bulb method many times and it works much better for visual demonstration which is important for these videos. Correct on timing light which I have but felt no need to use after setting it as you see. The bike ran like a top so I left it at that.
I was workin on my ignition one day in the driveway and realized I could hear the click. I clicked it a few times and the dang thing started! Thankfully I was in neuitral.
I have a 1979 cb750 four K and it's locked up tighter than a drum, but was free when I got it. Only thing I've done is rebuild the carbs and try to start it.
What I know from the old masters, when there is a little bit advance on the ignition, the motor pulls nice & hard ! I really enjoyed that channel ! Thank you from EUROPE ! Is a good idea to keep in the pocket strip of sand paper to clean the contact if file missing ! Just fold small half inch strip and put between the contacts and sand a bit .How much fuel "eat" this monster ? :)
Glad you enjoyed! You should look up dental filing strips as they are a thin metallic strip perfect for filing points. Also these are pretty efficient and can get nearly 50mpg on flat. 45 is average
Bought a bandit 1200 once that had been sitting for a while..rode it home 20 miles no prob..but next morning had lost 1/4 tank of gas..the carby seals had given in.
@@BrickHouseBuilds yep...and still original 17 years old ..btw.. would love you to get hold of a Yammy FJ ..loved my FJ1200 .. actually one of my best favs was a Suzi GS1100g shafty.. would also love to see you do one or an 850 ... gettin warmer down here now ..out on the gsx1400 for the day this week...90'ish deg ... Got home a sweaty dripping mess..the new weight loss program...stay safe ...👍
@@squiddly-diddly I'll have an FJ1200 at some point im sure. They look amazing and after having an FZ1 and Bandit 1200 they would for sure be my speed for riding
I went ahead and did all the test that you have shown on the video. Which was great by the way. Caps read at 4.8. Primary 4.9 secondary 16.6. I added new plugs as well and new battery. When I tried do the timing test with light it wouldn’t turn on when the marks lined up or at any point when I rotated on either 1-4 or 2-3. Do you think the condenser is bad ? I cleaned off the points. Btw the switch was in the on position. I’m running out of ideas here bc my initial diag was no spark on any cylinder…
You sound like you are working your way through it. Id start checking for voltage where it should be and see if you have excessive drops or no voltage at all
Superb video & timely as I’m looking for a rough 550/4 to do up. Don’t Hondas use metric bolts ? I wince when I see the sloppy fit of your 15/16” spanner /wrench !!
Yes, of course they use metric. That isn't a nut being torqued, tightened, loosened, or put under any load so its perfectly fine to use for demonstration with the points.

It's not often anyone videos that sort of detail (appreciated though) on the points setting I was shown that you should always adjust the fixed plate first then once that is correct adjust the movable plate, this should avoid having to go back and forth between points. not too long for me, it did take two days of dipping in and out though :) :)
can you give me any idea about my 1978 yamaha 100 enduro kickstart only halfway thats why it wont start?its suppose to kick start all the way down,but mine seems like only kick start halfway?thank you very much
Outstanding video. I am a new subscriber and I am preparing to restore a Honda cb400F so your tips and techniques are just what I needed. Keep up the great work and thanks for your help! Do you have any videos on how to remove a stuck spark plug out of a barnfind?
Thanks Marcus! CB400f bikes are so cool! Although its not a motorcycle my buddy Nathan recently put up a video on plug removal for an old Model T he has started on. May be worth a watch. th-cam.com/video/Fu--1FEibi0/w-d-xo.html
New subscriber. Just got into 2 wheels last year and although I’m mechanical (basic maintenance and rebuilt and rejetted the carbs on my 03 Magna) I’m not at your level. Very informative. Can’t wait for your next vid on the cbx. Dream bike of mine.
Well congrats on the 2 wheeled machine! I appreciate it and am glad the video is informative. I'm definitely running behind on the CBX updates. I very much want to make progress there too

Glad you liked it and agreed, usually simple stuff but without proper tests you end up throwing parts at the wrong thing

Don't worry; I will stop sending as we know that you are a busy man. I get chatty sometimes. have a good one. Enjoying the show!!
Glad you have enjoyed the videos Alan
Better bikes than todays complicated machines 👍🏻🏴
In some aspects yes
Very informative, learned a lot! 👍 My first bike was a 74 CB550 super sport, this was like a walk down the memory lane 😊
Happy it had some worthwhile info in it
Do you think a 750 is too heavy for a beginner?
No 750 is a good beginner and intermediate bike I've rode dirt bikes on and off just got my 750 1973 love it learning lots
My first bike was a 78 cb550k, just picked up a 77 cb550f. The exhaust manifolds are a thing of beauty.
My younger brother sadly passed away in 2006 owned this same color CB 750 He really took extreme good care of it. I miss him a lot.

Thank ya! I'm sure you are watching part two now and in that I address the cracked covers with some epoxy to at least help it last a bit longer. The right side cover was bound to break and fall off.
@@BrickHouseBuilds I didn't see a part 2 - I'll be sure to check it out!
I really like your channel so much it bring bring good old memory of mine riding time in the mid of the 70. This bulb matter bring back.mine time. You CBX 1047 bring back those good old day which I own one. Now sure it history for me. I just love you channel very precise you give this old horse a good new life. I still live in the old world 🌎 ha ha.
IM glad you like what im working on Anson! I love these older bikes and making them run as they should really motivates me
@@BrickHouseBuilds Not like old bike. New generation bike may be better. But with all those groove electronics riding aids. To me is not too much of a fun at all. I kind of old school old bike you can get it fit. If you are out for a touring. The new one if they don't start cranking the engine you at surrender. You can look at the sky n pray. Old school you still got a chance to get it fit.
@@ansonlow7764 I agree but do like both. The older bikes take more care as they must be treated differently but are very rewarding. New bikes sure are comfy and smooth though!

Those nylon jets were cheaper and touted as nitro safe. Great Channel very enjoyable.
Thanks for the info! They threw me for a loop at first. I appreciate it 🙏
Excellent!! Thanks for doing the diagnostic demo on the timing. Really enjoying your channel.
Thanks Terry!
Lembro bem das Hondas com essa tecnologia four. Tive oficina e mexi em algumas mas nunca desmontei o motor, apenas nas Suzuki de motor 2T. Essas eram as motos mais cobiçadas da minha época. Parabéns pelo vídeo.
Thank you much!
Pure motorcycle. I love her as my Kawasaki W800 !
its amazing how much of a headache these bikes must have been for mechanics.... im amazed at all cb videos ive seen someone has always tried to repair different or find some janky repair etc
Yeah I've had to fix many many previous "repairs" that were extremely poorly done
Very educational dude. Thanks. regards from Sydney
Glad you found it so! Thank ya
I took your advice and am watching these videos. Im really getting a lot of great advice on what to look for. Quick question I noticed I have oil in one of my reflectors on my forks. I’m figuring it’s a busted seal, but it still has me freaked out a little. Dude are you In Missouri or Vermont? I’m in Oklahoma bro. Anyways you rock!! See ya.
I'm in Missouri. You should be able to inspect the fork for a leak
love the content makes me wanna find an old bike butt..... love my ZX6R, Z650 RS and ninja 400
All great bikes though!
I learned alot watching this video - thanks for sharing.
Glad it was helpful!
Nice old bike thanks for the info .
🤘🤘
Great video. Really appreciate the step by step.
Glad to hear it Anthony!
Awesome video. Thanks for this! Love this kind of content
Well I'm glad you liked it Mark! Appreciate you watching
Enjoyed the video and RIDE SAFE!
Glad you enjoyed!
Enjoying the video! Wee question - when setting the "fire" timing could you set align the fire mark on the crankcase then rotate the timing board until it lights rather than trial and error it?
Tomato tomaahhto. I simply prefer this method to be as exact as possible. It works well for demonstration. I like to test and retest.
Thanks for sharing your knowledge really enjoyed video. I read that one of initial checks on machine should include inspection of valves (x8). Would you agree or is it unnecessary?
Never hurts to check
Beautiful bike! Would love to restore a cb550 one day
Hard to beat a sunburst orange cb750. Cb550s are great
I owned the CB750 and did all my own maintenance for 30 years. A couple points on points. (1) The points plate wanting to be all the way over to one side is often because the points gap is incorrect or the advance mechanism seized. To make sure, check the points cam and centrifugal advance; disassemble and re-grease. Make sure the felt oiler has oil in it. (2) For static timing, I never used a light bulb. If your work space is quiet, you can hear the tiny "tick" sound when the points open and the ignition on. But it is far better to use a timing light, that way you can check timing at both the idle speed and that the advance works correctly, by revving to 3000RPM.
Thanks for the input Rick. I've worked on and own more than a few 750s among other bikes. The advance was free and spring tension felt good. I did my best to estimate dwell angle but never mentioned it in the video. Felt was good. I've just used the bulb method many times and it works much better for visual demonstration which is important for these videos. Correct on timing light which I have but felt no need to use after setting it as you see. The bike ran like a top so I left it at that.
I was workin on my ignition one day in the driveway and realized I could hear the click. I clicked it a few times and the dang thing started! Thankfully I was in neuitral.
Someone earlier didn't use JIS screw drivers on the points adjustments? Stripped out the cavity/slots?
Correct
I have a 1979 cb750 four K and it's locked up tighter than a drum, but was free when I got it. Only thing I've done is rebuild the carbs and try to start it.
This should help me a lot I have a cb750 four super sport.
Thank you sir
Glad you found it useful. Even just double checking the basic systems can be a good thing to do
Beautiful Bike !
It looks even better now with its new owner!
Can you convert these to a universal electronic ignition?
There are many electronic ignition kits for these bikes. Universal is questionable
Awesome videos, keep the CB750's coming.
Thanks Michael! Hoping to bring my blue 74 in the shop to get running soon
Great content for the moto community. Thank you for your service 🫡.
I appreciate that thank you
My dad just got a cb500t it's got my wheels turning for sure kinda dig it if I'm being honest
Those are great bikes. One of the best vintage twins I've ridden
What I know from the old masters, when there is a little bit advance on the ignition, the motor pulls nice & hard ! I really enjoyed that channel ! Thank you from EUROPE ! Is a good idea to keep in the pocket strip of sand paper to clean the contact if file missing ! Just fold small half inch strip and put between the contacts and sand a bit .How much fuel "eat" this monster ? :)
Glad you enjoyed! You should look up dental filing strips as they are a thin metallic strip perfect for filing points. Also these are pretty efficient and can get nearly 50mpg on flat. 45 is average
Bought a bandit 1200 once that had been sitting for a while..rode it home 20 miles no prob..but next morning had lost 1/4 tank of gas..the carby seals had given in.
Bandits do tend to have some issues with the fuel petcock. We're the seals you mention the origns between the carb bodies?
@@BrickHouseBuilds yep...and still original 17 years old ..btw.. would love you to get hold of a Yammy FJ ..loved my FJ1200 .. actually one of my best favs was a Suzi GS1100g shafty.. would also love to see you do one or an 850 ... gettin warmer down here now ..out on the gsx1400 for the day this week...90'ish deg ... Got home a sweaty dripping mess..the new weight loss program...stay safe ...👍
@@squiddly-diddly I'll have an FJ1200 at some point im sure. They look amazing and after having an FZ1 and Bandit 1200 they would for sure be my speed for riding
@@squiddly-diddly Can't say I have any interest in doing a shafty Suzuki though.
Those grips look like the same ones i had on my push bike as a kid in the 70s :-))
Yeah they were pretty bad lol
Excellent work again 🙂
Thanks John!
70s - 80s golden era of Japanese classic motorcycle bridge building: spoked wheels, straight fit, air vented engine, everything is right!
Agreed
Was wondering when adjusting the timing why not put the crank on the position you want the light on and adjust the plate until the light comes on?
This is per the book. Feel free to do it the other way of you like
Nice Video Never Seen Plastic Main Jet On Carb.
Thank ya! I hadn't either but now I know!
Great looking bike the old CB750
That they are! To me one of the best looking factory bikes ever made
@@BrickHouseBuilds And the Z900 .CBX 1000. 3 of the best looking
I went ahead and did all the test that you have shown on the video. Which was great by the way. Caps read at 4.8. Primary 4.9 secondary 16.6. I added new plugs as well and new battery. When I tried do the timing test with light it wouldn’t turn on when the marks lined up or at any point when I rotated on either 1-4 or 2-3. Do you think the condenser is bad ? I cleaned off the points. Btw the switch was in the on position. I’m running out of ideas here bc my initial diag was no spark on any cylinder…
You sound like you are working your way through it. Id start checking for voltage where it should be and see if you have excessive drops or no voltage at all
Superb video & timely as I’m looking for a rough 550/4 to do up.
Don’t Hondas use metric bolts ? I wince when I see the sloppy fit of your 15/16” spanner /wrench !!
Yes, of course they use metric. That isn't a nut being torqued, tightened, loosened, or put under any load so its perfectly fine to use for demonstration with the points.

Great content! Keep it coming .
Thanks Adam!
It's not often anyone videos that sort of detail (appreciated though) on the points setting I was shown that you should always adjust the fixed plate first then once that is correct adjust the movable plate, this should avoid having to go back and forth between points. not too long for me, it did take two days of dipping in and out though :) :)
Well I did the plate adjustment first and then had to adjust from there exactly as you say.
That bulb you used to test the timing, is that something you can order online? or did you jerry rig that together? Thanks. great video also👍
You could find a test light at an auto parts store or just rig some 12v thing up. Doesn't need to be fancy. Mine was just a spare bulb from a gauge
@@BrickHouseBuildsgreat ill try it! thanks for the reply 🙏
can you give me any idea about my 1978 yamaha 100 enduro kickstart only halfway thats why it wont start?its suppose to kick start all the way down,but mine seems like only kick start halfway?thank you very much
I wouldn't know where to start not having the bike in front of me sorry
Outstanding video. I am a new subscriber and I am preparing to restore a Honda cb400F so your tips and techniques are just what I needed. Keep up the great work and thanks for your help! Do you have any videos on how to remove a stuck spark plug out of a barnfind?
Thanks Marcus! CB400f bikes are so cool! Although its not a motorcycle my buddy Nathan recently put up a video on plug removal for an old Model T he has started on. May be worth a watch. th-cam.com/video/Fu--1FEibi0/w-d-xo.html
@@BrickHouseBuilds Thanks for your help!
Just got this exact bike yesterday. My seat is locked up (aftermarket lock). Once I get past that I can get going.
Thats unfortunate for sure but at least you can get past it!
Loving this content 👍
Thank you Neil!
New subscriber. Just got into 2 wheels last year and although I’m mechanical (basic maintenance and rebuilt and rejetted the carbs on my 03 Magna) I’m not at your level. Very informative. Can’t wait for your next vid on the cbx. Dream bike of mine.
Well congrats on the 2 wheeled machine! I appreciate it and am glad the video is informative. I'm definitely running behind on the CBX updates. I very much want to make progress there too
