I spent my youth riding these motorcycles back in the 70s. All my buddies that had Honda 750-4 & Kawasaki Z1 900s. Its so nice to see younger people appreciating and taking interest in Motorcycles that made History and revolutionized the motorcycle world...
I have definitely been enjoying this bike. I always look forward to riding it
Honda did a fantastic job putting this bike out , so well engineered. Cheers Richie.
They made an icon
Any comment is a good comment, try not to be so thin skinned. Great content!
Im betting you don't get the comments I get daily. Its not a simple thing
Another cracking video....!!
Love what you are doing with this 750........,makes me want one just like it...!
The period charm of it is very appealing to me.....
Well done.......,keep the content coming...,its really good..
BG.
Thank ya Brian! Been a very fun and rewarding bike to bring back
@@BrickHouseBuilds yeah..,fun to follow along with you..
Been on the net looking and here (UK) and 100 £~$ examples are unheard off....!!
Almost every one is either a pristine survivor..,or a full restoration and all north of 10~12 Grand....!!!!
An amazing find for you.., and each video is a credit to you both in your 'vision' and presentation..
Well done...
BG.
That switch randomly working when it feels like it (usually when it makes you look stupid) hits home...I felt that, I live that ...🤣
I really love it when stuff like that happens and you get my legit reactions lol. Keeping it real
Had a brown one and a orange one I think they changed the cams in the orange one the brown one was a little faster . Toronto to Vancouver never let me down
Just want to say “thank you” for taking the time to put these videos out they are fantastic !
I’m just getting my old CB350four back on the road hence watching restoration procedures and these are my favourites on your channel.
Keep up the great work and all the best from the UK 👍🇬🇧
Well thank you so much Mick! Glad you enjoy them and hopefully find them helpful
Hi Mick, I am a brit living in Canada, I would love to have a 350 /4, how cool. Good luck getting it fixed up mate. 😄
@@tonyfurneaux3399Thx Tony, she’s all done now and looking good.
Gotta take the carbs off again on Saturday as she’s only running on 3. But yeah all done now. 🇬🇧
Hadn't watched the cam adjuster cleaning yet when I made the comment. Music can be muted. TH-cam 'M' for mute.
I see you engaged Safety Squints while blowing up that tube!🤣 This bike practically fixes itself every time you turn around.👍🏻 I kept that back rack rest on my stock 650C for when my wife and daughter want to go for a ride. It is actually very handy…carried a pizza 🍕 on the back with that bungee net!😂 Keep up the Great work!🔥
Indeed
One month late but here I am! Another great video - good mix of real time and time lapse footage. Regarding the music, put it where you want - you're the boss!
Excellent work as always, man! 🍻🤘💜
Thanks for the great videos. My first bike was a late 70's CB750, exact same as this blue one. You've inspired me to think about buying another old bike and spend some time fixing-restoring it. Your videos will be hugely helpful in knowing what-how to do it. Cheers Thanks
Well I appreciate that thank you!
Great, you're working on this right now. I'm a big SOHC 750 engine lover. The thing I didn't like about it was the slap happy cam chain (if it's mainly that?) idle sound. I don't how to make it in letters... maybe kkkrrrawww kkkrrrawww kkkrrrawww kkkrrrawww . I wonder if anyone has done any work on quieting the cam chain, or that sound? It never caused any problems when I had my 750. Maybe I'm asking too much? To me it's not a 'good sound' like a Ducati dry clutch, but perhaps others feel differently?
They are very noisy indeed
it's most likely clutch basket making that noise believe it or not. 76 and i think 75 had different clutch setups than the earlier models. I have same noise on my 76 and thought that was cam chain or primary chain. But they both checked out good. Honda had a field fix, where you would swap clutch plate with a goldwing double plate. This helps a little but not completely gone. noise goes away at slightly higher idle - 1500 and by pressing the clutch.
@@preez77 Very interesting. Thanks very much.
I think you're doing a great job on the CB keep up the great work.
Much appreciated Robert!
I loved the bike, thanks for the info on al the other stuff. I'm old school. a CB750 should never have a 4 into 1 (ugly,ugly), stock or 2 into 1 (if you can find any).
I think the stock pipes are ugly. We just have different opinions on them due to what them mean genersrionally to us. I didn't grow up with the posters and ads of these when new so I don't have the same memories.
@@BrickHouseBuilds. You have that right,.. One will do what suits you,.. Not everyone else.. 👍.. Honda did have a original 4to1 on the 75-78 Supersports,.. Don't saying it's the prettiest, but had a great sound,.. Inspection-crew liked them.. 🙂👍
Hi .a question for everybody . Is there a lockable oil tank cap for the 750/4
??????????
I am not sure but maybe someone will chime in. Also a good question for google and cb750 facebook pages.
Fantastic bike buddy 👍🏻🏴
Thanks Stevie!
I rode a '82 CB750K from California to NY and back in 1991. 9,000 miles in six weeks and it only needed an oil change and its chain lubed. What a great bike. I can't believe they are so cheap still. Love your channel dude!
Great job! All those little jobs add up to make this an excellent reconditioning. So far, I love all you have done for this old beauty. Regards from Canada 🇨🇦
I appreciate it Keith. It has been a very fun bike to do and I like all these smaller jobs as compared to my usual stuff. Its a nice shift
i like older bikes more and more, everything manufactured today seems to be controlled by computers these older bikes obviously have an electric system but the more complications that are removed the better, just like the old porsche 911 before modern electronics and computers and water cooling, very enjoyable and highly sought after
Agreed. I like to fiddle with things so this bike offers just that
I know you are a genius but you make it look all so easy, doable most importantly ENTERTAINING!!!
Oh yea I really solidified that genius part with the oil pressure light lol 😆
Great mod on the rack/carrier, fix on the cam chain tensioner and just the continuing innovation. Bike is gonna be amazing.
Thank you!
I watch all your vids because I absolutely love old Honda's and am currently putting a 1977 CB750A back on the road. Your teaching skills are helpful to me. Keep up the great footage.
Hi there
I need your advice on my 1975 Honda CB750k as a can’t find out what is the exact size for the Oil pressure switch sensor socket MM. could you please reply thank you.
My first bike was a 1982 Kawasaki GPZ 550. It was in pieces when I bought it. I did a decent restoration on it (I'm no expert) I had a hard time finding a set for it but it needed it badly. lol
Wow... fantastic. Takes me back to a brown one I had when I was 15. These are the best ones.
Haven't seen many brown ones!
These old CB 750 Hondas are so well engineered and incredibly reliable. As I stated on a different video of yours I was a Honda mechanic back in the mid seventies and I built mine out of the crate during my lunch hour. Basically, the only reason why I bought it was my riding buddy’s all had new 750’s for long road trips and they didn’t want someone in the group breaking down ruining their trip… traded my 63 xlch chopper for a 850 Norton commando which was reliable enough to ride long distance in the pack, then moved up to a new 750 Honda. Best thing I ever did!
Those things where bullet proof! BUT… the big sleeper of the day was the dohc 450 Honda… it was a 750 killer! I won every race embarrassing easy!
I agree on the 450! Those fly under the radar for sure. I actually have one that will be an eventual build but im torn between vintage race bike or dirtbike lol
Hi BJ, love the content mate, and its good to follow the book an drop washers three times, perfect lol. I was a whiner re music, your vids are good enough without the free crap music yeeha. Again I have to thank you for sharing your passion and knowhow. Your channel is the go to site, respect.
Motors made in the 70's era used better materials and lasted decades, also the engineering of the past was more competent in making motorbike engines, once the starter started immediately, today's motorbikes are more prone to damage because there are lots of computer accessories, gyroscopes and others, which useless ,, that's my opinion .. I like your vlog about motorbike repair as well as a solution on how to do a good service even without complete tools
Cam chain tensioner is ALWAYS seized. Simplest check is while it's still mounted to back off the set bolt, and turn the engine BACKWARDS to put tension on the slack side. This forces the plunger out (you can monitor it with a small screwdriver sticking in the backside), and then you work it free and then turn forward to put all tension on the front side. Then you're set; you can tighten the bolt.
Good tip!
Just so.ethung i picked up,the rubber mounting bushings seems to be tight put a drop of dishwasher liquid on them and they slip on easy as pie and washes away no harm no foul
Go on, buddy! The bike deserves it!
Its getting all the attention
Holy crap Batman it looks decent enough for what it is
I also have a very slow weep in my oil line, have not felt the need to replace it yet, maybe one day. It's always a treat to watch a master at his craft. I vote for a 4 x4 exhaust original.
I wasn't too worried about the leak but just know it would fail on a long ride so I have to be careful. Not a fan of 4/4, 6/6 exhausts. Already has the 4 into 1 as stated
A hydronic shop may be able to build a new hose using the oem fittings I do know modern hose is not as large
Good job on the gas tank. When you had the cam chain tensioner off did you notice a small (3mm) threaded hole in the back end of the cam chain tensioner? I recall finding one after I had removed the engine from the frame. I recall that I could screw in a small turn signal lens screw and it would act as an indicator to confirm the tensioner shaft moved. Saved me a lot of time later on!
I do not believe this had any threaded hole. I could have viewed from the back but I wanted to remove it anyway to get access to the oil pressure switch no it made for a nice demo
Love the CB750. I'm curious to know however if the Japanese 2-Strokes ever existed in the US ? Here in the UK, back in the 1970s, the Kawasaki KH250, KH400 were pretty popular, then there was the Suzuki GT750 Water cooled (AKA kettle). Used to see them all over the place.
Oh there were many 2 strokes here
Your welding looks great on the rack good save
77-78 CB750 "F" SOHC models had a shallower included valve angle which caused excessive wear in valve guides. Pistons are also different. '77 & '78 "A" & "K" models used the old style head.
I'd restore that CB750A, those were cool bikes! At least you can pull the top end in the frame on the automatic, as engines were extremely heavy with those bikes.
Cool video! Thanks man!
The A was very rough and I'm not interested in restoration at this point on any bike. Haven't found any joy in it
@@BrickHouseBuilds that's cool, top end should serve it s purpose well with the existing SOHC 750 if need be.
@@MM_in_Havasu agreed, the 750a is already gone though so no need
Great job on the tank, any ideas on removing dents of a chrome muffler, stock kz650?
Not sure on dent removal unfortunately
Where did you buy the carb rebuilt kit for a 75 CB750? (If you did) I’ve bought 3 off eBay but none of them fit.
Check out the earlier videos of getting the bike running. I discuss that and link where I got them. I don't use full kits but do replace seals/gaskets
I love this bike! I had a newer 1981 CB750 Custom. It, too, was a great bike.
I definitely love this one for sure. The dohc bikes were better hands down
Amazing welder and mechanic what a job buddy first class 🔧🔧🔧👍👌❤️
Many thanks!
Nice job. Would be nice to know what year the bike is. Thank you for reminding me the cam chain tensioner may be stuck. I haven't taken mine apart.
Its a 1975. I have a full revival playlist on it you would love
nice bike. I see the MO plates! I live in KC. Let me know if you wanna ride. My main is a 75 K5 750 cafe racer.
In near St. Louis so just 4 hours away. Id love to get out to Blip in KC again
There is a real "vibe" to the joy of working on old Japanese motorcycles! Cool channel!!!!!
Great video. Thanks. I also like your choices for when and what music you add.
I appreciate the input Adam thank you!
awesome video mate i loved the tank fix realy cool very enjoyable thanks for the video keep them coming
🤘🤘
I'm about to buy an 81 cb 750. It needs a stator. Any suggestions?
The charging systems on the dohc bikes are picky. Do a very thorough diagnosis and don't take the owners word for what it needs. It may just need brushes, may need a rotor, may need a reg/rec, etc. Regardless, all components need to be in very good shape on those for the bikes to charge and last.
Loving your series, great work bro, all the way from Ireland
Thanks so much 🙏
Great Job!.. Hilarious with the light,.. Had a situation back in the seventies.. Was goin' in for an inspection,.. Turned on the turn signal,.. Rolled into inspection yard, and for the first time in 8years, the freaking lights did not work.. the bulb was fine,.. An inbuilt devilish gremlin had grown for the day!..
Man that happened to me yesterday on this bike! Rolled into the inspection place and all the sudden the headlight didn't work! No fault found beyond a potential bad wire in the harness
@@BrickHouseBuilds wow,.. Yeah there are always some surprises within older harnesses I guess,.. 🤣. did you sort it out for them, - hope you'll got it through..!
You are refreshingly through
I wouldn't call it riveting content, but there are times I'm welded to the screen!
I see what you did there 😉
Riveting content? I was going to say it was ratcheting content!
You're a punny guy!
I LOVE this bike!
Hey me too!
Excellent first step but please put a 6 into 6 on it they sound awesome
Gotta be a 6/1 for an awesomererer sound 😉
Oh man that trick with the tube inside the tank is terrific man i love youtube
😉
Thanks for these videos on the CB750. I have a 76 CB750F that I'm wanting to get back on the road. So keep them coming!
Glad you find them helpful!
My first bike was a 75 CB750 F. I've restored a coupla GL1000s, the 79 I kept, patina & all after hundreds of hours of work. It's on its 4 stator (engine out to replace) Old bikes are a blast to ride, even though I have modern ones.
A kithen sink plunger works 90%of the time
Id feel like Id put a larger dent in the tank by pushing the plunger into it to make a seal but I'm glad it works for you
Have you fixed the cylinder 1 that use to smoked a lot?
There was no need. Check this video out that goes over engine health th-cam.com/video/mbpp8l_QLDg/w-d-xo.html
Just posting a comment for the algorithm...
Thank ya!
The oil sensor fix is why "mechanics hate engineers"
🤣🤣🤣 just impossible to access in a clean way
And here I was waiting on a POP!!! Cool & different video of clips for this classic bike. 😉🏴👍
Sure wish I got that pop lol
My low point of the vid was when you said not a parts bike, as I was going to ask if I could get the Comstars for my 75 CB 750F build.😭😭
I never had comstars anyway. It had spokes
@@BrickHouseBuilds LOL no the ones on the A.
@@leebenson4874 Well it is a parts bike though. I had the whole thing for sale for weeks. Even shared it here
@@BrickHouseBuilds $ for the Comstars?
Its already gone. I have no comstars
That cam chain tensioner fix is ridiculous. It's so easy on the 750! Pretty sure I have the same issue on my cb400f but I believe I have to split the cases to fix a stuck tensioner....
Pretty easy indeed. What year 400f?
When are you starting on the Honda CBX?
Not sure. Priority wise its all been customer bikes to meet deadlines and this bike so I can ride something. I go over this in my moving the needle video the past week
Love the series on this CB, love the camera placement, love the commentary, the work, the skill, the style of the show, everything👍. Subscribed. You do you my friend don't let comments dictates how you produce your one man show, time lapse it with or without music...you're the boss. Those welds looks awesome btw wish I can do that 1/2 as nice. Cheers!
Thanks so much!
I enjoy the videos on the CB750. As the owner of a 72 CB750 I like the way you are going with this project.
Thank ya much Gary!
This young man has wicked motorcycles skills! I learn a lot from his videos. Now I just need to find me an old motorcycle.
🙏🙏
That was well worth watching, hope you’re going to keep this bike, it’s a great machine, 👍👍👍👍👍👍
Thanks Pete and absolutely keeping this one
Never seen or heard of that trick with the inner tube to pop the dent out. Very impressed. Wonder if it would work in a 2 stroke expansion chamber exhaust.
That would be a cool place to try it. Probably a similar gauge but being a smaller area may make it very difficult.
What a great idea and result. I would have been really chuffed too!
Thank you much! Definitely happy with the bike!
I watched that fuel tank dent repair with a tube inside it here on TH-cam just as you did😁
Too cool not to try!
@ 28:14 I am here for the content, not the music. The music is not terrible.
Music is part of the content. It will always be a part of my channel. Creativity and functionally it serves a purpose
@@BrickHouseBuilds I wasn't criticizing the music. I meant that I am more in tune to what you are doing and what I am learning.
Please don't destroy my faith in younger generations by doing anything too wacky with the seat! 😬
Seeing how I've been doing the rest of the bike how wacky are you expecting me to get?
@@BrickHouseBuilds I dunno, but you have a great looking seat, but it wasn't fitted, and a whole seat video coming up? At the same time, you said you want to have a chat with us, and we're thinking wrong! Hopefully I'm thinking right......bike looks great, very tastefully done. 😊👍
Reminds me of how I did bikes when I was young, driven then by lack of funds!
Its on the topic of perception and flawed logic on whats important
An old mechanics trick was to check wether the cam chain tensioner moved was to take a Allen wrench put it in the end of the tensioner to check if it moves
I could see that for sure. Since it was coming off to do the oil pressure switch it made for a good demo
Complained about the seat? These complainers need to get their hands dirty.
Hundreds of comments from day one just pointing out the seat
@@BrickHouseBuilds Amazing. I like the torn seat! Battle scars.
OK, then, I'm not going to comment on that small scratch on the valve adjuster lid...
That tank dent repair was amazing!
I’m excited like a kid lol the fact that worked is insane to me 😂 I gotta try this some day
Give it a shot if just in the name of fun!
Is that an Ed Kemper Timesuck shirt at the beginning?
Keen eye!!!
@@BrickHouseBuilds love the videos man, just bought a 75 cb550 so I’ve been delving into some how to videos on these bikes. They’re beautiful but carbs are a pain in the a$$.
Just don't overthink the carbs and make them a bigger problem than they really are. People do that with wiring
GOOD LOOKING BIKE,. I HAVE TO GET MY BUTT MOVING ON MY 350 BUILD!
Get on it! Also, thank you!
I thought it would look just as good if you put a leather patch on the tear on the seat.
The existing material is almost hard and brittle so it wouldn't hold anything
Man, I really wish we'd heard the pop of the gas tank dent coming out. : ) Oh well. I always learn something from your videos. Today I learned how easily the cam chain tensioner comes off and on and what that screw is doing when I tighten it down. I may have to take mine off to inspect it. I can't tell if anything is happening when I do the cam chain procedure.
My heart was broken when I readjusted and put in a bit of air to check the direction and it popped out. Would have made for SUCH a cool video lol. Definitely check out the tensioner if you are questioning it
Do I see a new series coming...Dr Dent Popper!
😂
I enjoyed the video.
Glad you enjoyed!
Cheers Richie
🍻🍻
Lots of stuff in the works! 💯👌👊
You know it!
Happy to see the tank turned out so well . Looking forward to seeing what you decide to do with the seat . Repair, replace, clean, and condition !
Thanks Maxx. I actually showed the seat in the video
@@BrickHouseBuildsThx I noticed that, I'm stoked ! If it needs cleaned , and or conditioned hope you show that too !
250 foot lbs !?
You know that was sarcasm right?
Man that 78 is the same bike my dad had ! Where can I find one? You should get that one running.
I sold that 77A parts bike a while back actually.
@@BrickHouseBuilds I wonder if there's anymore around? Where or how do I search? If you don't mind sharing your secrets?
@@66tdarren I find classic bikes everyday on Facebook marketplace. They are everywhere actually. Just check local listings, ebay, Craigslist, bring a trailer, etc
@Brick House Builds thanks man. I'm digging your channel BTW.
@@BrickHouseBuilds I sure would like to find one and get it to you for a rebuild. You know your stuff. What part of the country are you located?
Fix the seat!
Can't tell if thats a joke or not
Wow!
Thank you
This Bike was the absolutly Dream wen i was yuang. But only a Dream. 🥰
Never too late
@@BrickHouseBuilds thats wright but now i am 64 and ride my flying Brick. BMW K100 RS. 🙂🤟
@@rolfbley1373 nothing at all wrong with those!
@@BrickHouseBuilds 😜👍
Tank... so cool. Never saw that done before.
Nor had I! Looked like too much fun not to try
Don't you supposed to rotate the motor after you release the tensioner?
No. You set the engine in a specific position then perform this procedure.
@@BrickHouseBuilds I thought you were supposed to roll the engine over one revolution to take out all slop out of the chain.
@@frankc1430 The tensioners job is to remove the slop
@@BrickHouseBuilds it's meant to put pressure on the chain but you have to take the slop out of it. It's not a automatic chain tensioner. You need to pull all the tension out of one side and keep the slop on the other and lock it in with your tensioner.
If thats the case all the Honda service manuals are wrong then per your information.
Great info on the 750
Glad you liked it!
6:40.....its 🎩 magic
Magic I wish I had recorded 😪
Great work matey, i noticed some head fins brocken on the 750four, im pritty sure they can be welded and built up, i see Johnnysvintage motorcycles rebuilt broken fins on a Z900 Kawasaki, but i supose you would know they can be repaired. Great vlogs👍🏻
Thank you and yes some cracked fins but O don't want to weld them while still mounted to the jug. Check out my video on fin repair on my cbx restoration th-cam.com/video/4k8RUivsel8/w-d-xo.html
when you said "crank this to 250 ft lb" I literally choked on my own spit.
🤣🤣🤣
