- It's finally time to remove the engine from the Honda CB750 Cafe Racer project. It's a one man job if you place the engine onto a stand then remove the frame from around it.
I know the first part of it isn't in focus, but hey, I was running out of time to re-film the start.

I'm enjoying the evolution of your channel. From the intro music to the builds, it keeps getting better. Thanks for what you're doing.
Thank you, it's a slow progress but it's getting there.
Editing style has evolved, the mood created is a lot more personal. I don't know what you did, but a huge thumbs up. Great content
I have swapped back to my 50mm 1.4 lens for the filming, it could be that. Thank you
Love your videos, you've inspired me to create rather than restore. I've got a 92 CB750 which I was going to restore but I thought it looked a bit boring so after finding your GS build videos I decided to go down the café racer route. In the past couple of weeks I've started putting it back together, I'm just putting the wiring loom back in which will need some modification to get it to fit on the shortened frame. Like you I struggled to get the engine out, nearly causing major back injuries to me and my brother. Putting it back in was easy, we put the engine on its right hand side and lowered the frame onto the engine. Its amazing what you can find on TH-cam. I don't know you manage to build, video and post but I'm glad you do. Keep it up.
Yes, definitely the neatest way, I did that with the GS to avoid scratching the paint. Best of luck with yours.
I am so pumped for this build you Inspired me on day one of the gs and cx build ... I have the same bike I am building Awesome to see your ideas and you do it also
Amazing, more CB videos coming, engine and cowl.
Just starting my own build, I find all your videos I've seen so far very insightful and VERY entertaining. Thanks for sharing the struggle 😆
Thanks for watching and best of luck
Another great video 👍 hope to see a tear down and rebuild on the engine got mine coming up soon and every bit helps.
It'll be very soon, full steam with the build.
I bought a '81 CB900f after watching some of your first videos, i never had a jack or someone to help to remove the motor, so i ended up stripping the bike down to just the frame with the motor attached, laid it down on its side and lifted the frame off the motor and put it back in the same way.
That's a handy way, I put the Suzuki Engine back in that way as to avoid scratching the paint.
You really deserve more views man
Thank you, that's very kind of you to say.
I am doing a 1979 CB750 build and also found the oil to be very thin - it was mixed with fuel. After stripping the engine we found all the bearings were toast and the crank was so out of spec it had to be replaced. The con-rod bearing shells are also specific to each CB built and each con rod has a specific coloured bearing shell (upper and lower). The con-rod bolts also apparently need to be replaced with some type of unobtanium bolts from who knows where. Lets just hope your engine is fine :)
It'll be having a full tear down, and yeah I've heard the bolts are about £10 each. Let's see how it goes.
When you do take the engine apart and rebuild it PLEASE PLEASE be very detailed on what you do. I have searched youtube for years and not found any very good build videos of the DOHC CB750. I too am building a 1982 CB750C and the engine I suspect needs some internal help so this would greatly benefit me as well as others in my position. Thanks
Check out hack a week:

I second this!
Super excited to see this build come along!
Will do.
I've seen this build, not sure how different the internals of the SOHC and DOHC are (apart from the obvious) but we'll see :)
Check out Peter Anderson's channelth-cam.com/play/PLSL5PUw3f6de-DyXANtaDfPQqxZbQE2LK.html
I agree, I like this editing style A LOT. Also, please try to go into detail when exploring the exchangeable seat as i would like to do something similar for a Goldwing GL1100 im building now!
Absolutely, I think that's going to be the key part in this build. That and a polished fuel tank!
I am building a cb 750 year 81 myself. I am done with the frame and loop work. I am excited to see what you plan for the engine because mine looks a lot like yours ( partly dirty, ugly, old).
Excellent, the hoop and frame work was carried out last weekend on this one also so it'll be next week's video. The engine is going to be stripped and vapour blasted.
Geez mate, that is a large lump to wrangle. You need a lift and you need a mate to help. The removable frame section is a great feature. I wish I had your videography skills, I always learn something and get creative ideas when I watch your channel. Keep up the great work, Andy
Thanks Andy, the camera helps make the illusion that something as 'simple' as removing an engine is exciting.
Aren't you gonna do a design video of this thing like you did with the CX500? Also, for the dual/single seat interchangeable setup, check out the Royal Enfield Continental GT's rear hoop. I think it comes with an interchangeable double and single seat option which uses the same hoop.
Not for this one, I'm keeping the end look under wraps, and I don't thnk it would do justice for this bike in Photoshop with what's going to be done for it. I'll check it out, I'm sure Triumph had the same also for their Thruxtons.
The “please wait screen” cracked me up 😂
Cracked my back that's for sure.
I have a 1979 750f and I think the valves were bent when the timing chain slipped. Do you know of any way to remove the head without having to remove the entire engine from the frame? The problem is the clearance above the head bolts (to the frame) is not enough. I'm wondering if it's possible to lower the engine two or three inches to give it enough clearance.
Only by removing the engine I would say
Love your videos. Im thinking of selling my little project I have, as its not getting the time it needs from me, and theres a few things ive found which I think are not cost-worthy reapairs :( In the future I'd love to get a bike with more aftermarket support and guides from people such as yourself :D
Ah that's a shame, but I guess if it gives someone the opportunity to bring it to life then there's a plus sign, a shame when bikes don't get to see the road.
My Lugs and nuts are rusted too. Do you leave it as is or you replace a new one. I dont know if its worth de-rust myself.
I replace everything that I can with new. I like to do that as I know then it's done.
ahahaha I was wondering about the weight of the frame and the video just cut out ahhahaha... that kind of stuff make your channel more down to earth and really that garage feeling...not that I want you to hurt your back haha but I really like the way you do the stuff unpretenciuly and with the stuff and tools you have in hands! I was also thinking if you have a special system to mark the bolts and diferents parts of the bike so you don't get messy and confused when you rebuild it? although great video as always...and I agree the editing is great :) !! God job
Ha, it's part of the fun, making mistakes and misjudging things. As for the bolts I tend to have a good memory of what goes where by just seeing them. Engine bolts are a different story as I'll need to make a template to keep them.
Ey man!
I like your videos about cb750. 👍👍
Do you know if it possible to install crank start in this kind cb750 (with electric start)?
Thx!!
Question is do you want he massive job of doing it? I’d just stick to the electric start. You’ll soon regret having to kick this.
@@forthebold Really?? The kick crank start is nostalgic, but, do you think that is worst? So, I think that I will choose electric start. Thank you so much. Keep it up, good job.
Have you ever tried to kick start a bike that refuses to start cold or flooded? Try it with a bike with no electric start and you’ll soon be wishing you had electric start.
So I'm looking at an 81 Yamaha XS850 Midnight special tomorrow. The guy said that the engine was seized but he freed it. Is it a gamble buying a bike that had a seized engine?
You'll need to strip it all down to check the ports & pistons. If you have the time & possibly money it's worth it.
BikeShed cap
Any chance we could see a Triumph build at some point later? Love the vids, but personally, I prefer British bikes
I would love a triumph build but they cost so much here.
i must have the name of the intro song to your channel bruh
Just take off the side cover and put a hydraulic wrench to the crank for checking the compression.
I wish I had one :(
Perfect
Thanks
I hate how easily your engine mount bolts came out!!! :P I stripped down a Kawasaki half the age of that CB750 and some of them needed to be cut off with a chisel! :O Nice work though. :)
Sometimes lucky, sometimes not
Lol ,those old bikes are beastly heavy
Yup, this one is the heaviest of the 3 by far.
There is an easier way to get the engine out - tip the bike over with the engine resting on an old tyre and, after removing the wheels, lift the frame off the engine.
Yep, that's what ended up happening in the cut scene, as well as putting the engine back in, this one definitely is a heavy lump.
How much does the engine weigh
More than an elephant testicle that's for sure. Googling though I found this
weight. 200-225 lbs
For The Bold - dreegez wow, that is very substantial compared to an entire new sports bike.
About all you need is a 10 12 13 17mm sockets wrenches for metric bikes lol
Bruce Kirk you never need 13 mm on anything that comes from japan. 12 or 14 never 13, not with bikes nor with cars. Because 13 is bad luck. No lie.
@@thestef194 my sohc 750 uses a 13 on the brake lever or the kick starter i forget witch one but im positive it was a 13. I could check
BUY A DANG POWER TOOL! that sweaters like 140 bucks
Easiest way to get the CB750 engine out is to lay it on its side and lift the frame off the engine.
Secrets exposed, that's what I did when the video went off ;)
Wait, removable down tube? That's cheating!!! :)
Yeah handy with the DOHC
