I’ve got an ‘80 CB750C that I’m going to be stripping down and rebuilding soon. Bummed it looks like you’re no longer active on this channel but appreciate the videos you’ve got up on this! Super helpful!
Hi mate, These videos are helping me out no end with the re build i,m starting. Any news on when part 3 will be coming or the carb strip down and rebuild. Cheers mate, keep up the good work
Dude I know its been a few years, but thank you so much for these videos! I really wanted to give rebuilding an engine a shot and watching these two strip down videos gave me the confidence to give it a go. Went to a bike yard and what do you know there was a CB750 DOHC sitting there, so i picked it up for $250 and went to work! So far I have compeleted everything in video one. Engine was in rough shape, but its been a blast so far. Your tip with the shims to get the heads and clynders off was a game changer! The bottom half looks more intimidating for sure, but with the state of the engine I gotta give it a go. Gathering the tools now. Hope you get another shop soon, would love to see more! Cheers!
Looking great dude! I've been interested in picking up this bike for years, so it's nice to know someone has forged the way with a top notch rebuild tutorial! Thank you for your service.
No worries Jamie! The bike is wicked - very easy to work and very well engineered. If I were doing it again I might have picked a smaller twin-cylinder variant to save money, but that aside it's perfect.
As far as I'm aware there is no rebuild kit - you have to get all the parts separately. There is a set of gaskets, sets of stainless steel bolts, etc on eBay, then you're down to your Honda supplier for all the other bits.
Good day, I enjoyed your video's, step one and two removing the top end and then the bottom end. As this was done a while back already, did you ever do a third video to show the rebuild?? Please advise, I'm about to undertake step 1, remove engine. I need to replace a broken crankcase. Your video's are most helpful, thanks eh! (Jason in Canada).
Thanks for the videos. I’m currently rebuilding a 1979 CB900 FZ engine from a box of bits for a friend. I’m struggling with a few areas, but your videos have really helped me. Really appreciate all the hard work youve put into making them.
I'm about half way through this so far. My clutch was the same as yours so I guess its a mistake in the manual. Also, when you used the front axle to go through the con rods, I just did that to wizz the clutch off and didn't bother making a tool to hold the sproket. Same with undoing the alternator rotor thing. Worked a treat with an impact gun! like yours
you can also buy a cheap socket and dremel it into a clutch tool, super easy and works well! I split 3 crank cases and they totally varied on time. ~30 for two of em and the last one i got in like 5 mins -Super enjoy these videos very helpful to have a visual just wish you were 2 steps ahead as I am half a step ahead of this video! look forward to the next one!
Cheers Joel! I should have explained the clutch tool in more detail maybe. The tool I liked to is £5.66 at the minute. A 24mm socket in the UK is £5.99. If people have the time to wait, I know which route I would go with. That said, if you leave it too late I'm sure a socket + Dremel solution would work great 👍
My rebuild is going alright, I have my engine fully apart and ready to rebuild. I’m doing a lot of research now on what comes next which components need replacing etc. I’ve got 3 engines that are all apart so I’m measuring all components to see what’s in spec. My frame is off to the side tackling one thing at a time. Also big thanks for marking up that manual super helpful in conjunction with my clymer
@@joeldevries1174 ah nice. What parts are you replacing out of interest? I can't decide whether to upgrade starter clutch, chain tensioners and starter coils. I'm doing the Viton stem seals, stronger cam bolts and iridium plugs as they're so cheap it'd be mad not too.
Great video series! Love your work. I just bought a 1982 CB750C and will be rebuilding it top to bottom and front to back. Your videos are amazing inspiration. Thanks!
any chance youll be posting the rest i know its been a year but this is the most in depth teardown video on here would give anyhing to see the assembly
Oh man where was this video in september when I was spending $35 on a rotor puller and trying to decipher the honda manual! 😂 I found that you could tap the bits of overhanging cases with a wood block and hammer like in the vid and listen for the dull sound to turn slightly sharper as the gasket slowly broke free, this gave me a good indication that I was on the right track. Still probably took 2-3h though!
@Review Master "American style?!" You know cafe racers originated in London? On the North Circular? Which is less than a mile from where I live?! Anyway, I'm sure we'll all mourn the valuable input you'd have brought to the channel.
Hi I had a lot of trouble with the shift from gear 1 to 2 with many missed shifts. Then I found that the motorcycle racer in New Zealand Vince and hyde had a new specially shaped shifting star to fix this problem. . I've put it in but am awaiting the results of personal testing that promises to fix this problem...
Hi, just fell upon you vid, superb matey, very comprehensive 👍, I’m in the poof taking out gearbox as does not go into neutral when hot, might bore it out to 823cc whilst I’m at it. Anyway very good vids !!! Mark 😊
this is great! you're the man. thanks for all the effort and expertise! my old workspace was a storage unit! no electricity. it was challenging for sure.
Very nicely done and awesome job covering it clearly on video. Splitting my case was around 30 - 60 minutes I think, but getting the alternator rotor off was a RPITA. Ah the memories. Love the engine stand by the way.
@@naturalsIV It's already a fair bit of effort with the tools, workshop, headspace and just doing the work let alone producing awesome videos on top of that, I can only imagine how much additional work goes into that. The BMW is still at the planning stage, lots of looking, thinking, sketching, modelling and researching. Soon I'll be sharing some details.
Awesome set of videos. I’ve been using these to help me rebuild my engine. One question though. That o-ring that you mention when you split the case. Where is it? Do you mean the o-ring that is on the noz chain feed/oil chain feed?
Cheers Colin, I haven't quite figured out what needs doing on the top end yet but I'll certainly be filming and uploading it. Definitely needs a full valve job 👍🏾
Cheers once again. Not an easy job or sure. I have an ‘80 cb750c. I’ve often thought of an engine rebuild but would prob not take it on myself. Very cool.
Don't mind at all! Is your CB running well with pods? I hate the look of the airbox but there are so many scare stories about people swapping to pods and regretting it.
@@naturalsIV at first it didn’t run great. Then I played around with the jets. If I remember correctly I took the main jet( which I believe is a 120) and used it for the idle jet. Then took and drilled out another jet to 160 for the main jet. Also took the needle out and put a #4 washer I believe on it so it lets a bit more fuel through. After that it seemed to run ok. I didn’t have any problems with it
I thought these two parts so far were EXCELLENT! So easy to follow and detailed. I'm thinking of doing it myself, the bike I've bought has low compression and lots of miles. Quick question, I'm not sure if you have actually completed the rebuild or not but how are you/did measure the clearances for the bearings and piston rings etc? It's the one bit that I'm worried about
Thanks Frank! I'm still at the stage of the last video. Long story but life is getting in the way of this project!! I did read all the material on bearing / piston ring tolerances and measurement. Nothing too scary in there (and lots of good YT videos covering it) so I'd say crack on. The Motorcycle MD is great for all things Honda.
@@naturalsIV yea cheers. I've actually just had a quiet 2...3....4 hours at work and the plasti dip method looks very doable actually. You've given me the confidence to crack on so thanks for that mate!
Loving the video and the in depth content. About to start my engine rebuild over the coming weeks and looking forward to episode 3. Is this still on the cards? Thanks so much.
Afraid it's likely to be some time Jarrod. Unfortunately my idiot landlord is selling our flat so I have no garage space for the foreseeable future. If you follow the Haynes manual instructions an engine rebuild is pretty straightforward though. Good luck!
Hey Pierre, thanks for the nice comment! Life (work, daughter, charity stuff) has totally overtaken the bike this last year. I dearly hope to get it finished soon but equally some days I feel the weight of the world a bit too heavily and just want to hide! I really want to get back on it soon but it's definitely months off sadly :-(
@@naturalsIV Man sorry to hear that ....Hope you will be good soon in all aspects of your life ... have bought a 750c 1982 with 47 000 klm and I am trying to get myself up to rebuilding that engine (white smoke and brand new sparks that go black after running 15 minutes) but lack the will do it now, need to have one guy doing this from tearing it up to rebuilding it so I could follow the lead of the Same Guy,I do not want to go from one guy to another to get this done and so I will take time to finish the Body and paintwork ... I am a retired CNC machinist and now my way around tools but have never tackled an engine rebuild before, got to make room in my garage as I have small milling (just a hobby machine and a co2 laser taking a lot of workbench space....anyhow I will be making space this coming summer by selling those 2 machines and reclaiming a big 10 feet by 36 inch of workbench .. so will have plenty of room to work with ease putting the engine in pieces ... again take care man and hope all goes well for ya !
Great work! Was on the way to the shed to start the process of closing the crank cases after rebuilding the bottom end. Randomly came across this Channel! New Sub from me! I’m tempted to wait for your rebuild videos and do it along side you so I don’t miss anything 🤣🤣
Ha ha, cheers Wacker! New videos on the way. Unfortunately being full time child care for our little one means they're taking waaaaay longer than I would have liked.
Hey, great video! been watching ep1 and 2 over and over so I have a clue where to start when i disassemble my engine. When is ep3 coming out? I've just removed the engine from the frame (pain in the ass) so I'm about to start any day now.
Hey, thanks for the message! I've taken a bit of a break from editing to look after my daughter. Really hoping I'll be able to get the gear box rebuild uploaded by the end of the year though. Stay tuned!!
Great video! Is it possible to split the cases without removing the oil pump? My pump gasket seems to be really stuck on and when I attempted to split the cases, something seems to catching, on the front stator rotor side similar to what you experienced a bit of @ 20:00. Any idea what could be the issue?
Available from most DIY / hardware shops in Europe. They're called packers. Normally find them near wood screws as they're used to space woodwork when working with uneven floors and the like.
Hi enjoying your vids i was wondering if u were able to tell me whether the primary chain tensioner has an oil supply to a plunger to tension the slipper tensioner against the chain do u know if thats mains oil pressure or if it has a pressure reg to it im looking at modding my yamaha thank u
im pretty shure the tensioner/plunger works based on main oil pressure and not having a specific pressure regulator, if that were your question. the plunger goes from the oil pan and up to the tensioner, so im guessing its getting sucked not pushed considering its position.
