You got the best channel for these old bikes it's nice to see these older bikes giving some loveI've been building and riding a 80 gs550l for two years it's almost done now
Wow. Super informative. I have a CB450. You have inspired me to pick up a cb750 and a sl350 as well. I can't get enough of these old bikes. Subscribed!
Hackaweek, you have already been a great help to me as I rebuild / restore my '76 BMW R90/6. Even though your bike and mine are totally different, I find some of the same struggles you tackle and learn a lot from you because I don't have a ton of specialized tools in my garage either. If I get to any of the events in NC, I'll look for you.
Thanks for posting all these videos, I'm just starting a similar project with a 1984 Honda CBX750fe and I still have all this stuff to look forward to. Your videos are great to watch and I'm learning loads. Cant wait for the next one.
Jeez, the memories. I had four CB750s: two K2's, a K7 and an F1. The K7 was probably the best looking, but those motors take some working on. As I recall you cant get the rocker cover off without dropping the engine out of the frame. Definitely not designed for working on. Great video.
I do really love your work! I've done the same to my CB750F2 about 10 years ago and it's so much fun to watch your detailed videos!! Looking forward to seeing the final look of your "cafe scrambler" project :-)
In the past I've just let the chain sag into the case while I put the cylinders and head on and then fish it out after with a telescopic magnet. Seems easier than trying to hold the chain while dropping them on. I didn't know about the measurement specs for the chains ... definitely good to know that. I just replaced mine. However, my engine rebuild ended up costing ... a lot.
ive read if you leave out those little 8m bolts that keep the rocker shafts from spinning it allows those shafts to rotate, thus reducing uneven wear. its talked about on a major forum for this bike.
The shafts have a waist on them. The 10m center bolt holds the shaft in place. The 8m bolts were added later and designed to reduce a little bit of noise by preventing the shaft from rotating.
What works even better during the cylinder/head install is to hook a bungee strap up to the ceiling and connect the cam chain to it. Then route it through the cylinders and re-connect it to the ceiling when dropping the jug into place.
Hmm.. although, it was quite interesting, it raised a lof questions. Are you sure, that that 6 mm clearance in the primary chain is enough to assemble it? It has like a couple of a thousand miles in it max. When the washer is harder than the bolt and/or the surface, it eats up them. if the washer is softer, it can be replaced, the bolt and the surface remains intact, and the tension holds. too hard washer may act as a slide bearing.
awesome. dean i have question. i bought a 1976 cb200t and i took it apart and rebuilt it. then i bought a 75 cb750k. then i bought a 74 cb750k. and now i want to buy another one. is this normal?
Hell yes brother! After you finish one keep doing it over and over and over!LOL! Just remember we are enthusiast's not Hoarders! LOL, hope all is well for you and your bikes brother
Nice video again! Learning alot! are you also goiing to clean the crankshaft? Drill out the oil ball galleys, remove the sludge that 30+ years has left behind put in plugs etc? Öre do you skip that part?
For crankcase bolts what I do is simply screw them in one turn very loose and make sure they are all spaced out equally which should be about 1 cm from the top.
when you're putting the cam chain on the gear up top, could you put the two together and slide the cam shaft through the gear and into place all at the same time?
Hey Dean, perhaps it's time to get the mig welder out and build yourself a bench. I'd hate to see that engine hit the ground or worse still land on your foot. Keen as ever to see the next episode.
Given you didn't know the state of the cam chain, it might have been worth just buying new, rather go thru all that you did. There probably is a way to measure chain wear by holding flat by one end and see the "droop". Excellent video!
im interested in knowing where you got the images telling which and what bolts you need,i have looked on House of Honda but can not find them,i have the CB900F 1982
this how warranty is done you would think heck just new chains but if one under warranty had problems these measurements would show you where you are off. this is the hard way its also the difference between 6 months of riding before scattering the engine or 200k miles without any problems
Jeff Bankston At a cost of $250 for new primary chains, I'll trust the spec sheet that says mine still have a lot of wear left in them and leave them alone.
Yes that's what i'm saying to many people would change them for no reason. These young guys now days want to just change everything I remember going to the junk yard and pulling heads to find .020 over piston's on car engine to save that money for a hot cam. Today its buy it all. This is a Honda new rings and gaskets and keep on driving this is how its supposed to be
HackaweekTV Why did you take the time to put assembly lube on the crankshaft, but not on the camshaft? I would love to think I would be able to do a build like this from scratch, but to be honest, it's very probably beyond my ability. A great video and I really enjoyed it. Thanks.
he most likely didn't lube it, because he is going to have to take that off anyways. hes just checking the length of chain. But all the other stuff he lubed he doesn't have to take a part. just has to put the pistons back in.
ah yea thats what i figured! haha thanks for the reply. I have been watching since the sabre. Im also working on a yamaha xs850 cafe build. Had to get the head worked on, and have been putting it aside since i got it back. But yea i do alot of putting together and taking back apart.
hi! question: why assembly lube instead of motor oil? is it good to mix 'em up? Isn't oil good enough? or maybe not thick enough and may disappear from it's position?
I always just let the cam chain lay in the bottom of its galley. Then once you assemble the topend just grab it with a magnet or a wire bent into a hook. I see so many people in videos wasting so much time playing with the cam chain. You would think such experienced mechanics would realize such an obvious thing.
also love the videos, but to be honest I cant wait until the engine is done. I actually fell asleep watching the last one. Sorry man haha but Its so dull to watch. For me that is!
you should dedicate to one project at a time, and finish it first before jump to other, I`m a huge fan of the channel but it kind of suck when you have to wait this much for the bike videos which is main one and the cooler. don't mean to be rude it is just broken english.
Hey man I've got some electrical gremlins on an old cb 200 and I'd like to exchange some emails if it won't take up too much of your time I can't find a way to send you a message other than this comment

King of Builds Bud. Terrific graphics and everything you need to know.
I'm rebuilding a 72 cb750! these videos are such a help. looking forward to seeing it all done!

I've been wondering why people think it such a calamity for the chain to drop into the case. So, there's no real reason?
As long as your cam ends up timed correctly with your crank then I can't see a reason why it would matter.

Ste W So if you do that, what the hell keeps them in place?!

Excellent series.

really nice in-depth series, i'm learning so much. you have a new subscriber and fan =)
That copper wire idea was smart

Thanks man! Your skills are amazing and totally understandable your teaching. Thank you for sharing and not be stingy.
Bad ass.. Had no idea you made videos like this.
great! looking forward to episode 13!
Awesome video. Tips & Tricks. One day I may try this but only on a donor engine first!
Great videos.. looking forward to more.. thanks learning from this..
awesome. dean i have question. i bought a 1976 cb200t and i took it apart and rebuilt it.
then i bought a 75 cb750k. then i bought a 74 cb750k.
and now i want to buy another one.
is this normal?
Hell yes brother! After you finish one keep doing it over and over and over!LOL! Just remember we are enthusiast's not Hoarders! LOL, hope all is well for you and your bikes brother
if you went through all the trouble of rebuilding the motor , why not just new chains ?
great video im learning so much and i feel like im building this with you thanks agian!
enjoying the build
Nice video again! Learning alot! are you also goiing to clean the crankshaft? Drill out the oil ball galleys, remove the sludge that 30+ years has left behind put in plugs etc? Öre do you skip that part?
Why are you using assembly lube now when everything has to come back apart?
Chris Doms To keep the bearings from getting scratched or damaged.
Keep em coming!
For crankcase bolts what I do is simply screw them in one turn very loose and make sure they are all spaced out equally which should be about 1 cm from the top.
great video man, as usual
you're the man!
when you're putting the cam chain on the gear up top, could you put the two together and slide the cam shaft through the gear and into place all at the same time?
damn good progress! cheers for sharing it is really helpful for a begier seeing this come together :)
Hey Dean, perhaps it's time to get the mig welder out and build yourself a bench. I'd hate to see that engine hit the ground or worse still land on your foot. Keen as ever to see the next episode.
loloaqici82qb4ipp I have a plan to build out one side of the garage with one long wooden bench this winter.
Given you didn't know the state of the cam chain, it might have been worth just buying new, rather go thru all that you did. There probably is a way to measure chain wear by holding flat by one end and see the "droop". Excellent video!
Chris Edmonds A lot of what I do in videos is for the benefit of others doing similar things. :)
im interested in knowing where you got the images telling which and what bolts you need,i have looked on House of Honda but can not find them,i have the CB900F 1982
Hi. Great tips! Please tell me did You paint crankcase or maybe glass blasted?
You are an artist :-)
Did I miss something? No sealant when joining the engine halves?
Great video thank you
this how warranty is done you would think heck just new chains but if one under warranty had problems these measurements would show you where you are off. this is the hard way its also the difference between 6 months of riding before scattering the engine or 200k miles without any problems

Also, if you don't end up using those forks, I'll gladly purchase them from you.

Ace00731 Everything is coming back apart. There are parts in the lower end that are missing. This is all just a temporary assembly.
ah yea thats what i figured! haha thanks for the reply. I have been watching since the sabre. Im also working on a yamaha xs850 cafe build. Had to get the head worked on, and have been putting it aside since i got it back. But yea i do alot of putting together and taking back apart.
Great vídeo.
Congrats.
GREAT video. THUMBS UP
When is the next part to the CB750 build coming out?
As said above, I'm getting the garage reorganized. I won't be working on the bike until after the new year.
That is going to be a bear to do with only one set of hands.
hi! question: why assembly lube instead of motor oil? is it good to mix 'em up? Isn't oil good enough? or maybe not thick enough and may disappear from it's position?
Szymon Krasuski Assembly lube is very clingy.
تقفيل رائع لمحرك ريس الله عليه
Hey can you give me the Link from the Site where i get the plan for the screws?
Was no gasket cement used between the crankcases?
This was just a test fit.
That dam chain!
Donde puedo conseguir piezas para mi honda enton en mexico??
I would think you would need to use a new piece of cloth for each bearing surface.
Hey what part of NC do you live in? I moved to Grandy NC last year.
Argentina lindo videos quiero una honda soy fanatico

10:57 no glue at all?
Not final assembly, just an inspection and test fit.
@@HackaweekTV oh ok, that's why.
@@fvmmecanica1135It's best to test fit the parts 1st before you start putting any screws bolts/washers on 💁♂️🏍
where can i buy an honda engine in kit like this one in the video and then assemble it myself? keep up the good work!
Great job!! I think that houseofhondaparts.com doesn´t exist anymore. Maybe another website? Saludos desde Argentina!!
Hey! What happen to this project? Did you give up?
Getting the garage reorganized. I won't be working on the bike until after the new year.
also love the videos, but to be honest I cant wait until the engine is done. I actually fell asleep watching the last one. Sorry man haha but Its so dull to watch. For me that is!
Have you given up?
No. I won't be working on the CB until after new years.

without the gaskets all the measurements for timing chain would be just waste of time dude.
31:35 XD
What a load of pissing about, just replace the cam & primary chains.
Omg 3rd
1st
Omg first lol
