Just as a tip, never run anything hard like a screw driver in the commutator groves cause that mushrooms out the com-bars and will eat the brushes fast. I prefer to use a toothpick. Great progress today! Actually starting to look like an engine now!
Thanks ATON for these videos! I'm also a mechanic by trade and while manuals are great and I have referred to them, I am completely new to bikes and this is exactly what I was hoping to find! Going to test my charging system now and will continue watching all these. I watched this and the clutch one last night and am excited to go service the bike now. Also wow the 750 Honda sure seems like a great engine to work on!
I'm a qualified mechanic and no matter how many years you're in the game there's always something new to learn. This guy is a great teacher and knows he's stuff. Excellent explanation on all that you do. Thanks and cheers from Down Under.
Excellent info in your videos here. I've always been taught, especially with the SOHC CB750, that one should avoid using gasket sealer, like the permetex you use, unless absolutely necessary because pieces inevitably come loose and work their way into the oil passages, blocking proper flow to the top end. In fact, I just picked up a '74 where the guy used RTV blue on the valve cover. Pieces are falling off all over the place. Because of this, I'm going to have to do a rebuild just to make sure it isn't mucked up. Also a good excuse for an 836 kit, mild cam, and porting. :)
I love this kind of videos, would be great if you start working on motorcycles again. The Ducati maybe? Thanks for posting so much great quality content. Greets from the Netherlands 🇳🇱
Terrific an extra installment great vids all of them. i'm an avid viewer and this made my night as well. All the best for the wedding and keep on hacking. Jay Rochester UK
Great post. Measuring a low resistance, the lead resistance of the probes may need to be subtracted. Also contact cleaner would be good cleaning rotor's contact with brushes. Would that convince carbon dust to stay away?
The reason you getting 0.5 Ohms instead of 0.2 is the resistance of the DMM leads. Short 'em together, and remember the value, then distract that value from measurements you make.
Great videos! They have helped me with building my cb750. Hoping you can answer a question. Do the stator and rotor sit in oil? I haven’t been able to find an answer, hoping you can help.
Hey, thank you so much for your videos. They are so educational and you explain things just right. I'm building my cb750 right along with yours and ine thing I'm worried about is the electrical. Mine is a rats nest and the original harness is long gone. I'm dealing with wires that I'm not sure where they go. Are you going to be installing a factor harness or will you be laying down your own electrical work?
hey, my stator and coil check out with the resistance spec but when I assemble it and start the engine I get no AC voltage. checked for ground faults and there are none. any suggestions. 1974 cb750k4
Are the stator field coil and rotor not supposed to physically touch or does it matter? I ask because These parts always look to be extremely close and I don't see how it would be possible to prevent them from touching when they are simply bolted onto a flimsy aluminum cover.
Sincerely friend is to ask a question you must catalog the bike honda cb 400 is that I could not thank you consegir-----------amigo cordial saludo es para hacerle una pregunta ud tiene el catalogo de la moto cb 400 honda es que no lo he podido consegir mil gracias
surprised it only had two brushes... my kawi had 4... it would spin the engine when cold with only 2 but didn't have enough torque to start the bike if the engine was warm.
Dean, I know I'm like the third person to ask this here, but still curious about your meter display - "OuCh"? Guessing it's for Out of range, and then Channel? Or maybe it's as a previous post surmised - you dropped it?
i like everyone else cant wait to watch your videos. if u would awnser a question i have i would appreciate it. ive been reading honda forums and i really cant get a yes or no. i have a running 76k without title. the only frame i can find for the last year is a 78f frame. should i keep looking or is the 78 the same frame? help?!
It was a surprise to see a mid weed video. Also on Jay Lenos youtube channel he has a video on a 70's cb750 if you havnt seen it you should check it out. It may give you some ideas of what to do with this bike.
Wayne Johnson I don't know of one. Brushless motors require an external integrated inverter/switching power supply, which produces an AC electric signal to drive the motor.
for a moment I thought we had the early realease as a gift :p. Something tells me you are way more advance into the bike. Looking forward for the carb episode. As always awsome infor and tips! thx for all that

Anton Babiy Good tip.
Oh use brushless motor haha
Your sweater has seen better days, Loving the videos! Keep them coming,
Kyle Cook I bought it that way...
Early release this week. :) Enjoy!
Thanks!
Great video! thanks from Colombia!
engine is lookin sweet man

every chapter in your book is a new chapter in mine. My to-do-and-check list increases every week haha, Thx again ! good info

Just bought my self a CB750 from 1972 so what you´r doing here is fantastic. Thanks alot.
Stefan Gödicke Sweden
I learn SO much with your videos. Thank you for being so kind as to explain things.
I have a 1974 CB750K4 on its way to me, this video series is fantastic, great work sir..

Love your videos, very technical and thorough. Building a 79 cb750f Supersport cafe, your videos are a godsend!
Fantastic,well detail....can't wait to see it on the bike.
Look like your meter is hurtin' there Dino! HAH!!! Thanks for the vid!.
I love this kind of videos, would be great if you start working on motorcycles again. The Ducati maybe?

Can't wait to here this baby run!

How can someone possibly unlike this video???
Wow its not even Saturday yet lol thanks for the videos and Keep up the great work.
Thanks really enjoying this series!
What???no Honda bond this week?com'on...Hey nice to see an early video, keep them coming
***** I had some on my pancakes for breakfast! :)
This guy is good. Very informative.
Great post. Measuring a low resistance, the lead resistance of the probes may need to be subtracted. Also contact cleaner would be good cleaning rotor's contact with brushes. Would that convince carbon dust to stay away?
Good vid. Informative as to how components work.
Hey,you make my day!I'm working on my FJ1100 Yamaha 1984 and wondering if I should check the starter,I will.Better be safe than sorry!
An early release...happy day!!
the dmm says OUCH on the screen haha
love the bike videos very inspiring since im working with my friend on his cb350fand v65 magna
I still wonder how did you find and sort all these parts from that pile.. Amazing work.. Hats off..
this guy is amazing
The reason you getting 0.5 Ohms instead of 0.2 is the resistance of the DMM leads. Short 'em together, and remember the value, then distract that value from measurements you make.
Great videos! They have helped me with building my cb750. Hoping you can answer a question. Do the stator and rotor sit in oil? I haven’t been able to find an answer, hoping you can help.
I want to know the same 😢

Factory harness. You can find a new one to buy with a bit of Google searching.
good good good, ya lo esperaba recien salido del horno jiji
hackaweek forever
Approximately how many hours do you think you have spent so far rebuilding the engine? Can't wait until you put it into the bike!
Hammer´n must close to 100 by now
hey, my stator and coil check out with the resistance spec but when I assemble it and start the engine I get no AC voltage. checked for ground faults and there are none. any suggestions. 1974 cb750k4

They don’t touch.
where do you find gaskets for this engine? I need to replace the stator cover and mine is the same engine. Thanks!
So the field coil and stator coil sit in oil?

Dear sir.. does the alternator fit to use on cbx 1000.. thank you
What have you painted the engine blocks with?? Looks really good.
Thomas Wallblom Previous owner painted it.
You really shgould be a teacher!
randy terrell I am, here on TH-cam. :)
***** haha and your average class attendance is in the thousands per lesson and growing!
surprised it only had two brushes... my kawi had 4... it would spin the engine when cold with only 2 but didn't have enough torque to start the bike if the engine was warm.
Okay, this might seem a dumb question, but what keeps the engine from continuing to spin the starter motor once it's going?
Darren Landrum The gear it drives has a built in one way clutch, also known as a Sprag clutch: en.wikipedia.org/wiki/Sprag_clutch
***** Thanks! I figured there had to be _something_ like that. :)
Another great video sir could you please tell me the length of the 6 millimeter screws for the sprocket cover thanks a mill
deputy53627 50mm
What kind of drill are you using? Is that a 12V impact drill/driver?
Matt Pezzino 12 volt Makita impact driver.
Dean, I know I'm like the third person to ask this here, but still curious about your meter display - "OuCh"? Guessing it's for Out of range, and then Channel? Or maybe it's as a previous post surmised - you dropped it?
I never looked it up in the user manual but it shows O.UCH when it's measuring resistance and the leads aren't connected to anything.
Ha ha - over-range on the multimeter says "OUCH". Too bad John Fluke didn't think of that.
nozmoking1 I think this meter IS a Fluke. It's a Snap On meter I bought in 1996. They made meters for Snap On back then.
What yea is that? I have cb 750 1992 an every starter I see is not correct one mine does not have that starter cavity I'm puzzled any help??
73... The title says so
i like everyone else cant wait to watch your videos. if u would awnser a question i have i would appreciate it. ive been reading honda forums and i really cant get a yes or no. i have a running 76k without title. the only frame i can find for the last year is a 78f frame. should i keep looking or is the 78 the same frame? help?!
Julia Bennett Keep looking. Not the same.
***** I will. thank you sir.
do you have to take it apart to make those measurements?
It's a pleasure to see you at work) Are you an engineer?
you need a TV show
love the vid man... keep on hackin!
perfect thanks
great starter video! glad i have a 93' , your starter looks like a bitch to take out and put back in if the engine was in the bike
25:28 your multimeter says "ouch". Should we be concerned?
It was a surprise to see a mid weed video. Also on Jay Lenos youtube channel he has a video on a 70's cb750 if you havnt seen it you should check it out. It may give you some ideas of what to do with this bike.
Mid weed video :) Nice Freudian slip!
You know what im not going to even edit that because I cant explain at all how that happened.
9FT inch pounds?
why does your multimeter say 0.UCH
Maybe he dropped it!
yeh I was laughing at the O.UCH too :)
Mine only says O.OOO... [!!!]
should have put some antiseize on those bolts before you put em back in that hard lol
25:19 ouch!
Can you not get brushless starter motors?
Wayne Johnson I don't know of one. Brushless motors require an external integrated inverter/switching power supply, which produces an AC electric signal to drive the motor.
How do I get in on donating?
Gregory Arnone hackaweek.com/hacks/?page_id=31 Thanks!
no new episode this weekend ? :(
maicito123 This IS this week's video. I posted it early, Thursday night. :)
for a moment I thought we had the early realease as a gift :p. Something tells me you are way more advance into the bike. Looking forward for the carb episode. As always awsome infor and tips! thx for all that
Thanks for watching! :)
Have you been mean to the multimeter? "Ouch" it says at 25:22 c".) :-D
Warning - NEVER put the shifter cover on first, put it on AFTER the Alternator cover.
First! :P
Just noticed that your sweatshirt looks like what a homeless person would wear. I guess this project is bankrupting you.
