This week the engine gets filled with oil, cranked over and tested for oil pressure. Do you like this video series? Donate here: hackaweek.com/h...

[@massoudzadeh3394]

It's amazing that you explain piece by piece, part by part. You don't leave anything behind. I have learned so much as you explain this. Thanks so much

[@joeking9933]

Great Job and I am learning so much. bought a new 74 CB750K as a young 21 YO Marine Sgt and hated selling it. now have a 76 CB750K and will never let it go. Thanks again Ret USMC Semper Fi from Pensacola Fl

[@mycolthefungi]

Ive been watching your videos EVERY week for a year now and its just so darn impressive how much you know without having to look anything up. I just hope I have as much knowledge as you do one day...slowly but surely.

[@MerlinZener]

what a great series of videos. I can't believe it's already 22 episodes in, at roughly 30 minutes each, and still ignition and carbs to go! Really goes to show, when you look at a bike that's been rebuilt, just how much work has been done.

[@nowayjose20]

If anyone's wondering, there are actually aluminum crush washers that go on the oil lines to the tank. They were probably still in the lines when you went to connect them, Dino.

[@IchibanMoto]

awe... the intro got me ! You should totally have fun with a feature length BS hipster bike video ! btw: nice work on the CB dino !

[@DeanSegovis]

Ichiban Moto I might do that Ichi. Homage to your channel. :)

[@zagzigity]

+Dean Segovis Haha!! Intro got me too! 'Danm! Dean gooves to some to beats!' Great channel by the way!

[@richie9777]

Dean I missed ya last weekend. Sunday morning wasn't the same without seeing another step closer to seeing this bike take shape!

[@blolo8]

Hey! I just watched the whole CB750 series in a day xD This is crazy, I really want to get busy on a project like this. Thanks for the dedication, you are awesome !

[@josselinledent9633]

A lot of work done so well !! Cool to see that all the work you done on that works good. Can't wait to hear it runs! A french fan

[@Langdoncaptain]

Ok, now I am binge watching you. Congrats on your impending nuptials. My CB550 race bike is part CB750, and a bit of CB900 as well. Love what you are doing, keep up the good work.

[@JC-sg1hd]

Such an awesome series. Can't wait to see the finished bike!

[@a94120905702]

Loved the intro!!! Can't wait to see the engine running

[@jeffbecker7703]

WOW! Exciting!! No, not the engine moving, but those SpArKs!! Hope that didn't mess up that pretty aluminum block with nasty looking burn marks. Be careful there, Dean.

[@beaudanner]

You're a genius and I absolutely love your videos! Look forward to them every week. But you make it look so easy!

[@CH3825]

Woo hoo, a new Hackaweek video!

[@shmittieschannel]

Love these videos, have been watching for a long time. I am currently rebuilding a 1975 Honda CB 750 super sport engine. These videos help so much! Thanks!

[@johnbeardsley7360]

cant believe all the detail,very informative,learning a lot.thank you for sharing,john

[@SeanBZA]

I was wincing at you starting it dry, without even bleeding the system by loosening the oil filter till gravity fed oil into there to get some of the air out. Hopefully there was enough assembly lube in there to keep the bearings safe, though you could hear from the starter sound when the engine finally got the main gallery's full and oil up to the crank and cam.

[@DeanSegovis]

SeanBZA Not dry, PLENTY of assembly lube on everything so no worries. :)

[@efleschner]

Loved this week's intro!

[@maxcorpious]

That is awesome! Good job. I'm still disassembling my '78 Yamaha XS750 engine but I'm anxious about getting it back together and doing these test myself.

[@FJ55ironpig]

You are getting so close to the much anticipated vroom vroom time

[@ManFAC3]

I gave a "thumbs up" immediately after the intro.

[@wojtexs6509]

You are the greatest! Thanks for all Your tips!

[@skycarl]

Just excellent Dino. What a great job you are doing on this. Kudos m8. Thanks Carl

[@HonorNecris]

On my '77 750K engine there were aluminum crush style washers inside the fittings that go to the oil tank. I thought they were part of the fitting at first but then they popped out.

[@Graabein1]

Man I just love this build :) Thank you Dino :)

[@radkusp9479]

Świetne są Twoje opowieści i relację - tak trzymaj. Pozdrawiam

[@Ozplatelickerscovidcon]

you’re gold mate,

[@realestaterider]

How long did it take for the oil to pressurize? great video i did it today but no oil flow?

[@H3adcrash]

Hahaha! I love the intro! :D

[@CraftwerksMC]

Nice touch on the hipster slam...

[@themistoklesv]

That red fairing in the picture behind you looks great... if you get my drift

[@M00SEM0T0]

Thanks for naming your cat after me

[@troycrowder9942]

thanks for that video i didn't know were that oil tank line went that went to the back of the crank got it on now

[@timgremour917]

awesome video first one i watched will be watching all your videos on honda 750 4

[@BrinToo]

Great milestone, nice work!

[@Sig220Euro]

Great to see the beast making it's first turns. Watch the coffee, might need to cut back on the additive in it...

[@jean-lucgros4421]

I'm very interesting about your video.I restore the same and I wait for the next : Thank you for your advice

[@Dirtyimprezawrx]

Did you ever make a DVD of the build? Cause that would probably help me out easier than having to constantly look at KZbin when I reassemble my cb750

[@ibrahimbawi]

I just finished and sync the carbs on my cb750. Let me know if you have any questions.

[@kd1s]

Interesting - you can tell there's oil getting in by the sound of the starter. It seems less strained when the oil is flowing through the engine.

[@Mekhanic1]

That's because the engine was dry (eeeekk). Once the oil primed, the friction went down. I would not recommend doing what he did. You should fill the filter housing with oil and also pour some oil onto the cam, lifters, and into the cylinders with the plugs removed. etc.

[@DeanSegovis]

Mekhanic1 Lots of assembly lube on everything so no worries. There was also light machine oil in the cylinders. I've built up dozens of engines over the years and I've done this same procedure many times with no problems. :)

[@kd1s]

***** Yes indeed. It's been very enlightening watching as you rebuilt the engine on this bike. Thank you!

[@Mekhanic1]

***** Thanks for posting the videos nevertheless they are great!! ;)

[@novachannel1981]

Loved the intro and loved the video as always thanks I'm excited to see it run to haha

[@nickkerr9392]

Nice work Mate. All the pre fit tests you're doing will save you pulling the engine out after it's in the frame if it's not right. Interested to see how you do fit the motor. Easy to lay the frame over when it's in pieces but a b@stard on a complete bike. With your skills I suggest you invent and patent the Honda 750-4 engine stand / hoist so you can ease the engine out with it on the centre stand.

[@DeanSegovis]

Nick Kerr Workin on it!

[@williamtraveler5449]

Best intro ever!

[@muh1h1]

can't wait to see this motor running at some point :)

[@aaronmarkstaller]

Where did you get that poster in the background? That was test week where we all rode stock bikes on the flats the year before we finished the streamliner and went back to try to break the record

[@realestaterider]

Where did you connect the Positive Cable on the engine? Great Vids really appreciate them.

[@38721078]

I want to know too

[@dancemoves2010]

Dean, your videos are very informative, I have been using them while I rebuild my CB750 as well. I was wondering how you plumbed in that oil pressure gauge. I am guessing that the thread on the engine casing is some sort of metric form of tapered NPT thread.

[@alexakkers2859]

Awsome collection of videos!

[@fcfarao22]

When we have the right tools to do the job!Quando nós temos as ferramentas certas para fazer o serviço.

[@TheHawkTheHawk]

Hey Dean?! You've actually inspired me to build a cafe racer on my 81 cb650 instead of a hardtail bobber. (Living in Mn a hardtail wouldn't go that well lol) love your vids! I enjoy watching, listening and learning. Quick question. Are you into the bobber style? If so, would you consider making one? Like from a Honda cb???

[@chriss8354]

Hi, is there a custom tank online that you can replace the OEM oil tank with? Trying to free up that triangle on my 77' CB750

[@Slow.Learner.Devolution]

I like the way ya think! Great into.

[@crispinleslie]

I'm getting withdrawal symptoms; this is worse than waiting for Breaking Bad!

[@ichi1977]

Great vid....the introduction killed me whaa

[@braddazulma5993]

Where is the positive cable connected?, I m trying to do the same thing but mine will not crank

[@utahbones3094]

Looking good!

[@robertdees2179]

What year is this motor ? I am working on a 1978 cb750

[@trentmcinturff4148]

The first time I saw this I nearly fell out of my chair I was laughing so hard. "Bullshit hipster bike video"

[@wald01979]

Silly question. Is there a concern about when convention motor oil and causing clutch slippage (I assume a CB750 is a wet clutch)?

[@duggus4992]

What happened to episode 23? Great intro by the way!

[@duggus4992]

found it ha

[@jeffbecker7703]

Regarding the oil filter - Just curious why someone would include a used oil filter with this since you mentioned that the engine was torn down. Had the seller already cleaned it or did you get a dirty oil filter in a plastic Wal-Mart bag?

[@DeanSegovis]

Jeff Becker It was still in the oil filter housing. There are two of a lot of things for this bike. That oil filter housing was very clean and painted so I used it. The filter was in another housing that was painted black.

[@johnthomas1281]

Hello, I am just wondering how similar to the cb900 custom this engine is

[@panionleadman1607]

great videos! a lot of good info

[@bwtegu7135]

Will this build series be pretty similar to a 1975 cb550, i just picked it up and have been watching tons of your videos in effort to gain some knowledge for a rebuild

[@HackaweekTV]

It should

[@bwtegu7135]

Awesome, thank you so much for all the amazing videos they’ve helped so much in my cafe build!

[@MackieBass]

"Bullshit hipster bike video... Far from it!" - Awesome dude!!

[@llewvirtue861]

Always use a touch of rubber grease on O rings

[@shortaybrown]

Hey Hackaweek, nice vid. You're totally Famous! Everybody was talking about you on the last RNickey Mouse comments. What do you think of that channel?? Do you like it? Do you ever think you'll go drive thru that canyon??

[@luisvelarde8999]

I’ve seen these series of videos several times. How long did you’ ve been cranking the engine until you got that first 6psi? I am now running into a same situation and had to charge the bike’s battery several times and still no pressure.

[@HackaweekTV]

It can take a while to get the pump to fully prime and pump oil.

[@gasousman]

C'mon number 23!

[@albertoalfaro82]

Did you recommend cancel the oil cooler ?

[@Logjam5]

Shamus likes the grub.

[@VattenDemonen]

Nice work love those vids I allso love the vids on the saber bike :P

[@johnacosta8529]

Can we move the oil pan to be horizontal against the front bar it’s in so that there’s a clear triangle on the bike?

[@HackaweekTV]

I guess so but why?

[@surfer_ann]

you are great.

[@robertbrandywine]

Why the oil reservoir? Is this what they call a dry sump engine?

[@stephenphilips8024]

Yes.

[@AbdulHisyam]

_ok i`m here for shemus_

[@jonaspetzall]

lovely! passing the engine build were approching stuff i'd be able to do myself :) oh and btw, afthole lol. For the young kids huh?

[@ZukaDon]

Awesome!!

[@BillAndersonNS]

[@MrTMJ110]

Best intro :D

[@mrbiston1]

very good

[@mbehning1]

Im thinking of rebuilding the top end of my cb550 this winter. Is it difficult to do with the engine mounted to the bike or will I need to remove it ?

[@hughtuller6344]

You will need to remove it.

[@PPG9944]

That intro just got me hahahahahaha

[@mjgl1903]

ehhh ¡¡¡¡ were is the 23 parts ??????

[@oslec1965]

where's the vid part 23?

[@HackaweekTV]

oslec1965 It to be done. Taking a break for a few weeks.

[@truantray]

Anyone know the difference between a flanged bolt and a bolt with washer?

[@DeanSegovis]

truantray Maybe the way it handles heat and expansion/contraction. It's odd.

[@rogovicbranko]

I am at this point with my build. The oil tank is filled and I cranked it for about a minute, and no oil coming to the top... Any suggestions? I'm afraid to keep the motor cranking even though I used assembly lube on everything you have so far. The oil level hasn't changed either. I'm thinking I have an air lock and need to loosen up the filter and see if oil is getting to the crank case. Please let me know what your thoughts are when you get a chance. Thanks

[@hughtuller6344]

Branko Rogovic I'm having the same issue. Did you figure it out?

[@SteveMyBell]

I'm having the same issue...

[@buchananjames8724]

I like that cat

Please don't tell me your cat got filmed by accident... Like the other one last time at the end of the episode ;-)
