- Honda CBX Cylinder Head Disassembly - Found More Problems! I have finally made some time to work on the CBX restoration and continue with full engine disassembly after a long break. In this video I disassemble the cylinder head and address more issue with it. I remove a broken cam cap retainer bolt, find an issue with an exhaust guide, form plans for stripped threads, and file some damaged spots near the spring buckets. Next up is getting the engine components over to be vapor blasted before reassembly.

Fixing old stuff is what 'sustainability' is all about.
Bought my Honda 305 Dream at a JY for $150, spent a few hundred cleaning it up, was my daily rider/commuter for four years, still use it to run errands -- too much fun! Old Hondas are forever bikes.
Little victories, sorry I'm hooked on the cbx . I enjoy all your content, but I feeling like I'm involved in it. I really, really want to see that thing flying down the road. I understand you gotta make the payments. I'll be watching. Congratulations on your expansion. Best of luck in the future.
I appreciate it. When this is up and running I'll make tons of content on it
I’ve watched one other CBX rebuild, and I hope nothing ever happens to mine. Still fun to watch. With prices for CBXs these days, worth every penny to rebuild them.
Yea its a large time and financial investment to say the least
I'll second that i have a bit invested in my 79 project
I really enjoy your repair videos and the attitude you bring to your work. Wonderful. Rescuing old stuff is where it's at for me. Anyone can throw something away and bolt on a new one. There's no skill or invention in that. Thanks very much for these videos.
Thank you. I definitely want to revive and not replace as much as possible. We will see how much of that I can do
Ha ha... That smile at 09:41 when you realised the stud was coming out... Classic!
As I said I expected the worst but hoped for the best. Was very surprised how easy it came out
I see what you did there...how "easy" it came "out" 😀
Excellent video and gorgeous music to boot. Great result getting that broken bolt out first time and what a perfect example of how to use an easy-out extractor. Nice one…👏👏👏
Thanks John!
Yes quite true, this bike and it’s engine is in very capable hands. Looking forward to the next installment of this build.
I worked for Honda from ‘76 to ‘78 bending wrenches at a Honda dealer in Marysville Ca until I enlisted. My boss was a Honda Works mechanic in the ‘60s - Jim Capps. He was the real deal master mechanic, magic engineer guru, and ultimate mentor, teacher, and friend. You seem to be a lot like him.
Well he sounds like a swell guy!
As a previous CBX owner, who wouldn't have dared do anything like this.............this is sooooo satisfying to watch!!
Glad you are enjoying the series. I hope to get going on it again and have the engine finished this winter
A good mechanic in action is like art
Good Job
Thank you much!
Hi and thanks for your videos and excellent standard of workmanship. Just a tip with that broken bolt: i would have put a close fitting drill down through the dowel to get a good centre mark to then drill for the easy out; because, as you would know, getting the drill hole central is imperative, especially if it comes to drilling the bolt out completely. :) cheers, Neil
Noted
Great execution on that stud extraction. Took your time drilling, maintained the bit center as needed, etc.
I thought the Buell had a ham fisted PO. Backward valve guide takes the cake.
Yeah that was a crazy find!
Another vote for an update video. Great work!
Im worried an update video would only upset people as they would see it as a waste of time. Really torn on what to do as I mention the cbx status in nearly every one of my videos now.
Sheeeeesh man whoever the previous savage was that neglected this treasure needs a good “talkin to” 😂
Somebodies ManCard needs revoked and replaced with a KarenPatch . . .
Found the guy ☝️
Great job getting the Broken stud out !!!👍these can be so awkward to do 💥👍
Yea I got lucky this time for sure
Evening Buddy. That was really interesting and fantastic getting that snapped bolt out 👍🏻 I’m
now 66 and was brought up in the 70s on Honda CB motorcycles stating with a club 50 then a CB 175 electric start lol 😆 Then a CB 250 super dream old and new then a CB 650 tourer. Then a couple of K Hondas 550/ 750. And a few others. I then got a Honda super bike the VF 750 and came off at 110 mph. I’ve never been on a bike since but I do like watching guys like you restore the old Hondas that I loved 😍 I can remember dreaming about the CBX in the showrooms along with the Suzuki 750 kettles lol 😆 I had lots of other bikes from the era like KH Kawasakis Yamahas ect. but Hondas was my favourite by far. Cheers Stevie 🏴
Thanks! Luckily it came out easy and didn't require anything fancy
informative, interesting, your voice is clear and easy to understand. knowledgeable, good subject (even if you are not a motorbike enthusiast ) So ten out of ten. You need a new cap, though!
Well thank you much! For hats I have a revolving selection of 10 or so at all times
@@BrickHouseBuilds that would make my head spin!
It's videos like this that really make me appreciate my single cylinder😅
Hahaha 100%
You are doing a great job and great videos! For broken studs or screws I love left hand drill bits. It doesn't change anything from your method EXCEPT very often the broken part start getting out BEFORE you end the drilling. Even if it doesn't... it makes nothing different. And as I got a small lathe, I can make a custom drilling guide every time I need ... and it makes the drilling much easier!
I hadn't thought about that drilling guide! Thats a good idea
I concur with the reverse twist (left hand) drill bits. Often backs out the broken part during drilling.
Glad to see some more CBX stuff.
Same here lol
Whew, x24 what a mission .great job brother
Thank ya
As a former CBX owner I'm glad to see someone taking the time and money to return one to its former glory. IMO these bikes were under-rated and un-appreciated.
Its strange the mixed opinions on these bikes. For the most part they are now highly revered and appreciated but back then they didn't sell.
@@BrickHouseBuilds I bought my '82 CBX new in '83 at a heavily discounted rate - it had sat in the showroom for a year unsold. Many were donated to training schools to practice on. They were heavy and intimidating - and FAST. If you look on Jay Leno's wall, there is a nice video of his that he bought new.
Thanks for the video. I had 1980 and put a lot of kms on it. An icon for sure. Good luck 🍀
Thanks Mark! I appreciate you watching
You were very lucky with the broken stud, nice..
That I was!
smart gearhead. I feel refreshed, thanks.
Glad it had that effect
Great job with the easy out! I am always amazed when a repair comes out well! Regards from Canada 🇨🇦
Thanks Keith, I definitely got lucky on that one but Ill take it lol
Very good stuff....and yea, you deserve a pat on the back. Hats off to you.
🤘🤘
Hey man ! Just found the page and dug through your progress on the CBX. I am currently rebuilding my fathers cbx that he has held on to for the last 40 years. Would love to chat and share information along the process. I have learned the more people involved the more fun and better the process goes. Happy building !
Doing great work and doing it properly. Great to see & thanks for sharing
I appreciate it Pete!
Hi, great series, looking forward to the next episode.
A tip for marking the centres of the bolts where you have a guide dowel or a deep recess.
Use a transfer punch, a properly hardened one unfortunately not HF as they are to soft, sized for the inside of the dowel and get some left handed carbide spade bits.
Experience has shown me that sometimes you need to heat the immediate area with a small tipped oxy/acetylene torch to get as small a heat spot as possible so you don’t anneal the aluminium in the area to much.
Keeping the wood and self tapping screw count to a minimum is always a challenge.
Take care.
Did not need any of that here but thank you for the info
@@BrickHouseBuilds Thanks, had quite a few with various non standard fasteners to rectify in my past., prefer timeserts over helicoils but either work well.
Where's the CBX engine rebuild continuation . . . I was enjoying the quality you were bringing to that fab bike engine!
Thanks James. Due to business changes and customer bikes getting delayed the CBX got pushed down the priority list. My plan is to complete the engine this winter though. I am getting very close to starting on it again thankfully.
@@BrickHouseBuilds Oh, that's cool to know. Thanks for telling me! You do really fine, careful, patient work that's very interesting to watch, particularly on this classic Honda CBX engine.
He, where are ya with the build on this CBX now? Loved watching this tear down and forensic look at the inside. Nice stud extraction on that cam cap stud. Having worked on Fiat’s of that era I became accustomed to that stud removal process regularly. Grinding on aluminum is also a bitch with the wrong appliance huh? Carbide burr bits were such a blessing when they first came out. I’m hoping you still have it 😮
Hey Stewart I've talked about the cbx in many videos trying to keep everyone updated. I have so much going on. Check out my "thank you 2022" video for an update. Or my latest benelli video, or the parts storage video
@@BrickHouseBuilds Thanks for the update. I really have started to go back and watch all the older videos so I'm kind of catching up :)
Geez, that engine has been properly stuffed up. Throughout the series I shook my head at the previous jobs done.
Hope to see the continuation of this project in the future. But I can imagine it being a costly project as well as time consuming.
Yeah it's been a constant stream of poor work. I hope to get back on it soon with my new space as I need a ton of room for this project.
yes, i enjoyed the video BHB. Thanks
Thank you, glad you enjoyed
Well done, touch and go there ,i nearly called it . keep up with the good work ,
Thanks Keith
Love from Pakistan brother
🙏🙏
Just get a left hand drill bit if it catches the bolt comes out ever so nicely!!!
I dunno... just love watching your videos... hope you Ride it!
Once completed I'll definitely put a couple thousand miles on it
Brazilian Honda CBR 1000f 1990
Really enjoying this series, is there an episode 6 yet?
There will be. Please check out my "thank you 2022" video as I talk about project timelines
@@BrickHouseBuilds 👍👍
Good videos, i'm a fan of CBX
Excellent work :) cant wait for another CBX video ;)
Hopefully much sooner this time
Look at it this way. The more thing's you find wrong, the more videos you can make, an the more videos you your followers can watch , an learn how a PRO does thing's !!!
The way this is going I will have endless videos lol
I haven’t been subbed for long enough to know if you someone else edits your videos, but the editing in this one was really good.
Thanks Mike! All me and I appreciate the compliment
Awesome skills
Thanks Craig
Another great video. You had all the luck with that broken stud. What is going to happen with the broken metal that shouldered the camchain that fell into the gearbox? Are you going to weld a new piece on, or just chamfer it off. Keep up the exvellent work.
Im not convinced that this is the same head that it had originally. I can't find any areas with broken off bits so I think the piece I found was from the original head.
Great job !
Thanks Philip!
Such big cost involved personally I’d mic each valve look at the faces and margins under a magnifying glass and check run out no point junking good parts looking forward to seeing this head all vapour honed. Seats cut etc r u going to leave the head in it original aluminium finish. Nice job on the bolt removal the bottom cam brgs look great how r the cap brgs luv the cbx is it a faithful restore or resto mod
Ill have the machine shop do that but being that valve recession is a real thing on these its more of a "while im in there" I better make sure its right kind of thing. The engine will be painted in the original silver. I have a couple bearings that need a light polish
My motto when rebuilding engines, is that everything has to be better then new.
Can you raise the compression a little?
I could but its a restoration so all factory spec
Well done sir.
Thank ya
Nice one 👍
Thank ya
Time seems to always be the difficult part, great episode. Good job with the bolt, did you have to use heat at all?
No it came out real easy. Barely removed any time from the clips. Just some fast forwarding
Hell yeah brother. You ever consider a GS1100 Suzuki? You always have the coolest bikes around. Good stuff
Definitely thought about one. I'll be building my own version of a Katana this year from a gs550 frame that should be rad
@@BrickHouseBuilds Hell yeah looking forward to it. You're one of my fav channels! I've learned a lot about bikes through ya, so I appreciate that.
Loved this series... what became of the CBX?
It had to be put on the backburner unfortunately due to many life and business changes out of my controll. I talk about it in many videos like the most recent Benelli update, "thank you 2022", and even my new shop updates. I very much have been making plans for it and soon ill be in my new shop with room to tackle the project and take it to an even higher level. Very excited
@@BrickHouseBuilds Awesome!
How many drill bits did you use on that stud? Always use a lubricant when you’re drilling out any bolt.
1. As you see I got the job done
Top man.
Thanks Ray
Best investment you will ever make for removing broken bolts and studs .... left hand flute drill set. Act as easiouts as you drill... check em out.
You may know this they do make left hand drill bits, they will try to remove the stud as you drill. For bolts not in very tight they will remove the bolt so no need for the easy out ( not a joke).
Yeah one of those tools Ive never had to have I guess. I should still grab some but so far i've always been successful with traditional bits.
Cool videos - thanks.
I had a red 69 - loved it.
Does it really only have 11K on it?
Hopefully this one didn't have too much talking for you 😉
They didn't make a CBX in 69 so I assume you mean a different Honda. Maybe CB750?
That was a typo - it was a 79 - first year. The only mod I did was a 6-1 pipe.
Talking is getting better.
LOL
@@BrickHouseBuilds
A 6 into 1 definitely sounds the best. For this bike since it is going stock I must go 6/6. Check out the recent CBX revving video I posted a few weeks back. It was from Barber Vintage fest
No need to replace the valves, just regrind them!
That is what they do in the head shops, unless they are really worn out.
But these should be fine.
You don't regrind these actually. Due to their design they are notoriously soft and should be replaced
@@BrickHouseBuilds I am mostly a Diesel guy, so I don't know much about motorcycle engines. I did ride a 1996 CBR 1000F for 5 years.
Best bike I ever had......
Never had any problems with it, just put tires and gas in it.
I love that bike.
This video should give you a taste of it.
But you might already know it.
ua-cam.com/video/w38VuQNU_6I/v-deo.html
Awesome vid. I'm about to tear a CBX apart and do the same thing. One question, where did you get those small organizers behind you on the stool. Does seems like they would be so handy on a project like the head keeping all the various parts segregated
Thank you! All the little bins come from Harbor freight and wal mart
@@BrickHouseBuilds thanks. My shop is like yours, Immaculate and I can see that you and I both have the same illness of organization OCD. Already found those bins. Thanks again, will come in very handle during this CBX pull. Watching your vid game me inspiration, was dreading it a bit lol
Any idea when we can expect the next instalment?
Hey Roger, I got this question daily and have covered what the CBX status is in my recent "thank you 2022" video. Please check that out
@@BrickHouseBuilds yes, thanks, I found the video after I sent the mail, sorry to have made unnecessary work for you. I love the CBX, never was brave enough to get one, Honda tiny tears lol. Personally big Kwaks for me. I've had a Z1R and a GPZ900 but my favourite was the GPZ 1100 B2, you should try pick up one of those it's a monster of a bike, junk the EFi though and go old school carbs. Good luck with the CBX, can't wait to see it on the road
Where did you get your chain guides refurbished?
Bert from six Center
So when that bolt just started turning out so easily did anyone else think " You lucky shit!"
Well yea myself included lol
The more I practise, the luckier I get. That's as true for BHB as for anyone. A mistake lots of people make with screw extractors is to drill too big a hole in the broken bolt, assuming that a bigger extractor is bound to be better. But the bigger the hole, the less material is left and the broken bolt can be expanded by it to grip tighter. Still, I would have used heat too to be on the safe side. I've only broken one extractor - the first time I tried to do the job - and the pain of rectification means I go really really careful with them now and use them as the second to last resort. The last resort is to drill right out and retap for a a helicoil or timesert. I've given up with extractors when there's no sign of movement and a risk of snapping them to move on to that last resort.
What are cleaning the combustion chambers with?
I was just lightly scrubbing the loose stuff off with solvent
Hello. When is your next episode on this bike. Looking forward.
Hey Freddy I don't have a date for that. I talk about everything going on in my "thank you 2022" video along with my latest Benelli video. The cbx went to the back burner and there are many things going on that have prevented me from working on it
There is a CBX with like 20k miles selling for 32,000 dollars here in Seattle...
It is mint, but gaddam
Yea they are stupid expensive which is exactly the price I plan to list this for when done lol
@@BrickHouseBuilds Get it brutha 🙌🙌🤘🤘
Do you ever balance tires
Sometimes yes
@@BrickHouseBuilds Thanks for the reply, how do you do it. can you do it your self.
@@danielsherman8565 There are multiple ways. Id just search a video on here for various methods and techniques
@@BrickHouseBuilds Thanks.
replace the valve guides, I made that mistake and always got smoke
on start up
👍👍👍
You really need to invest in a little milling machine one day, make your life soo much easier,
I have a small lathe. Took me a long time to get. A mill would also be great but my biggest issue is my small workspace
Do you have merch? like Tshirts with your logo?
Currently I have hats and stickers until I can get more shirts and wearable stuff made.
@@BrickHouseBuilds Cool..where can I get that stuff?
Everything I offer is available on my website www.brickhousebuilds.com 🤘
Even though I understand you're busy, it's a shame this was the last CBX video a year ago now.
I have never seen an engine rebuild, but always been curious. Seeing this engine get the treatment you have given it, is an eye-opener. Have watched every CBX video in order that you have made. That sort of says something, that I am genuinely gripped by this.
FWIW I thought you would have done an engine rebuild on the CB750. Just for love and to make sure it's tuned 100%.
I'm kind of partial to the Kawasaki GT 750. They were built about 1980 - 1990, but almost all of the examples we see now are rough.
However I saw a vid of a mint GT 550, that was for sale. ua-cam.com/video/N0IVDwiAdFE/v-deo.html
Also someone riding and showing a nice loved one. ua-cam.com/video/GZ7Cx3fy2G8/v-deo.html
It is a shame its been a year. That was never the plan but I have not had the ability to see it through yet with all I have going on. For the CB750 it runs like a top with 165 PSI compression on all 4 cylinders, no oil usage, and clean oil filters so honestly no need. I also don't want to rebuild it as that means the bike would be off the road for a long time as evidence by this CBX rebuild lol
@@BrickHouseBuilds I remember in the CB750 hour long video that you said there was very low mileage on it. hence no need for an engine rebuild.
I don't have even 1% of the bike knowledge that you do, so I was not being contradictory to you.
More just watching for fun coz I love bikes. Like I am not specifically a fan of the CBX, but due to loving bikes, it's impossible to pass that video. The engine strip down was brilliant.
What's also cool is your appreciation of older bikes. Quite a few new bikes leave me cold, especially the ones without a proper pillion seat. Something that older bikes never got wrong. Many new bike pillion seats make me annoyed that they designed them looking uncomfortable. Whereas your Bandit seat is what bike seats should be like. Eyewatering bike.
Anyway, best of luck. Your Bandit is incredible. If I were a jealous type person, I would for sure be envious of that. As I am not a jealous person, it's nice just to know it exists and is in great hands. (Nice to have seen it.) The chromed side panels that you painted black, look excellent.
Shocked by how bad overall this engine is.. it must have smoked more than my bro.. with his cigars billowing out smoke.. cough cough splutter ... 👀😀those valve seats ???? WT?! 😗Good to see the valve compression tool you made up.. for newbies/novices.. bought tools can be mega expensive.. patent tools MAJOR expensive.. I'm inclined to agree with you re whoever worked on this before? 🙄NOT coming near any of my bikes.. EVER!
Thanks again Arthur. Just a not im not a newbie I am just frugal on stuff when I can make it myself.
@@BrickHouseBuilds Apologies, I added that in for Newbies et NOT applicable to you.. 👀It's surprising how many watch these vids.. which is always good if they're into motorbikes et I've been riding for over 40 years + and like you, good electrical / mechanical skills.. NOT just bikes but cars et Really enjoy your very professional skills.. 🙂Believe me over the years I've added a lot of tools to my collection that were 'hand made/machined et ' Having a mate with a 'milling machine' and skills was also a mega bonus.. 👍
Brother where are the follow up videos?😢
@whateverrrrrr123 a whooooooollle lot of life and business changes happened in this period and it's been hard to get back on the project. As I'm now finishing a custom build, the goal is to actually start up on this bike in the next month
I wonder if it was more than 1 person who buggered up that engine?
Not sure
Could be worse, could be me trying to fix it
🤣🤣🤣
A replacement head would be cheaper and quicker
Highly doubtful on that one. Have you priced CBX parts?
It should be silver
Yea I talk about that in the video
I know where it is and thinking about getting it back
👍🏻👍🏻👍🏻👍🏻👍🏻👏🏻👏🏻👏🏻👏🏻👏🏻⭐️⭐️⭐️⭐️⭐️⭐️✅✅✅✅✅
👍
bad cooling of cylinder 3 and 4
Ok
How the hell can an engine be in such terrible condition after only 11,000 miles?
Bad owners doing worse work
Beaten and poorly maintained. Not a good starting place.
At least I have a place to start. I'm not afraid of work
I loved old bikes but i wouldn't want one ever again
They definitely take a strong desire to maintain and repair them
@@BrickHouseBuilds I would maybe feel different if I was like you and had all the cool tools and knowledge. And if I made good money
💪❤
