- CX500 Rescue PT2 - Carburetor Cleaning and Vacuum Sync! The CX500 is running much better after a carburetor cleaning and vacuum sync which I gave an intro to in the previous video. This shows a good A/B test on doing a bench sync vs a vacuum sync on your carburetors. A bench sync will get you pretty close but as you see its not perfect. Overall I was within a half turn of the adjustment to be truly equal.

For my ultrasonic cleaner I use a simple green pro HD currently. This was recommended by another shop owner who does a lot of aluminum parts. So far it seems to work well. amzn.to/3R0b5i3
- 30l Ultrasonic cleaner
- 5 gallons hot water
- half gallon simple green
- A few squirts of dawn dish soap
- 35-60 degrees Celsius depending on what i'm doing. Hotter temps remove paint so use caution.

I have to say: I really love the color combinations on this bike. It's unique and 'different', but at the same time it looks as it could have been the original colors 😁
Many thanks! Spent some time on it for sure
me too, might steal it for my Triumph Scrambler
Yep, that is a good looking and great sounding bike! Excellent video as always! I do enjoy watching you work, man! Keep it up! 🍻🤘💜
Thanks Andy!
Really enjoy this content. I love seeing the bikes I grew up around being brought ALL the way back to life. It shows that you love what you do!
Well thank you much!
Got my $100 cx500 running 2 days ago. Carbs jets were mixed. Running so good I'm gonna keep it and build it up
Awesome! Mixing those jets is an easy mistake to make
Wow!! This is awesome, thanks for sharing this and all the details. I think I mentioned elsewhere that you are living the dream !!
I have a 1980 CX500C (as well as a couple of GL500's, a '79 CX500, and an '83 GL650, all project bikes. In the next couple of weeks I'll be balancing the CX500C carbs, as it runs but not smoothly - all stock. If needs be, I will take the carbs out and strip down/clean etc.
Many thanks again for this!! (As well as your other video's!!), Cheers, Adrian 😀👋
Thanks Adrian!
I really appreciate you taking the time out to get back to me on my questions I had for you the other day. I am now on the hunt for that Honda Hawk. You had me at single rear swing are. I had forgotten being stuck in my builds being limited to the meat that will fit between the rear swing arm. Plus a single rear swing arm is just cool man. I think this channel is the Cats Pajama's. I love to see craftsman do incredible things not with a shop full of the newest and greatest but with brain power, blood sweat and tears. Just Subbed!
Well thank you much!
Great looking bike. Learn something every video. That is one comfortable looking seat on that bike!
Thank ya! Definitely comfy!
Another nice, informative video! Great sound from the exhaust and induction noise as well. Unique looking bike - looks good.
Many thanks!
Very cool video on carb overhaul and in-general freshening of this bike! Sounds like it runs well to me!
Tuning CV carbs with individual air cleaners can be a PITA, but, if the carb is understood, it's not that bad. I did it with my CBX a long time ago and picked up a ton of power. Trick is to get the vacuum slides to open smoother but not necessarily quicker. I did that with a spare set of slide springs, kept tying up a coil until I got them right, and opened up the vacuum bleed in the spare set of slides I had to make that work even better. Lot of work, keep a standard airbox if possible!
Thanks man!
100%. It would be a long video going over tuning theory with cv carbs but again I feel I'm no expert.
@@BrickHouseBuilds you did just fine, man! Keep up the cool videos!
I feel ya, my first cafe bike was a CB 500 four. Its was free, laying in the bushes outside. The carbs were full of junk, after cleaning I made 300 attempts at syncing them. I was in way over my head.
Alway nice to hear a good running bike.
Agreed
Lovely watching this - I had one for a few years in the early 1980's. It was eventually stolen and never seen again. I quit riding at that point as I had had a few close shaves prior to the theft. Still miss the bike though - Sigh! BTW your bike sounds incredible.
Glad you enjoyed!
Hi BJ
I just wanted to thank you for all your UA-cam content in general and this one in particular. I always watch the full content of your videos as often the nuggets of advice reveal themselves. In this video the explanation of cheap pod filters helped me resolve a massive problem I was having with my 1977 CB 550F2 super sport. I wrongly assumed that I was having a lean out around 4000rpm and a rough idle that I couldn't sort in spite of rejetting. After watching your video I realised that the cheap pod filters were totally blocking the air jet passages and causing a rich situation. I swopped them for 4 foam filters and the transformation is unreal. Cheers fella keep em coming!
Best
Bruce
Yorkshire, England.
Great to hear Bruce! So so many people fight poor quality pod filters and end up giving up. Its very much worth spending a bit more up front and getting the right thing. Glad you sorted it out!
I like the color and paint plus is not too loud which makes it even cooler!
It has a great noise level. Didn't want it to be too loud either so mission accomplished!
Thank you for the ultrasonic mixture details! Something I've been looking for :) ❤
Thanks dude
I have 3 weeks off between jobs in October, and a GL500 sitting in the shed that needs a carb overhaul, so this was perfectly timed, thanks!
Sounds like you will have plenty of time for some riding!
@@BrickHouseBuilds If I can get it road-worthy :]
Sounds fantastic. I'm totally with you. Fun, way over fast.
Agreed. I love fast as well but fun is the first goal
This thing looks like a lot of fun. It would be full street tires for me, but it does look good with that setup. Nice work.
ETA: spray paint finish is great. If you want to spend a thousand hours on it that's cool, but it's also cool if you want to get it done and go riding. You do you.
A lot of times done is better than perfect. The white cx took like 3 years lol
I always found my CX 500 to just be fun to ride. The center of gracity is a bit too high, but still manageable. I just felt comfortable on it compared to my many other bikes. I'm too old to ride anymore, and after that stroke I had to get rid of my stable of bikes so the CX-500, and the K0 CL-350 is all that is left. Thanks for the video, and letting me ride with you.
Glad you enjoyed Dave!
The engine and exhaust note is sweet. Well done.
Thanks James!
Great looking bike! Love the colors….
Thank you much!
Very nice film Thanks allot love this old Hondas 👍👍
Glad you enjoyed!
I am not knocking your work in any way but I must say painting carbs is nothing that I have ever considered. Nice job on the intricacies of those carbs. My 1980 CB650C had the anti pop valves and all my experts said "don't touch them" as they were unobtanium at the time. Those were regular slides. CVs can be very tricky. Sounds great. You do nice work, sir.
Many thanks!
Carb balancing tests your patience for sure. I always find when I'm happy walk away, have a break and come back half hour later then re check. If your happy again then it's done.
Absolutely. Some bikes have definitely tested my patience!
Beautiful bike
Thank ya Brian!
Very useful as always and fun to watch too, thanks for the video looking forward to your next project.
Thanks much!
Looks awesome
Thank you!
I have used Cerakote, done at home (bought a cheap oven to go in the garage). Not used it on any carb parts. But like it for brake calipers, fairing brackets, clip on bars, etc where the thin finish and the resistance to brake fluid, etc, is useful. Takes time though and easier to mess up that paint (too thick a coating will blister when baked).
Doubt you would manage a good match to the rest of the paint using Cerakote though.
100% agree that fun is the important bit. I have bikes from a YSR50 gag bike up to a tuned 1200 Bandit (mostly have 125 2 strokes though), and fun is the important bit.
Im definitely still interested in trying the stuff though. I like the quality of it
Love these two videos. Just what I needed! Did I miss what you were doing with petroleum jelly-is that what it was?
I was just using it as a lubricant
What a bike !!!!
Thank ya!
Very cool looking bike, great colours
Thanks Jim
Every time I hear a slight clutch slip on your opening video I wanna pull my hair out 😂.
Sorry for ruining your viewing experience.
@@BrickHouseBuilds 😂
I do like the colour combination, very cool.
Thanks Brian
Man I just dig this channel!👏
🤘🤘
I don't know if you did them in the first build but in all the older bikes I worked on I always split the carbs and replaced the o-rings on the fuel and accelerator tubes between them. Nothing more frustrating rebuilding carbs and they seep out those joints when you put gas through them. I always bench tested the carbs also just to see if they have a leak before putting the effort to mount them on the bike.
The video just before this one is where I work on the carbs actually. Pretty good video as I go over some previous mistakes I made
That scrambler has a great sound to it and it runs much better after doing the valve, cam chain, and carb cleaning, sync and adjustments to it. Did you change the plugs? Great job once again.
Ran great for sure. No need to change the plugs though
Awesome vid
Thank you!
Always great knowledge, thanks BJ
🤘
Nice job, bike looks lovely. Its a lovely bike for twisty back roads doing 40/50mph. Why in all this cx500 engines there's a backround soun like a pulley turning or whispering lol . I can hear it in your's too. Thanks for the video . Gus
Thanks Gus! It just has a gear whine sound to it like some bikes do
Glad you had fun riding this amazing looking and sounding bike. I had fun watching the video.
I wonder why Honda quit making these transverse twins with shaft drives.
Well they still do actually in a similar layout. The st1100 and st1300 are V4 transverse mount with shaft drive
@@BrickHouseBuilds thanks for diluting my ignorance.
very helpful vid
Glad you found it helpful
I just found your channel, good stuff.
I’m pretty sure Ian McColllum over on Forgotten Weapons is your doppelgänger,
Well now I have to go see who that is lol. Glad you found your way here!
Riding with no gloves may lead to some damage. I still have the scars in the palm of my right hand...42 years ago I learned that the hard way...don't ride without gloves even for the around the block ride.
Hopefully the lack of gloves for a moment didn't take away from what the video was actually about
that sounds so good. I can only imagine it sounds better in person ...... I have the same carbs on CM400 ...I would love to see how you do the Idle drop for mixture screws. I have my CM at 3 turns out and all with the stock air box. I know I am off but I just can't hear a difference when setting the screw mixture.
CM400s are very fun bikes. I know ill have to make that video at some point for sure
Sorry for the off subject question but I really like the tires. What brand are they?
No worries. They are Bridgestone tw39/40 or something similar. Check the overview video in the description as I may link them there
After all these years, I don’t know how I missed dropping in a bit of dish soap to my ultrasonic mix, lol. 🤦🏻♂️ Definitely trying that today. How long do you usually run your parts in the cleaner?
All parts are different. Some stuff 5 minutes, some multiple 10 minute rounds. In short, as long as they need.
Hello BJ, I enjoyed the video, thank you. Do you find you have to ultrasonic clean the carb parts again after the soda blasting?
I have found that an etch-primer provides a good key for painting alloy surfaces.
Honestly, I thought the bike sounded really sweet when the work was completed, a cracking job. Keep the videos coming!
Cheers Kevin.
P.S. (I am a little troubled by the wiring into your ultrasonic cleaner!) take care.
Yes I always run them in the tank after soda blasting to dissolve the media
I notice you don't seem to worry too much about mixing parts from the left/right carbs whereas I've seen others be very particular about it but never understood why. If the parts are good it shouldn't matter what they go back into.just wondered what your thought process is?
Also see you use petroleum jelly...is that just for the rubbers?
I try not to mix slides but don't really care about mixing brass around. Some have said it's best to avoid but I see the pros mix parts so I'm not worried. Yes, petroleum jelly. Yes the world will in fact end because I used it. Never had an issue.
hello good afternoon can I ask you a question I have BMW k1200s when I have to do the valve adjustment it has 87000km I have it 2 years greetings ok 👌👍
I have no idea. You will have to do your own research there
For the average shadetree mechanic, with no ultrasonic, i am guessing a rebuild / jet / needle seat kit , if available, would be your recommendation ?
You could buy some lemon pinsol and soak them overnight then cycle carb cleaner and compressed air. Much more scrubbing required.
Sounds amazing! What muffler do you have on the bike?
Thank you. The linked video goes over the build details with helpful links ua-cam.com/video/5otPyE4lk_g/v-deo.html
@@BrickHouseBuilds Thank you - brilliant build mate.
I am getting ready to purchase a 1981 cx 500 touring. Anything I should look for what the bike? Any upgrades that make this bikes a lot better ?
@vinnyresinger4809 there are some good articles on motofaction.org like buyers guide that will be helpful. I think digital temp gauges are nice but making them better depends on what you want to make them better at
I just replace pilot jets...too risky to reuse..hard to verify clean enuff.
With carbs the details count super big!!
I like to just clean and know that I have a factory stamped jet
hi, how's the goin'? what kind of tape do you use to protect the parts you do not want to be painted? I used regular masking tape, but the paint always finds a way to sip in under some parts of it. any tips on that?
Mainly plain masking tape. Decent quality goes a long way
Have you done anything with the front brake to improve things? Cos my deluxe with single disc is awful. My mtb has better brakes, lol.
It has a stainless line and seems fine for what it needs to do.
Hey BJ, do you use full strength muriatic acid? Side note, your pink respirator cartridges are good for dust particles. Better than nothing but for any kind of organics (paint, chemicals etc) swap them with the plastic cased cartridges.
Full strength. I know the cartridges are different but I just don't take the time to swap every 5 minutes for various stuff I do. Again, usually outside and up wind of the stuff.
@@BrickHouseBuilds fair enough
Hiya,my missus has a modified gl500 ,ive balanced the carbs but it does have thoose restricted type pod filters on because there is limited space,do you have the spec and size for those filters you use without the restriction 🙂
A UNI PK92, K&N, DNA, or dynoman filter will work. Check my first start/first ride video for my gl650 build. I have a link to the k&n filters
Hi, I'm driving the GL 500, 1982. I would like to know how your idle speed is. I think, my motor has 1100, is that ok?
This bike has no tach so simply going by ear.
Hey
Hola
yesterday I read the specs on the 650, wich said it has less fuel consumption than the 500, how crazy is that??
Well the 650 had a different gearing which meant lower rpm on the highway
@@BrickHouseBuilds Ah I thought it has to be something like that! I think the 500 is going to perfect for me, I need a relaxing bike besides my SV650 gen1
Am I too early/late to ask.... Is this bike going to be for sale? If not... Could someone commission you to build another one similar? Awesome shaft drive rock/roller to hit the trails with. Great job.
No this was built for a customer back in 2016. I no longer take on commissions as of 2022. Just personal builds and parts sales/tech support
You didn't put your ultrasonic mix in the description. Looks like that different color simple green though.
Yeah I need to add that. I will soon
updated
Am I mistaken or does the hose going from the fuel tank to the carb say “not for fuel” 😂
Not for fuel injection. Low pressure only
hey man i have a 1981 honda cx500 and i was wondering if u could help me i have a small issue 👌and thats the gas is mixing with the oil do u know what it could be or multiple things i would really help alot thanks in advance 😄
Water pump mechanical seal likely
Could check the float valve, and pet/cock seals.
what other fuel tanks fit the cx500
That honestly depends on your fabrication abilities. Nothing will be bolt on by any stretch
Hi BJ, hope you are well. I think you've raised your game since building this bike originally, except for riding in wet mud!! Still, I think you enjoy the cleaning process, especially the results. Have you checked out Allen Millyards work? (He of the Viper powered bike!). ua-cam.com/video/FnXUx4cYdHA/v-deo.html . Thanks for sharing, Stay safe and keep up the good work.👍
I never miss an Alan Millyard video. He is very inspiring
how easy is it to change the gearing n bikes like these ( either higher or lower ) ?
You can't unless you have complete custom transmission gears machined
@@BrickHouseBuilds is it safe to assume the transmission ratios and the final drive ratios are all the same with this particular style of honda motor ?
@@charlesboston1 they are bike specific. The final drives and stuff rarely fit different bikes
