- CB750 Oil Pressure Gauge Install And Oil Filter Inspection! In this video I install a very nice looking oil pressure gauge on my barn find CB750. I had a leaking oil galley cap oring and that's all the excuse I needed to buy a gauge kit as I like the idea of knowing what type of pressure this engine generates.
This is part of the ongoing revival of this bike after I got it running. I also cut the oil filter apart to do close inspection and look for any worrying contaminants as I put more miles on this bike and cycle the engine.

I've never heard of cutting apart my filter for inspection. Wish I'd watched this 2 days ago when I still had the old filter... but next time! Thanks for the lesson.
Its one of the best ways to see whats going on in there
I've been riding my '74 CB750 for about 17 years now (it's the favorite of five bikes I own) and I really enjoy watching you work on yours. Also, I've been riding bikes for about 54 years and always do my own maintenance. I started using aluminum foil to keep the pipe free of oil during changes many years ago. Until I watched your videos, I wasn't aware anyone else out there was doing that. I guess great minds do think alike. LOL Anyway, I really enjoy watching your channel.
Im glad this video was enjoyable. I think I picked that foil trick up about 5 years ago from a video actually
I’m really impressed with your methodology and care with your wrenching. You have an engineer’s eye.
Great video.
Well thank you!
Definitely can relate with the general bummer that sets in when the bike is lockdown due to crappy weather. Absolutely love analog gauges. Give me a nice dial readout with well-established increments.
Oh man I feel this winter will be tough for sure. Needle gauges ftw
Love the Rotella usage. I use it for my older bikes. Newer bikes get synthetic because that's what they came with. Not picky about brand. "Run what you like," indeed! It's oil. You're not running in MotoGP. It's more important that you change it regularly than which specific brand.
Agreed 100%. You must also consider the quality of oil being made when this bike was new. Basic old Rotella is miles ahead still
That oil pressure gauge really set off the "rugged" style of this bike! Super cool looking!!! Keep it up!!
Its just a cool little piece to have plus it allows me to actually see what this engine makes for pressure. I had always wondered.
"Yes Rotella, No I don't care what oil you run" Perfect. Nuff said :)
100% 🤘
Thank you for all your CB750 Videos, I have just brought a 1975 CB750 F Super sport originally in the USA (Vermont) I live in the UK. Your videos have been such a great help to me thank you very much.
Well thank you and I'm glad the videos have been helpful!
Hi Ed, I am a brit living in Canada, I have a 77 KZ1000 with only 26k kiloms on it. Just a bloody pain the weather here is crap for like 7/8 months a year. Oh how I would love to bring my bike back to UK. Enjoy your classic Honda mate.
Your videos are always so well filmed. You are detailed in your instructions and I always find them useful. My 76 says thank you.
I really appreciate that 🤘 Tell your 76 you're welcome 😊
Another great video! Good camera work and plenty of detail! The gauge looks very nice and suits the bike! Keep up the great work, man! 🍻🤘💜
Thanks Andy!
Another most excellent video from Brick House Builds. Just great!
Great video - would never have thought of fitting an aftermarket gauge like that - thanks as always for sharing!
Thank ya. I guess im learning that these gauges aren't as common of an upgrade as I thought. I guess ive just noticed them more.
Lovely bike good to see them old machines put back on the road and looked after .
👍👍
Love this bike! Great content! Awesome comment on your choice of oil !
Haha thank ya Rick!
Very nice!! an other clean and perfect comprobation!! thank you, man.
It definitely fits the look of the bike. Thank ya
Thank you for saving the old girl. I have two 1978 cb750 four super sport F3 models with consecutive serial numbers. I call them the twin sisters. And for anyone reading this there not for sale.
Nice trick with the AL foil over the header pipes 👍. I wish I’d been smarter back when I had my ‘85’ CB650SC changing my oil filter. I’d spray it down with brake clean afterwards, which worked, but in time the oil filter cover lost all its black paint… nbd though. Nice job, thanks 👍😎 .
Glad you learned a new trick with that foil. Definitely handy
Nice job! Well done! Regards from Canada 🇨🇦
Thanks Keith!
Hey buddy im in love with your 750four, great channel keep em comming👍🏻
Thank ya!
Excelent and good job, thanks for sharing.
Thank ya much 🤘
really really like the cb 750 if i am able to find one it will be my forever bike enough power and nothing electronic and plastic like that is the allure the cb has for me and i am sure many others honda really knocked it out of the park with this bike
They are iconic bikes for good reason!
Nice restoration. My frist bike was a Honda CB 350 2 cylinder, I think a 1973 model white and flake red colour. My dream was a CB 500, but I could not afford it.
Many good memories with that 350.
You've got a really nice channel going, I like it a lot...
Be safe on the roads!
Thank you! Glad you have been enjoying the videos
nice ride I still have mine 78 super sport. have mine for about 35 years about 2 years ago I replaced the primary chains and while I was in there replace the cam chain too. and the rattling went away it was driving me nuts. love that you have her stock
I need a super sport in my life. Great bikes
awesome bike, just had my last ride for the season today
Thank ya!
just ordered a oil press kit for my 71 thanks for the ebay link....
🤘🤘
Great video! The bike looks and sounds great. Thanks for explaining the casting flaw - it did kind of look like a leak. And the pressure gauge looks great. Not too distracting while riding, I hope!
Thank you! Definitely not distracting at all
My uncle has owned a 550four since I’ve been on this earth, I’m 49. So naturally I’ve loved them my whole life. Beautiful machine I want to own one one day.
Thats very cool! Maybe he will sell you his? Heirloom?
@@BrickHouseBuilds honestly tried to buy it more than once. But he doesn’t want to
Well if he ever does im sure you are first in line. Maybe show him this video and make sure he doesn't let his bike get to this point
@@BrickHouseBuilds man I’d love to get it and fix it up
Looks nice and healthy, BJ.
Agreed! The black face/chrome bezel was the perfect look
Good show thanks for the info
Thank ya!
Nice easy fix!
No lie I was excited when that specific oring let go lol
Cool trick with using aluminum foil over the pipes,way better than my plastic mat thingy
Its a nice tool to keep in the shop
Nice job using the Rotella, it will keep that engine clean! And it less expensive compared to reg motorcycle oil. Great job on the bike. That engine is just breaking in, it will last a long time. 😊
Thank ya, since I change oil often I just buy a lot of Rotella and keep it fresh.
Nice Job by all accounts these old engines r good for well over 100000 miles especially if u do regular oil and filter changes I’m very surprised it runs as well as it does given the engine was locked up very impressive I’ve nog seen that rotella engine oil here in NZ but I’m a motul convert anyhow as r my mechanic and racing buddies in Europe 300v for the win !!
Don't get me wrong if Motul, Mobile 1, Pakello approach me and want to send me stock I will happily accept 😊
Very savvy, and now safe to boot. Analog has ever been the finer point, because leering lights on cluster's are no gauge of just how serious the ill may be underneath. Thanks!
Agreed, the dummy light only tells you when there us a problem
@@BrickHouseBuilds the bike looks and sounds great. Hoping to find a SOHC in my shop one day. Take care my friend.
looking forward to the better weather i am a lot happier if i can get a few miles in
Same here
Rotella T4. I put that chit in everything~! Good stuff. And that's plenty of good oil pressure.
Absolutely the Franks Red Hot of oils lol
I use T4 in all my old Honda models. Good call
Hasn't let me down yet!
Far Out 👍
will i give it one more turn,well done,rob
Have enjoyed all your videos, especially the 750,I have a 72 which sat for 32 years way worse shape and was frozen, wish I could post s before and after, Wanted to put a gauge on but afraid of breaking the case, Funny,mine had almost the same handle bars. What were they thinking??!! Looking forward to more
Happy you have enjoyed the series! This bike has brought me a ton of joy and I feel that comes across.
That was more oil pressure than I expected from an open bearing bottom end!
These have traditional split bearings and not full rollers like say an xs650
@@BrickHouseBuilds I did not know that. I assumed they were more like a KZ1000 or GS1000. I had a 1980 CB650C but never had to get deep in it. My wife rode it from 17K to 45K miles with few issues.
It’s a plain brg bottom end
F the seat haters... Thank you for the effort you put into your content. I've done some marketing for you; see what happens.
I appreciate it 🙏
Nice looking bike!
Thank you much! Its riding the line of that perfect patina/character thing
@@BrickHouseBuilds Rims are just painted old ones or new?

Great short video. Very informative, educational & enjoyable to watch. Really enjoy watching your videos. Great videos of you* working on the bikes.. Thank You* for sharing much of what you do. Sincerely, a very satisfied subscriber.. David L*.💯👍👌✌️🎥🎬💖💞🇺🇸💎💎💎
Glad you enjoyed David!
hello good morning sorry 🙏 what bothers you but my english is very basic but I haven't been able to translate greetings
Well hello and good morning to you as well!
👍Good
👍
May have to get the guage for my 82 CB900C if it fits.
I assume there is an option for that bike but have never searched
nice trix withe aluminum foil . i watch your videos just for this
Glad you found it helpful! Keep a rool in the toolbox. Worth it!
I need some spares for my 750 four
Hi, really enjoy your video’s you do terrific work 👍, there’s something bugging me regarding the geometry on that monoshock set up though, I could well be wrong here but I think it’s self bracing and that is stopping the movement, not the high spring rate, 🤔, like I say I could well be wrong but did you try moving the swing arm with everything except the shock fitted?, ie support the bike on a centre Jack remove the shock and see that the swing arm can move with the hoop/brace etc fitted?, apologies up front if I’m wrong 👍🙂
Yes I showed that in the video a couple times with the strap
@@BrickHouseBuilds I think I may have taken too many hallucinogenic drugs before writing the above 😂, I realised my error and was going to delete it but weirdly couldn’t find the message!, anyway as I said in my subsequent message “great job” 🙂👍
(PS I now see why I couldn’t find the message to delete it, I put it on the wrong video, that’s auto play for you!).
I was thinking about using that galley for a temp sensor. Have you used any that you were satisfied with? Or, do you think being aware of pressure is a more important metric to keep tabs on than temperature?
I prefer pressure. You worry about temp because that therefore has an effect on viscosity and therefore pressure
@@BrickHouseBuilds Interesting! Thanks man. I like temp because it moves quicker (I think) and I like watching it drop once I start rolling after being worried about it getting a little high. lol But I will also experiment with pressure. Cheers!
Why was installing the pressure gauge the only way to stop the leak? New Orings for the plug not available?
Of course I could put an oring in it. I wanted a gauge
I love your CB750 series and I hope to buy one for myself but they are so rare where I live. I wonder if it's possible to add some kind of splitter there and add temperature gauge. I just love to know as much as I can about my machine. Also I see that you're not using any torque wrench do you find them unnecessary? I bought one just for a peace of mind that everything is like in the manual.
Glad you like the series and thank you! I believe temperature gauges are available for the oil tank actually. Harley Sportsters have a dry sump like these and an available accessory is an oil temp gauge that fits into the fill hole in the tank.
As far as torque wrenches I have a few and just picked up a really nice 20-220 in/lb unit for engine work. Outside of working on specific internal and external engine fasteners I generally do feel I need to use one as I use common sense and feel to know when something is too lose, just right, or too tight. I have also referenced my manuals so much that sometimes I simply remember about what the number should be and can get very close just by feel. What I cant show in the video is how I can feel the aluminum sealing washer on the oil sump bolt beginning to compress when I reach the desired torque. I cant show how the information my arm is gathering from how a bolt feels when it stretches. Just lots and lots of experience with torque wrenches, a manufacturing background with hardware as well as castings, and just common sense to know that a 6mm bolt is not going to be as tight as a 10mm bolt.
hey great video as always brother ...
have a Question that I'm sure with your experience you might have a pretty good idea what would be the cause .
I Have a 1976 CB750 Four , in dissent shape and been taking care of it on regular bases , when ridding it open road/HWY and full throttle it seems that i can't get no more than 65-70 mil/H top speed , any Idea what would be the cause ?
i appreciate your respond .
TY HP from Austin ,TX
Very neat install , could it also be fitted to the bars via an oil line ?
I mean it wouldn't be this kit. At that point you could make a gauge fit anywhere
I installed a pressure gauge on my 1975 K model back in the 70"s. I didn't have any leaks at that port I always had leaking where the tachometer cable plugged into the valve cover. I could never stop the leak. Does yours leak there too?
Oh man the tach drive seals always seems to leak just a bit. Ive replaced mine and it still isn't perfect. Not like a drip but just not a perfect seal meaning dirt and grime gathers near there as it clings to oil residue
Is that opening you screwed the gauge into there for slotting in a workshop gauge or some other reason?
No that is the bore for which they machine the oil gallery. Its a chamber for the main bearings.
😎👍😎
👍
Just wondering if you checked the correct side of the filter paper? I thought the debris will be trapped on the inside facing part
I may not have shown it but I inspect both sides. Lots of clips to make a video from so some may not capture exact moments
Lovely job! Silly naive question: when you said fitting the OPG was the only fix for the leaking gallery plug, did you mean that literally or were you winking and tounge 8j cheek when you said that?
Lol just tongue-in-cheek. A simple oring would have fixed the original leak but I wanted a snazy gauge
Hi BJ , love following the journey with your cb750 , Q for you , the close up at about 17:38 near the end ,.... there sounds like a lot of engine noise ( rattle ) , is this normal ??? Why I am asking, I have just bought a 1973 cb750 last weekend ( I had one when I was 17 ) and it is pretty noisy also !! Cheers , David ( Australia )
Yes these do make some noise. You are hearing some clutch and cam chain slop.
hope you replace the oil filter housing with a modiifed one with a 19mm nut not the 12 mm oem nut
I've modified the original bolt as it was stripped before I got the bike
Forgive my ignorance. Is it important to know the oil pressure? Would you mind explaining why? I have a 1970 CB 125 and wondering if I should do this, besides having it look cool.
Well this bike has a more cloudy history as far as engine health so for me it was a fun thing to add for sake of science. Most bikes have a simple light that glows when there is no pressure but that doest tell me what I want to know. I wanted to know idle pressure and revving to pair with other data for the bike. I can also see how the pressure changes with temperature. Not necessary but something I wanted for this bike
Hi men, excelente video. I have a question for you.
I am installing on my Yamaha FZ6, (Inline 4 cylinder engine 600cc) a oil pressure switch because the bike has is a oil level, and i am more confortable with oil pressure indication, but i dont have a oil pressure gauge to see what is the aceptable nominal idle oil pressure so i can put a switch acordinly.
Do you think that being so similar bikes, maybe i can count with the same 30-35 PSI at idle? considering my workshop manual says it should have 34.1PSi at 6600rpm. so considering that iun your video, your gauga shows a little more than 60psi at some higher rpm than idle and then it lower about half.. i think its safe to see i can count on about 20 PSI at least at idle, i am right?
thanks!!
I would never assume two very different engines would have identical pressures. There are many variables that go into this. Things like bearing clearance, oil viscosity, bearing types, etc will all have a different effect. Your shop manual has the correct info here as that is specific to your bike.
How far out does the gauge reach? I worry that if the bike falls over on the right side that the gauge could break off and damage the oil galley. Thanks
I mean does it matter? If it falls you run that risk regardless with the points cover a d potential crank damage.
El MA2 es importante para el embrague
Correct
Very helpful and yes "depression" has set in lol
Its getting close here. Weather shift in full swing
Put a gauge on mine in the 70s 👍
Definitely a worty mod
What oil would you recommend for a ‘71 honda cb350? I use non ethanol gas for it
I put Rotella 15/40 t4 in everything.
はじめまして。 この時代のバイクに興味はないけど、クランクケースに打刻された〝MADE IN JAPAN〟が誇らしい。
Great things made there
Do you have a link for a gauge like that, I have a 1977 Honda cb750
Already linked in the description
I put the same gauge on, now the oil is squirting out of that hole on the side of the gauge !
Thats not good. Did it do it right away or after some time?
@@BrickHouseBuilds A couple of years later.
I have no history on my k5 ,25700 mls ? .when i finally get all issues sorted i will give it my first oil etc change. Did you run any type of engine flush or just filter and oil . Cheers.
When I get an old bike going I will change the oil after just a small amount of run time. Maybe 100 miles at first, then at 1000 miles.
Do you run your fuel lines in from the top . ?
Anyone else enraged by these 18:36 bars?
what was the coast to make it road worthy ?
Actually working on making that exact video!
Dobra ideja ali.... instrument za pritisak ulja, kao i crvena lampica za ulje, mora biti u vidokrugu vozača tj. na upravljaču. To znači umjesto instrumenta ovde priključiti crevo a instrument postaviti na upravljač. Nezgodno je kontrolirati pritisak ulja gledajući u čizmu tj. na dole. Poz od mr. Turbo.
You don't need to watch the gauges all the time. This is fine. Don't put one on
Those bikes will do over 100,000 miles easy.
I would seriously love to crack that number on this bike
A great add 👍🇬🇧
Thank ya
Don't know if its the video but it sounds dead rattily, that engine?
These engines sound like that normally
A frend of fited one i said i did after o while i removed it why i kept looking at it so i removed it so did my frend i would every 2000 thousend miles re fit it to check oil preshure change oil every 2000 or one year new oil is the best macanic also use the recomended oil ie 10 40 i use 20 50 in 70 80 motor cycles 75 year old biker no car licence uk citecen
I haven't had any issues with constantly looking at the gauge. 15-40 Rotella goes in all my bikes
If you take care of her and I know you would, you could add up to 100k or more to it than just re-ring her and add 50k or more! I put 75k on mine with a 915cc kit in her. These things are built like a tank, way over engineered!! I have a friend with one that sat for 3 yrs. under water in a river. After the cops retrieved her, he just flushed the eng. and carbs x3 times and he's got 87k on her now and running strong. HONDA'S!!! Fuel tanks???? well that's a diff. story!!! LOL
Damn thats crazy! Sounds like a challenge to revive a river bike lol
@@BrickHouseBuilds Ps. Always carry the cap with you as that thing is the first to go in a tip over. Don't ask!!! LOL
Question.............does anyone produce/make an analog Oil-pressure gauge for CB750 Nighthawks 91-03??? I have one and would Love to find out if they do or not! Thank You. : >)
That I do not know. You will have to google that and go through the forums to see how others have gone about fitting one.
@@BrickHouseBuilds Thank You. I appreciate you taking the time to answer my question! : >)
@@menom7 of course and no problem
Regular oil changes saves engines🤪 old oil destroys engines
Agreed
Nice! Did the same to mine a few months ago. Good to know about the idle psi range once warm. To be honest, my ‘75 CB750F has a rather unknown past and I’m frankly not an expert on it (although I’m trying to learn) and was wondering if the psi I was seeing was normal or not. Video of mine here: th-cam.com/video/Fp4fsZmlJy0/w-d-xo.html
Well that unknown past is why Im doing things like this gauge to just know for sure what its doing.
Once again thanks for making these videos! Really enjoy them!
👋👋👋🧏👍👍👊

Good job. Save that tinfoil, it makes for good hats.
😂😂😂 As I have heard
And you can get several radio stations in your head depending on where you cross your eyes.
a wink
hmm who wonder what does that mean.....
I thought i set up that joke well actually
It's an oil GALLERY not galley.
Well in order to keep the video length in check as well as save on text I leave out the "R." It saves a syllable each time and again cuts down on letter usage. Audience retention is very important and they demand I keep it as short as possible. 😉
My CB has no analog gauges, and now I regret it... haha, time for a style "switch".
I love digital as well as analog gauges but they have to match the vehicle they are on. This bike is definitely analog.
Hey I have a spare 74 i used as a parts bike. Let me know if you need any parts or better yet let me know if you want the parts bike ill give it too you along with the title. Im not to far from you. Im in the middle Georgia area
I appreciate it but no need currently
