- Replacing fork seals and boots on two Honda CB750s! Two familiar faces in the shop for the video with my blue 1975 CB750 I call "Pati" and a beautiful orange 1972 CB750 I have made videos on before. The mission is to replace the brittle and cracked original fork boots as well as the seals on the orange bike. If you have't seen any videos on these bikes before please be sure to get caught up by the links below!

There isn't much to me more satisfying than putting new factory parts on an old bike and bringing it further back to the time it left the factory. I always bought bikes that I liked the look of stock and that orange one is just magnificent. Now that I am retired bringing back a CB 750 to showroom is my goal. I love working on them almost as much as riding them and age has finally brought the patience I need to do it right. Excellent job!
Glad you enjoyed!
Congratulations Great video, always bringing interesting content to subscribers!!! For me, I always buy bikes and then customize them. I love the original design and that orange color is awesome. I enjoy working with them almost as much as I enjoy riding them
I like the blue one! 😊
Greatest tip for fork seal EVER!!! Must see!
It helps a lot for sure
I really enjoy seeing spanners being twirled and how another bike nut goes about his work. For me, there is poetry in these motions, with your patience and quiet determination having an artistry about them. I really appreciate your work. Thanks for sharing it. FWIW, I don't remember seeing a video showing the same job on two similar bikes before, the point being I liked you adjusting your approach for Patty. I was surprised actually how easy it seemed to be for you to support the weight of the front end at the same times as twisting the stanchions and rocking the whole unit to engage and slide the forks home. I said to myself, that's a mistake, way easier/faster to remove the wheel and do one at a time. I was wrong. Good luck with everything and don't lose confidence in yourself. You're great.
Well thank you! I thought it was fun to show that difference in approach so I'm glad you enjoyed!
Love these episodes! I can highly recommend getting a set of those hard plastic trim remover tools (cheap on Amazon) and while it may introduce a wee bit of mess if you don't prep for that ahead of time, spritzing in a bit of something like WD-40 in any crevasses that you warm up and as you pry out with the plastic tools, helps immensely with breaking the stiction that rubber or plastic has against itself or other materials. Just a thought. I spent years fighting damned sticky rubber or plasticized with age intakes/fork boots/grommets etc., before the wonders of heat+lube+safe prying tools lol. I now have several sets of cut down and sharpened custom plastic prying tools that save me soooo much frustration and time.
Definitely a good idea
Man you got an awesome building , shop or whatever you call it, so clean and uncluttered
Thank ya! I'm really focused on keeping it that way
@@BrickHouseBuilds I sure enjoy the 750 four content, I have a 75 I really enjoy
Remember when the 750 was the bad monkey in town back in the early 70's. Enjoyed the video, B.J.. RIDE SAFE OUT THERE!
Glad you enjoyed!
Doing an oil change, plugs, and air filter on the V-Strom tonight. Excellent way to end the week! Going to ride southern Kentucky tomorrow and Monday.
That will be fantastic! I'm riding the Strom Saturday
Brilliant!With the right tools, know how and a bit of trial and error, it can be done. looking to do similar with my XL700V. I was a bit concerned for my ability to do the job, but you have given me confidence to tackle the seals replacement with some nice hacks like the plastic bag over the stanchions to save the new seals. thanks so much! Great channel and inspiring newbies like me.
Glad it gave some good tips! Just take your time
That's a great tip on using a plastic bag to ease the seal over any corrosion
It's a simple and effective tool to have@
I would like having you for my bike mechanic. You do a great job. Wish I had a mechanic like you.
Well I appreciate that!
Your dog on the couch is beautiful
Haha thank ya! She's a derp
Absolutely love it when you work on the old Hondas, especially your 750. I just rescued a 1980 CB650 from a shed and got it back on the road (2152 miles, still on original rubber). I enjoy going back and watching your 750 playlist from the very start where you weren't sure if you were even going to keep it. So glad it is one of your favorite bikes now!
Daaaaang 2100 miles!!! Thats awesome! Obviously be careful on that original rubber but have fun!
@BrickHouseBuilds already pout Dunlop 404s on both ends, but did put 100 miles on the old rubber! BTW absolutely love that blue on your bike
Oh boy. I've done the front end tear down enough times to warn anyone off on trying the whole assembly like BJ did. This requires the bike to be tied down on a lift like he has done VERY securely because it is easy to topple the whole thing with the upward force required to get the fork legs back up into the triples. BJ is very experienced at this. Well done sir!
Definitely had some straps in the right spots!
I am looking at the picture wall over your shoulder and spot the pic with "HOLD ON, I've gotta overthink this" LOL!! Great vid you do great work
My mom got me that and I couldn't be offended lol
Love the look of the orange bike (and the blue one is just fine), the new gaiters certainly smartened both bikes, nice job 👍
They both really needed the simple parts. The orange bike looks almost perfect outside of that
Nice job. I’ve used plastic food wrap when installing fork seals, same as you did with the plastic bag.
Thats likely a better candidate than a plastic bag
Great job on those SOHC Hondas! We used to put the GL1000 front fender on these bikes along with a 16" wheel to give it a good look & stance, then a Kerker 4-1 header w/comp baffle to make it quite a bit peppier and have a nice exhaust note. Honda also used to have a dual disc front end setup for these bikes, hard to find back then, unobtanium now.
Keep 'em running, BJ! Thanks for a cool video.
I have almost all the parts needed to have a dual disc front which may be a fun project.
@@BrickHouseBuilds very cool! Would love to see you do that conversion on your blue CB750.
Cool shop full of cool CB 750's🛵
Thank ya Jim!
FYI ~ there were two bikes that I noticed on fb ~ OOPS, I'm not paying attention. Nice music. Sort of. and the plastic bag trick. Fork oil? I had no idea. Wow. So yea. Two bikes on fb very similar in vintage and make/model ~ one of these and one of the older nighthawks, both cb750. One 1987 and 0ne 1984. Both clean, yes but both were priced over 3G. Go figure. These videos are so helpful. Given the time I hope I can do this myself. Oh yea. I always wondered about the plate on the lift. Mine got smooshed. Those little clips. Oh yea. Nighthawk 95. I have an aluminum fabrication job that i worked on today so I may dig into that bolt tonight not sure at least tomorrow. Soon a Key. Maybe there's a sock in the light housing with a key in it. Maybe? Who knows.
Your videos make me eager to restore my late father's '78 CB750 Four. Black with nostalgic orange trim. Keep up the good work, and thank you for the fine details.
Glad they inspire!
Like a bunch of people , I really love your cb750 episodes in particular , I have a couple myself , and have enjoyed the journey with yours 👍🏼
cheers from Australia
Well thank you and I'm happy you enjoy the videos!

Much appreciated
Great video BJ.....,really enjoyed it.
Thanks for posting 👍
BG.
Glad you enjoyed!
My dad use to have a blue Honda cb 750 when i was in my younger teens
Loving the content Definitely looking forward to a clutch episode.
Actually just ordered clutch parts last night so thats happening soon!
Another great video. Thanks for posting.
Glad you enjoyed
Nice job, and very well done! Regards from Canada 🇨🇦
Thank ya
Great tip on the Ziploc bags BJ!
It's a must!
Nice job and sharing everything make it even better. You don't give up easily.
Awesome work as always.
Thank ya!
Cracking job BJ absolute love both of them think one of the best bikes Honda ever produced in my opinion take care buddy and all the very best shop is looking mint by the way 👍👌🔧🔧🔧❤️🦴🦴🐾
This orange 72 is an absolute looker and id argue one of the best ones made for sure
Defo mate 👍
I love these videos. Another motorcycle on my list to ride.
A classic cb750 is very hard to beat
@@BrickHouseBuilds I looked up the stats for a 1976 model. 1/4 mile in 13.5 seconds at 100mph. 67bhp. 50ish years old and still capable.
You have a really nice shop
Much appreciated!
The baggie is a cool tip. Give ya a tip back... Never use red thread lock on a motorcycle. That stuff is for big vehicles and heavy equipment. Motorcycle manufactures have even restricted using it in the last few years. Blue at the most. If you tighten to torque specifications, then really no need for any of it. Not hating, just offering some advice. I enjoy your vids. I recently obtained a barn find '72 750. Gonna strip her down to the frame and restore her.
I generally use red on the fork leg bolts and key fasteners on bikes that vibrate excessively like my xs650. Otherwise I use blue 95% of the time
It never ceases to surprise me how complicated forks are to re-seal. It's not an easy job.
It can be a bit complicated for sure
I just got my hands on a '77 and want to get it restored and roadworthy again.
Pretty cool to see 2 similar vintage bikes side by side on the lifts! I have never tried putting a bike on a lift backwards, doubt I could.
It's so awkward to put them on backwards. Takes me a few tries
just beautful bikes..Honda..love em
That they are!
A nice brace of honda 750sBJ and a good trick with the plastic bag 😊
🤘🤘
I am in love with the Sunrise metalflake ! my next built will be paint like this . Regards from France
It's so good! Glad you enjoyed
Great tip with the zip lock bag, have ruined a few seals putting on over pitted shafts. Thanks great video.
Glad you found it helpful!
Classic bike beautiful style
Agreed
Biggest takeaway: backing a bike onto the lift. Many years wrenching but only recently got a lift and want to use it for an upcoming fork seal job and was wondering how to do it on the lift, so this helps.
Backing a bike on is much more difficult but made sense for this job. Definitely use an extra set of hands rolling it on backwards as its very awkward
Also, I had a 1971 CB750K1 in gold/orange. I loved the engine, the riding position and view over the clocks, the sound. But the handling was not for me - hinge in the middle. I got the swingarm bushes replaced by a bike shop, with genuine fibre bushes installed. There wasn't much improvement. I regret not looking into phosphor bronze in hindsight. Maybe that's something for you to consider.
I actually have a set of bronze bushes ready to go on!
John Farnham nice he has been very sick but getting better.
He has a voice to say the least!
Super well explained,what more cloud you want?well done,keep it up 🤙👍
🤘🤘
The close up of the orange tank - that is a lovely colour (although doubt it would suit a newer bike)
Such a good color indeed!
Dang never seen the plastic bag trick for the seal. Very nice. I’ll be stealing
It's a very good trick to have. Really helps save the seal
Love your content, Ihave a 1970 Honda sl100 that I’m going to fully restore.
That will be really cool when done!
😮 brill vid wish i could do my own work on my bike but not got enough confidence .my zzr 1100 needs idler jets cleaning tckover is very wooly but darn't try myself
Love the colour think you need to start shopping around getting as many Old bikes as possible every one seems to be doing the same or the prices will go through the roof So get shopping ASAP 😮😅😂
I buy a bunch of them thats for sure.
Great work BJ 👏 Two beautiful Honda Motorcycles . It wouldn't surprise me if Honda put these bikes back on the production line with obvious changes to abs and emissions.
These bikes look so Cool 😎 compared to modern plastic models.
Don't get me wrong l love modern bikes, l love all bikes but l believe there's a market for the 70s Houda 550 and 750 four.
They did try with the CB1100 but I guess nobody bought them. Those bikes look fantastic and tick all those boxes in my opinion
@BrickHouseBuilds yeah the 1100cc was never going to sell . Insurance over here in Ireland UK and Europe is astronomical The 550 and 750 would be affordable for all ages.
My cb 500s 2002 is perfect for Irelands coastal roads, very enjoyable 😉
I can’t get over how beautiful that 72 is. Love ol blue too, but something about that orange. It’s just screams 1970’s.
I need to do this to both my 74 and 75. Went out to the garage and saw a puddle of fluid coming out of the bottom of the fork. I can’t remember if you upgraded the steering bearing bearings on the blue bike? But was thinking about doing that on both bikes while I had the forks off.
Keep up the awesome work!
The orange is just amazing looking. I did do a taper roller conversion on the blue bike but have never had the front end off the orange one
I have new boots for my 750 but haven't put them on yet. I figure when I replace the fork seals I'll do the boots. That ring at the top of each boot has always been a bit of a mystery to me. I think I found one video that shows the proper way to put the new boots on. I like the zip lock bag trick. Most videos i've seen they pound the seal into the bottom part of the fork then put the tube in place, but putting the seal on the tube first seems better.
Some bikes you can install the seal then the leg but for these you must put the seal on the leg first
Hey BJ, great work and love the way the front of your new workshop has come out! Excuse my ignorance but what’s the wiring at 5:23 on the left fork ear connected to/for? I wouldn’t have expected there to be any electrical components on that part. Just trying to learn more about my CB750 as I’ve yet to do any fork work on it. Thanks in advance if you manage to see this! Keep up the great content!
No worries! That is for the turn signal beeper. It's an incredibly annoying beeper from the factory. You can hear it in action as I test the bike in PT2 of the linked videos
@@BrickHouseBuilds Ahh that makes sense! Appreciate the reply!
Great vids, how do you find those wheels chocks on your benches! Looking at getting one
Those came from condor! I actually have a dedicated video on the chock details and how to set one up in this video! All details within so please check it out ruclips.net/video/l2QlgdAOfxE/видео.html
So I was looking for people's 0-60 times on these. They're 7 seconds and under right? People were arguing that 0-60 doesn't matter, but in my opinion 0-60 matters because it's more about how quickly you can get up to travelling speed in relation to traffic. I always think about on ramps for interstates being the best place for a having a good 0-60 time, rather than a racing context.
I have zero idea what the 0-60 would be. It's perfectly adequate for getting up to highway speeds though.
@@BrickHouseBuildsYeah, that's exactly what I thought man. Bikes are FAST. I think sometimes people don't realize how fast even a "slow" bike is.
Another good video. Love 750s. Have a 72 same colors. Did a gl1000 front end. Have a 75 that I want to do. Want to do a750 dual disc. Have you done one. ???
I havent done a dual disc but I have 80% of the parts to do it to my blue bike. Its tempting
Would like to see it and a list of parts to do the job . Have a 75 that I want to clone to a 70 and was thinking of doing it. I to,gathering parts for that build. Keep up the good work...Doesn't. Ook like we can share pictures of our builds. Maybe some which you've inspired. Keep the pups in there too!!!
HI BJ, do you know if there's a specific reason that the blue bike has had it's ignition switch swapped over to the right side of the bike?
I prefer them on the right side. I do that to all my bikes when I can
@@BrickHouseBuilds OK Thanks
For a complex multi step process like this, it would be really helpful if you were systematic about explaining the process, step-by-step. You were sort of all over the place and for those that have never done the job before it could be confusing.
Maybe at the beginning of the video, layout exactly what you’re going to do step-by-step, and then show that. Explain what you’re going to do then show each step with comments in VO to explain any details that might be confusing. What do you take off first, how do you order reassembly? Tricks like your plastic bag one (which is one. I’ve never heard of- it is a fantastic tip btw) can be commented on in voice over too.
For example, you disassemble the shock assembly but details like what seals going where what tools are you using? Is there any preload on a spring, torque settings? How much oil goes in each for tube? Where are you sourcing your replacement parts? You obviously know what you’re doing you’re just not telling us exactly how you do it.
Just a thought.
Many out here in RUclips land are trying to do the job you’re showing, and if you don’t lay out all the steps, they might miss something.
Great, looking bikes. I have my dad’s 73 exactly like this orange one. Sadly it’s nowhere near this condition but I hope to restore it one day. Thanks for putting out these videos.
I appreciate you watching. This wasn't intended to be a specific how to video but rather just something easy to watch as a lot of my audience likes to "hang out" in the shop with me. Normally if it is a how to video I have that in the thumbnail. It's also a battle as every time I do a how to I always get comments that are extremely rude saying I have no idea what I'm doing so I tend to just not want to anymore due to unfortunate backlash while trying to help.
Hey Bj, have you come across a honda cb700sc nighthawk, I'd give me left arm to see you to a restoration on one of those!! Pa I have one here in Ireland, needs work to get back on the road, oil cooler, leaking, carbon floats sticking from been left lying up
Those are such cool bikes. If I found the right one in black/blue needing work for cheap I'd jump on it but I haven't done so yet
@BrickHouseBuilds I've seen loads pop up in the states for very little, even the black chrome exhausts go for few 100 dollars, it's the shipping to Ireland thars a killer
Nice bikes, wish I hadn't sold my old CB500 four, the little sister (maybe prettier?) to the 750.
CB500 and 550s looks equally as good
Hey BJ. Didn’t you have a 6 cyl Benelli you were getting running?
I have a sei yes. It's still a ways off on the priority list though
Hey mate, is that chopper style CB750 yours a freinds or customer? It's got the 4 into 4 pipes and other great parts you can swap if it's yours. That orange one was nice. Actually did you notice your front forks were in better nik than the orange ones. All good Bloke. Really enjoy your channel. Would of loved to come to your open day. Australia and you are too far apart in distance.
The chopper is mine yes. I don't plan to make any changes to it as it's very period. For the forks on the blue bike I did swap those with a cleaner set from a 78 I have as they were pitted like the orange bike.
What wheel chock do ypu use for the back?
The same chock as the front. It is a condor sc2000
Question? If the boot is already ripped off, why not simply cut it off with a razor blade?
Well it's best to avoid gouging the metal which a razor blaze runs the risk of doing. They still need to be unseated from the grooves and once that is done its no extra work to slide them off since you need to have the forks off to install new ones.
رائع 👍
🙏🙏
Would this procedure be similar on a ‘78 CB750F?
Well those don't have fork boots but replacing the seals would be very similar.
@@BrickHouseBuilds yeah that’s what I meant sorry, the innards of the forks.
Putting the fork boot onto the top part and getting it attached before putting the tube in seems like the way to do it. (Although you did it both ways, and didn't have much trouble with either.) Not sure why Honda didn't have those two caliper bolts enter from the left side. Going in through the spokes seems like a bad design. I think on other CB's the bolts went in from the left side.
Could be yes but not much trouble at all to do it after installing the legs
No way John Farnham You're the voice from Hot Rod

Has any environmental group done a study on how enthusiasts are saving the planet by repairing old equipment with a "few" parts vs buying a brand new bike (all new resources pulled from the earth)? Seems like it should at least be a foot note somewhere for making these machines sustainable in the long run
I've wondered about this exact thing very often. Could it be argued that say my 1975 cb750 is more environmentally friendly than a new Prius? I'd love to see information on how that could be extrapolated. For the old stuff it has already had its minimal manufacturing impact and then a tiny amount of pollutants over 50 years versus a modern vehicle that takes many precious metals to make. Very curious
❤❤Uncle, how much is the price of the engine, and what is its model? Uncle, it was very good ❤❤❤
Glad you enjoyed the video
Give those old Hondas some maintenance and they will run another 50 years.
They will outlive us if taken care of!

Heck yeah! Many only remember the fat boy from T2
@@BrickHouseBuilds A very beautiful motorcycle. With two exhaust pipes on each side. Unfortunately, I couldn't afford to do that. I bought from the same line, but younger than the 2006 Honda CB750 RC42.
How can I buy it from you?
