This is a super helpful video...I love how you don't skip the "easy" parts like taking off the front wheel or brake caliper. It's definitely helpful for us noobs out there learning as we go.
Thanks for watching!
This appears to be a much easier process than the common-motor vids portray. Thanks for sharing!
Thank you for the video Taylor I truly appreciate your assistance and time with the production of these type of how to videos.
In fact I am currently restoring a Honda cb72 and I searched UA-cam for assistance with fork seal replacement and as soon as I noticed you have created a video on the subject I went straight to it. That is because I have been following your channel for some time now and I have found your videos to be very professional and I trust you to know what you're doing. I think it is awesome that you are prepared to share your knowledge and I understand that it would take quite some time to produce such videos. So thanks once again your efforts are appreciated! Cheers Robert (Tasmania Australia)
Would be very useful here to know the year of the bike. But when I search for CB750 fork seal, this is the best video I have found. Thanks for the videos.
Excellent. I followed it to replace my seals on a 76 XL250. Thanks
Dustcaps look better indeed. My VT500C had these as well but they are not that effective in keeping the dead bugs out of the oilseals and thus damaging them. So I put on those rubber sleeves. Looks not as neat but saves me a lot of work.
Thanks for this instructive video ! 👍👏🇳🇱
The inside looked similar to my 1972 Sportster ..thank you for sharing . It was well explained .
Incredibly helpful, thank you.
this was extremely helpful thanks for doing it!
Really enjoying your channel. I'm trying to get through all of your videos that I've missed.
Awesome! Thanks for watching.
t boned a car who pulled out in front of me and bent both forks on impact, gone be replacing them and the headlight on my cb550. Thanks for the video!
hell yeah. Thanks for this and all of your videos!
Really nice job of showing, thanks so much, I'll try it.
Great job, very useful putting together my cb550.
I liked the look of the old boot.
Great video! but next time you put your seal back in, grease it! It wil help preserve it better! Its pretty important so you dont blow a seal any time soon! Other than that keep it up man! I love your videos!
Thanks for the tip!
What kind of grease should be used?
The owners manual for the Honda CB550 says to use ATF (automatic transmission fluid) in your forks not engine oil. Just thought I'd add that. Great video tho, very informative.
It changed between the early years and 77-78. Just do what your manual calls for
Great video! Incredibly helpful, thank you!
Thank you very much for this video! I was waiting for you to do it before i did mine haha
Also how did you clean the inside after you took out the old fork seal?
Also i have a 1981 honda xl500 how do i find out how much oil and what oil to use?
Get the service manual. You can find them for free. Here is one spot:
mybikemanuals.com/honda/227/
Usually with Hondas, it's not right in the section about the front forks but instead is in a table that contains lots of measurements...like how much oil to put in the engine, how much air in the tires, etc
Thanks for watching. I used a little bit of brake cleaner and some shop towels.
Helpful video. Personally, I like the look of the stock fork gaiters better. They beef up the front end.
awesome videos, iv learnt some handy tips from you.im in England and im currently building a 1982 Honda cb650z brat, and a 1980 suzuki gs550 brat. keep the videos coming! you should get some tool box stickers made! because I'd have a few!
I'm working on getting a more permanent store setup online. I would love to keep a stock of tee shirts and stickers for people who are interested. Thanks for watching!
Excellent video! Thanks
Great channel! Your videos are very informative and fun to watch! I'm in the process of turning a Suzuki TS-250 into and cafe/brat style bike. More videos of that coming soon!
Awesome, thanks for watching!
good video. clear and clean. thanks.
Great video! I'm working on cafe ing my cb250 nighthawk. It's coming along steadily!
Thanks for watching!
Great video. I have a kawasaki kz400 1976. The manual says the Fork oil is 5w20 so that it's engine oil? Any recommendations? Thanks in advance!
Great video! If I want to shorten the fork internaly, do I cut the spring or the tube? Or both? Thanks
Are those forks shortened/cut?
what is the torque spec on the upper and lower triple tree
amazing job, What muffler did you use on this build?
What type of motorcycle stand is that? Cant seem to find one for my honda cb
Thx a lot!
What did you use to clean the forks with?
Love your vids man , SUPER HELPFUL!! I’m trying to find the fork seals and dust boots you put on that 550 for my 72 cb500 four. No luck , will these 550 ones work ? 👌🏼
Ready to try this out on my 550 but I can't see how you got the bike to sit upright like that.
Nice video!
What product/method did you use to clean the forks?
Great video! I must say I like the look of the gators- stupid question- could you put the gators on with those seals if you had wanted too?
Yeah, you can go either way. I go back and forth on which ones I like better.
Mate, some great vids on maintaining these old bikes. Handy resources now and for years ahead. I've pulled down the front end of my 350F and was hoping your video included re-aligning the forks after fitting back together. Do you have a preferred method for re-aligning the forks and triple clamps?
I just use a small 6-inch scale and make sure I push both forks through the top clamp the same amount.
Excellent. Good timing! I hear if you want a stiffer front end you can add a little more oil?
No, the amount of oil won't affect the stiffness. If you want more stiffness, you can buy a progressive spring or even better, cartridge emulators. They aren't very expensive but will make your front end feel much more responsive like a more modern bike.
Can you recommend progressive spring brand or cartridge emulators? I'm 6'1" and 255 so I think I'll need a stiffer front end.
What type and year of bike? Is it a Honda CB550 like the one in the video?
78 cb550F K4
Then go with RaceTech springs and gold cartridge emulators. That is the popular choice for the CB's.

Hello, great video and very informative I have a question. I have a 2000 cb750 nighthawk. I'm sure that my bikes forks aren't too different from yours. My question is that, there is some rust on my fork and so I plan on rebuilding it. If I plan on doing it myself I'll just need the fork seal clovers? Not an actual rebuild kit for the inside components?
Sorry for the dumb question.
If you're just rebuilding them for cosmetics and not because they're leaking you could probably get away with not replacing the internal seal.
I might be wrong cause the angle was funny but you put the spring the other way around. Its a progressive one so the part with more density goes where the applied point is moving witch is the top of the fork. I hope when the spring goes of camera its getting turned. Very nice videos by the way, i suggest you follow Moonfleet41 for some guidance in mechanics. The guy has tones of experience when its comes to bikes and especially bolts, seals and general how to knowledge. You may want to learn some tricks about products to use with bolts for maximum perfomance through the years.
classic Octane.
love the videos... I was wondering if you could tell me what wheels you are running and what size and brand tire you are running front and back?
Bridgestone Spitfires. 100/90-19 and 110/90-18 on stock rims.
Random question, not really related to the video.
But i have a xs650, with kick start and the usual electronics. Was wondering if you think that a 4 cell anti gravity battery will work for my bike.
Thanks in advance, Potentially.
I would think so, especially with a kick start. You don't need the extra capacity to run a starter. Thanks for watching!
Hey great info vid bro, where can I order a set of the front fork shock covers ?
Thanks again
Jr
I would check out 4into1.com they should have what you're looking for.
Do you know where to get replacement snap-rings?? Can't seem to find them.
just a guess, eBay
When putting the fork in again, how do you make sure that the length of the two forks matches? did you eyeball it?
Stock they fit flush with the top triple clamp. I usually go about half an inch past it to lower the front end just a little bit.
Thanks, I'm thinking about getting a CB 550 to learn how to work on old motorcycles. I was wandering if it's the right bike to get started, or if I should rather get something simpler like a Yamaha SR 500.
I think it's a great bike to get started. They are super simple and all the parts are easily available.
Nice bikes! I have a 73 CB500. What small battery do you use? I've been having trouble with my Shoria Battery....
I have a Shorai on one of my CB550s and it’s been working for me. I have an Antigravity 4 Cell on my Triumph but I don’t have an electric start on that so it’s enough. You could look into the Antigravity 8-cell.
Feel free to send those fork socks down to Houston! Hahaha I'm redoing and cl360 and had the dust boots but really want the socks
Message me your address and they are yours.
Classic Octane 🙉no way! Ok!
What kind of handle bar is that
What do any of you use to clean out the oil and the gunk in the forks and oily parts??
brake cleen
I have a 1983 CB1000c and I've been looking for some of the classy/timeless gauges you have on the 550. Can you point me in the right direction?
Here you go amzn.to/2ibM0WW They are from Dime City Cycles.
Classic Octane You're a class act!!!👍
How do you source parts for these old bikes? I'm rebuilding a 1976 Suzuki GT185 and I'm having trouble finding parts
Google works, ebay, Amazon or motorcycle junk yards, heck some junk yards are now on ebay, and also networked together for easy finding of parts. Pay more because they gotta take the parts off. I surfed to this site because I wanted to see how a rebuild is done. But I wonder what year his CB550 is. The one I got my eyezzzzzzzzzz on is a 1976, the tanks look about the same.
Great video, but I way prefer the long fork Gators. Makes it look.mean.
Can I safely put some 2x4s on my motorcycle lift and jack the bike on the bottom of the engine? My 4into4 pipe block the frame.
Sure, I have done that before without any issues.
hey man I'm
building a 71 450 any chance in thoese parts boxes you have a top bridge?
Yes, I do have one actually but to be honest i'm not 100% on what bike it's off of. It's not from a CB550 I know that, so i'm thinking maybe CB350.
where can I get a seat like that?
It's a flat seat form Tuffside.com If you get one make sure to tell them I sent you :-)
What tires do you have?
Bridgestone 110/90-19 Spitfire 11F and 110/90-18 Spitfire 11R. Thanks for watching.
Anything new with the triumph?
Just ordered some parts for it today. Should be tearing into it in the next week or so.
Classic Octane too psyched
What year is you CB550?
This one is a '74
It doesn't need to be fork oil for the CB? ...interesting.
It should be ATF. Not engine oil.
parabéns ajudou.
Please don't use Engine Oil in your forks. There was a supplement released by Honda that updated the SAE 10W-30 recommendation. Use Anti-Foaming Fork Oil, or ATF please. lol....
atf is the best but very few companies make different viscosities. Fork oil is just ATF but in different viscosities.
Do a video on the fork brace. Lol.
I have encountered that brand a few times now....
And I can't keep a straight face.
It's a 23mm hex not 24mm
Snapring
