- ITS FINALLY FINISHED!, In this episode you will see it running and driving :)
/ rrcrestoration
This episode begins with a part that a lot of people were really curious to see restored and that part is the engine. The Honda C90 engine is a pretty simple little engine to reassemble and if your interested in learning about engines and how they work i would highly recommend that you buy one of these engines and disassemble and reassemble it as you will learn a lot about the basics pf how engines work from it.
Anyway The first step in the building process is to assess all the parts make sure everything is within spec and is present before building then its a case of assembling it all in the correct order and of course dont forget to use lots of build oil when building as you dont want any metal to metal contact when you first fire up the engine again.
Once built up it was time to put it back in the frame. the aperture edges were masked up to prevent any paint chipping then the engine was jacked into place and bolted up. After this was done the sprocket and chain were fitted and tensioned up to there correct sag and then the rear spindle was torqued to spec like i said i would do in the last episode ;).
Then it was simply a case of working through the bike methodically fitting all the ancillary items like, chain guards,rear pegs,lights,casings,horn, finishing the wiring etc after these jobs were complete i turned my attention to the detail items that truly make this a top class restoration, like refitting all the oem stickers in there oem places.
Then came the fun and nerve racking part, would it fire into life? Im glad to say after a few kicks it roared into life and i could get a drive on it again and did the best filming i could in the weather and lighting conditions.
So i hope you've enjoyed this series of videos as much as i have filming them for you and as usual there will be plenty more videos to come on the Really Random Channel.
See you all again soon

Hey Guys, As you have probably noticed already i have updated the channel name and logo. The channel is no longer Really Random Channel it is now RRC Restoration. Just incase you were wondering why the water marks in the video still say Really Random Channel. Enjoy.
Great job, just wondering are you collecting them or sell after restoration?

Absolutely beautiful job Sir. I had this Sport 90 model in 1966. My father bought it for me as a surprise for my 16th birthday. I rode it 300 miles the first day with my friend and his 150 Dream. What a day it was for the both of us!
Hey, Thank you for your comment and sharing your memories with the channel its very much appreciated.
I was a motorcycle mechanic back when these little engines were popular the Honda 50's 60's, 70's ,90's and 100's were some of the best engines ever produced ! They were just about indestructible
hey Ron,- Greetings from Germany ! Someone (Trike?) in the comments said this:
Quote >no grease on the bolts surprised me though(torque settings would be different unless specific for a dry fit)
This thing belongs in a museum. What a superb restoration loved every second of that.
These videos brought back so many happy memories of my first ever motorcycle back in 1978, a rusty seized Honda C90, got it running and painted it with a brush and used to get to college... and my first feeling of independence. Crashed it so many times pulling wheelies and trying to get my knee down...
Love it! Thanks for sharing your memories with us :)
@@RRCRestoration If you hold the gear lever down and build the revs up before you take your foot off it , it's like dumping the clutch, you can even get it up in third lol
Amazing job!💫💫💫💫💫
From a bicycle then learned to ride on this little C90 from my Dad, fond memories.👍🙂
Thanks for sharing.✌🍻
I had a C90 when i was 23. I bought it with my first job. Then I sold it to a frien when I got the chance to go study abroad. He's widow still keeps it as a memento of him. Darn, after watching this series of videos I want another Honda scooter. Thanks for sharing this series of videos and for leting us know how one should take care of those great machines! AG.
Thank you very much for leaving a comment and sharing your memories with us :)
That whole series was magical. Many thanks for your efforts and please do many more!
I’ve never binge watched a UA-cam channel before but this is exceptional. Utterly mesmerising, beautifully edited and wistfully comic at times. Superb camera work and unobtrusive and informative subtitles. Top drawer. Thank you very much!
wow, i watched everyone, what a credit to you, i wish to god i had the knowledge you have, ive just bought one myself, very nice condition, but yours is a show stopper, well done and thanks for sharing .
Only recently came upon your channel and love it. I know this build is not new but having just watched it I must say your attention to detail and enthusiasm shines through. This wee bike is better than new. Been watching my way through your videos. Every one with professionalism and knowledge. Also appreciate the way you film your rebuilds. must take a bit of time. Loved the bike in the dark and shining a light over it. Honda marketing could learn a thing or two from you. Well done.
This was the greatest restoration series in the history of UA-cam!
Fantastic transformation. The content, filming, and detail were total professional.
You have spoiled your subscribers, which means you must plan another
restoration soon. A+ Greetings from St. Paul, MN USA
Thank you very much for your very kind comment :) Im glad you enjoyed the series :)
There aren't enough words to describe how much respect I have for what you do! Your re-build is meticulous and your videography and lighting are superb. I rode a Honda Sport 90 back in 1967 and later a 160 Scrambler. I loved them both and I'm sure you are having a lot of fun on yours. If you ever rebuild a 305 Super Hawk or a Scrambler, I'm a buyer. Just let me know.
Thank you very much for your kind comment :)
Just bought a 1980 c70 in aqua blue 9000 miles full restoration like this photos to prove played 1800 quid for it reduced from 2200 ono .I've had twelve of these bikes since 1987 my first one a c50 cost me 50 quid those days r gone they r fetching serious money now decent ones worth every penny love them .
I’ve been meaning to watch this series for months. As a young teenager in the early 70s we all knew that lad who had a placky Honda that wouldn’t quite pass its MOT. In fact most of them were lucky to pass the end of the street and that’s with the fact we were pushing them on public roads...honest. I never thought it would be a motorbike I’d get nostalgic for, but you have shown me it certainly is.
A brilliant series of videos, wonderfully constructed with all the information there we need. Everything about your production has been spot on.
The restoration itself is nothing short of amazing, even new they never looked so good. And the detail you went to to is absolutely phenomenal, each individual piece was the equivalent of many people’s 'restoration' videos.
All round a job you should be very proud of, well done.
Thank you so much for your kind comment :)
Outstanding work, a real pleasure to watch having spent so much time maintaining and repairing my own machines in years gone by. I had C50's and C70's in my time but never a C90. You just couldn't kill one if you tried, I had one C50 that I repaired (back end, usual rot). I rode it for a couple of years, gave it to my Father- in- law to get to work on and then he bought a brand new one. The old one had gone round the clock and then some and never missed a beat. It ended up as a field bike for the son of a work colleague to ride on some land they owned. It went on and on. Great little machines. Well done Sir.
Thank you for your comment and sharing some of your memories with the channel :)
@@RRCRestoration Hi, 2 years later and I have just watched the whole series through again and enjoyed it just as much as the first time. So sorry, but I just noticed I never put a 'like' on your reply last time....We shall remedy that right now. There, done 😀😉
Wow...awesome restoration.
I first learnt to ride on this exact bike at 9yrs old. Loved it's simplicity and reliability. Great bike.
Outstanding, get yourself in front the camera and take a bow fella.
I had one about 50 years ago. Was black. This brings back memories. Great job from California.
Thank you, Glad i could bring back some memories for you :)
Great series on a cool little bike.
Coming back here from the future it's like I have gone deaf without the voice over !
I enjoyed this way too much. No nonsense, just super helpful clear process. Bravo!
Ahh love it! The rain and wind noise was fine but seeing the bike start up and get going was a treat.
Wow. When I was a boy, I never really appreciated this bike. 20 yrs later, damn how iconic is this. Great job man. Keep it up. One new subscriber right here.
I am seriously jealous of your knowledge and your workshop. I hope I find a guy with such knowledge and dedication in order to rebuilt my '82 C50.
Watched from 1-6 and really enjoyed it.
just goes to show you dont need it to be some superbike, to get to get a buzz from a resto, top man.
Thank you for watching :)
Great film ,especially for the novice to see how easily it can go back together if you are methodical-no grease on the bolts surprised me though(torque settings would be different unless specific for a dry fit)Big thumbs up for giving a Cub 50 years more life.
Hi thanks for posting this I just stumbled upon the series and watched all 6 episodes back-to-back I've restored a few myself I have a cm91 have a ct110 and I'm just about to start on my S90 project but nothing to the calibre that you've done some amazing work thank you so much
You done a wonderful, beautiful, professional job restoring that one of a kind Honda C90, Honda should hire you as a restoration restorer!!! WELL DONE MY FRIEND!
I use to have a Honda 90 , i watch this from start to finish and it was very enjoyable i must say , you got a real talent there and i will be watching any more renovations you do , very well done
Just watched the entire series. Superb restoration of a classic small moped. I used to be pillion on the back of my Nan’s C90 many decades ago when I was a kid. Loved them ever since.
One of the best restorations I have ever seen. I have great appreciation for your keen attention to detail
Mate, this video was totally addictive, your enthusiasm, and perfection for detail shone throughout, well done, and thank you.😀
Thank you so much, Glad you enjoyed it :)
Absolutely Fab Restoration , better than mine when it was new, if all manufacturers took that sort of care when building things. Great Job Mate Thanks for the share !!!
My friend! I have never felt so blessed watching a video until now.
You are an amazing human being.
Thank you for sharing, and your hard work!
I am sharing this with all my friends.
Greetings from Greece.
You will always have a place to stay if the road ever brings you here, let me know!
God Bless!
You must really love this bike enough to bring it back to a factory-like finish! The work hours alone was more expensive than the bike itself. It's beautiful.
I remember my grandfather used to ride this. This thing is a tank. It’s 50+ years and that thing still running lol
DAAAMN!
I have a red Honda Supercub 1981 from my Dad (1st hand), still original. I fixed it and looks beutiful classic.. still using 6 volt battery, & still using poin breaker, and it can run until +83 km / hours as a boss! Btw good video bro.
man that was an intense restoration! ty for the video! it reminds me of when we worked on my 1977 Yamaha vino 125cc, it wasn't working when we bought it(hubby is a mechanic), after a new battery, new light bulb for the headlight, buying a new carb because the old one was broken, changing the oil, cleaning gas tank, getting a new back tire I feel like we got off easy compared to your rebuild! enjoyed it very much! (my first bike was a honda 70 trail bike)
Thank you , Im glad you enjoyed my series and thank you for sharing your memories with us :)
This piece is now for a motorcycle museum, not for the road anymore...
Great job...
Thank you for your kind comment :)
loved it from beggining to end, this deserves millions of views
Thank you very much for you comment :). Lets hope enough people share it to get it to a million views that would be awesome :)
I had a C50 for my first ever bike, but an absolute pleasure watching a 90 being restored! Look forward to hopefully seeing more bike rebuilds!
Brilliant nothing more than you can say, thank you for sharing it with us all....
You’ve done a wonderful job, motor museum standard, but I had to ride one for work and without the clutch I never felt safe in emergency braking. Give me my Bandit every time.Well done👍
As a guy who first "big" bike was a Honda C70 I really appreciate the workmanship that you put on this resto.
Thank you very much :)
Work of art. Your attention to detail is 2nd to none. Awesome rebuild to watch from start to finish.. Thank you for sharing your upload.. best wishes..👍😁
Well done, That may be the best Honda restoration I have seen.
I was just thinking the same, the best restoration I have ever seen, great job, and how it really should be done
Great video, brilliant restoration of a wonderful little machine, I would love one in that condition. 👍🇬🇧
This was an excellent job. A work of love, knowledge and patience. Take a bow !
Just watched this back to back videos (too much time on my hands being retired) and i must say it was a pleasure to watch a guy with such talent, well done you sir, im trying to do a c70 but definitely not to that extent, but ive learned quite a bit from this series, simple things (now ive watched this series) that i was finding difficult and pulling my hair out over, so a huge thank you and a great deal of admiration for your skills
Hi , Thank you for your kind comment and im glad you found my videos useful for your own project :)
Hi, Thanks for sharing this video. I only saw this video in the series but it was great to see this restoration. Nicely done!
Love it, hope you’ll do another series
There will be another BIG project coming next year ;)
@@RRCRestoration Can't wait!
@@RRCRestoration Can't wait either!
What a great job. This is the dream hobby.
It looks better than new bike. VERY good restoration!
Thank you very much :)
I'd much rather have his than a new one from the factory!
I restored an early C50 a few years back , brings back memory's..you have done a fantastic job..
Thank you, Im glad you enjoyed it. Real fun bikes to work on i hope you had as much fun building yours as i did building mine
What a cracking build. I really enjoyed that. Nat Geo and Discovery channel need to take a look at how rebuilds are done.
HONDA CORP. must give u a great present for that job you made .
Haha even a nicely worded E-mail from them would be more than enough of a gift :)
@@RRCRestoration Send them the video if you can and i bet you will get a response.
Cheers
Dont forget to check out my ever growing video library - ua-cam.com/channels/KWkhqAHjW4x2oRK_yzpxlA.htmlvideos
Wonderful restoration. I do hope you can fix the crack in the fairing on the right hand side.
Thank you, I plan to get a brand new fairing for it from Honda as there are a few imperfections on the fairing that i just cant live with not when the rest of the bike is as clean :)
@@RRCRestoration See, a true perfectionist.
Inspiring and mesmerising to watch. Well done that man. Result is fabulous 👌
Excellent job, great video. Can't believe I binge watched this series... On a Honda C90 of all things. Lol.
I had the Honda SS50 as a sixteener. This reminds me of the tinkering I used to do as a ham fisted 16 yr old lol. Just goes to show how hardy these Honda engines are and how easy they are to work on. Well done that man.
Thank you very much and im very glad you enjoyed the series :) I'd love to restore an SS50 at some point :)
@@RRCRestoration we're waiting for it👍
Happy new year
"The Power of Dreams" Nicely done! :)
What a beautiful noise :-) My neighbor had one of these and this brings back so many memories...
Haven't seen so many nuts and bolts in my life...these days everything is hold together with cable ties :-(
Excellent restoration! Great job! The only thing that I’m curious about is why you didn’t do the complete upper? Like new piston, rings, bored and/or honed cylinder, etc? Anytime a cylinder is removed the minimum should be new rings and a hone job I would think. Otherwise excellent work! Keep them coming. I really enjoyed this rebuild!
What a fantastic work! Bravo! A clean and safe work environment that produced a sleek and beautiful result.
congratulations job well done they actually look better than the ones from the factory the finish is excellent,and thanks for not putting horrible music!saludos desde mexico,,
noise is better than music.
Agree 100%. The lack of rubbish music make these videos much better.
Agree ;)
Original sound efect!!
@@hafizany yes i like it
I agree too
the best restoration work I have ever seen!!! Great! you should keed this series!
Incredible man! That was super fun to watch.
I had the Honda 50, fifty years ago, and this took me straight back there. loved watching the rebuild, brilliant work.
Glad you liked it :)
Wow, this is the best! Really awesome restoration video of an awesome motorcycle! Watching this is very therapeutic! Thanks for sharing!
Just one Word, BEAUTIFUL!!!
This was a great series, I really enjoyed it. Great work.
Thank you, Glad you enjoyed it :)
Found my next project..thanks man..really inspiring..i'm from malaysia btw..really like all the detailed that you put in..really2 enjoying this project..keep your videos coming..

Azrel Tsukahara good job

Azrel Tsukahara
Im in Malaysia too. Notice his respect for tools, attention to small things and never stupid mods that have ruined so many old Hondas in Malaysia.
Brilliant job! Amazing attention to detail and your organization and cleanliness is second to none. Really impressive.
Thank you, Glad you liked it :)
The best bike rebuild I’ve ever seen. Fantastic job.
Thank ytou very much :) I have another full restoration in the pipeline for this years big restoration ;)
Parabéns pelo resultado da Honda90!!!
Ótimo trabalho de restauro!!!
Aqui no Brasil chamamos de Honda Dream...
Olhei todos episódios, muito boa qualidade!!!
lol I've noticed a couple besides the brake cable. I would have put a washer before I put the cotter pin on the pegs. But all in all. Excellent job
The washers under the split pins are there in the before photo, but missing in the finished photo. I think there maybe one missing from under the kick stand split pin too.
Never get bored of watching videos of ur channel mate...😉
Eres el mejor restaurador que he visto nunca enhorabuena y continúa con tus proyectos saludos
Others have already said all I can say about your skills and dedication. I can only agree with all of it. One suggestion - I've learned that when you put new hand grips on the handlebars, instead of a lubricant, splash the grip with plenty of rubbing alcohol. It'll slip right on, then within minutes the stuff will dry and the grip is anchored in place. Keep up the great work.
I wonder how proud he is that he wore the same gloves throughout the entire build...
IDK about anyone else but I'm impressed¡! LoL
Fantastic job mate. It looks and sounds amazing.
Thank you very much :)
Good job
Like if this serie was great!
Excellent
"Great" is an small word to describe what you've done, Mister.
Youri van Leussen. I have moto c. 70. I. Sale for you
Absolutely perfect. I don't know that I would have done anything different. Maybe polished the wheel hubs, but I can live with the media blasted look. Very very nice indeed... Thumbs Up!
Thank you for your kind comment :)
Amazing and beautiful work sir! Better than a factory build!
Thank you very much :)
Fabuloso! Belíssimo trabalho! Magnífico!
excellent work, congratulations
Show 👏👏 !!! Fantástico, gostaria de ver uma restauração de uma cros agora!! Parabéns
Enjoyed all six vids! Great to see it finished & running well. Excellent thorough Job 👍
Thank you, Im so glad you enjoyed the series :)
To me this is like watching an artist paint....The Honda 90 is by far my most loved motor bike ever...I know the bikes every nut and bolt...fantastic..
Thank you for your kind comment, Im glad you enjoyed the restoration :)

Watching that informative restoration of your C90 Honda Cub was as entertaining and enlightening as actually getting to ride it. Museum quality piece. Thank You so much for sharing the "Bringing-Back-to-Life" of this Fabulous and historically important example of true mechanical genius. Greetings from Ontario, Canada.
Last time I rode one of these was 2-up in the mid eighties from Paignton to Dartmoor & back 'shrooming! Brought back some memories! Especially the last shots! Beautiful!
