One of the most beautiful bikes ever made

33:29 and that's exactly how we did it back in the day, although we were clued up so when it started to cough we'd flip the tap 😂

I restored a 75 cb400f with a built engine and 50 over pistons. Its a great bike i dont ever want to get rid of

Took me right back to 1981 when I had to strip my 400four to get the crankcase welded up after I foolishly tightened up a crash bar bolt too much which pierced the crankcase. 😢 I couldn’t do as good a job as you’ve done with yours due to time constraints of needing the bike to commute to work, you’ve done an absolutely fabulous job on yours. Wish I still had mine, it was my first proper bike after coming from the 250cc Suzuki X7 which you could ride on a provisional license back then here in the UK. Thanks for taking the time to record your journey. 👍

Lovely little bike. Mid 70s was when I was starting out. 50 years and 50 something bikes later, I'm still a bike nut. Got to borrow a girlfriends CB400F for a few days back in the day. Fond memories of both. Great video. Thanks.

I tore my 400f motor down and then injured my clutch hand on a table saw. I'm pretty well healed now and starting to work on the engine again. Decided to remove the valves today and tackle that before reassembly of the entire engine. Great video.!

Loved this. I bought my first NEW road bike in 1977 and it was exactly like yours. Sure brought back amazing memories. Thanks.

Great work, great bike. I like the sound. Really 80’s 4 stroke, 4 cilinder sound I remember. You are also very knowledgeable and meticulous to get the details right. I like that.

A very interesting build from start to finish .Nicely captured .Good to hear your'e likely going to keep and ride this vintage diamond . After finding and resurecting it ,and with all your efforts ,it would be a tough one to move on and sell .It's a beauty to have in the stable like a thoroghbred horse that you take out for a ride every now and then just to stretch its legs . Looking forward to your next project .Cheers to you good sir .

Hi my name is Scott, this is an awesome bike! A friend of mine had a 400 super sport back in high school and I saw my second one about 30 years ago..I love small 4 cylinders and this one is so nice!!! You've done a great job putting it back on the road!! LOVE IT!!!

It was my first bike and I have kept it ever since. Exactly like yours. Same year, same colour. It starts up like new. I have a few other bikes, much bigger, but this is the only one I sit down and just look at. Luv it! Luv it! Luv it!

Great video!! My dad gave me his ‘77 CB400f that he bought brand new off the showing floor. I’ll be watching your videos as I’m going to get started getting it running. Dad passed one year ago to the day I came across your video, think dad wanted me to see it for the inspiration. It’s the parakeet yellow and has 79k on it, all put on by the family. I had to get a red tank as Dad had the original repainted and they didn’t prime it right and it rusted out, bummer. I look forward to the day I can hear that great little engine run again and take it for a ride.

Thank you for documenting your revamping of the CB400/4, its a very popular bike here in the UK The bikes of this era generally had very poor headlights, fitting an aftermarket Cibie unit was a popular mod back in the day. I found an old stock Cibie for my 1974 RD350 which transformed the nighttime riding

Very much enjoyed watching you on this project, great vlogging, and mechanical expertise, beautiful motorcycle, all the very best, thank you for sharing.

Killing it bro, always love when you drop a video

I loved these little bikes so much i owned two of them back in the eighties, you could pick them up for a reasonable price back then! Well done on your restoration, a great job.

I subscribed because of this bike. I love these small Honda fours, both the 400 and the earlier 350. To me the engine is the best sounding of all of the Japanese for cylinders. Anyway, it's one of my Grail bikes and I appreciate all of the content on it. Thanks!

One of their best. That thing will drive round the world without fault right now if you wanted to..

This bike sounds like 2 stroke heaven. I am privileged to be a subscriber to your channel. It's going to blow up.

An epic ride

Excellent video as always.

Great vlog… I’ve got a 1978 CB750 F2 that I’m just putting back together, so the carb tuning was really useful. Keep up the great work. Roger (Gloucester England) 👍

Your video is everything I could ever hope for, having sold my CB400f never having driven it.

Hi Sir, I live in Australia and am now 67 years old and in 1975 I bought a brand new Honda CB400F in Varnish Blue Colour, I had for about a year and then traded it for a new 1976 Honda CB750/4 ( K6 Model ) so your video brought back some memories, thank you for posting it

Well that brought back memories, same year and identical paint scheme to the one I had in 1980, I sold it for £500 in 1982 and the person that bought it still has it!, I remember it as being incredibly smooth and quick back in the day, I’m guessing I’d regard it as smooth but not quick were I to ride it now, still a very pretty design, nice job 👍👍👍👍

You might want to replace the handlebars with the low-rise handlebars from the earlier models, which allow the cables to run under the tank. If you leave the set-up like it is now, it looks like the clutch cable will eventually scuff-up the beautiful finish on the tank. Great restoration! and I also really like the ride-home video! Beautiful bike!

Cool Bike! In the eighties, my friend had one just like yours. I had never seen one before or after, until your video. I am not sure how rare it is, but seems so, here on the east coast, U.S. I was crushed when he sold it to buy a BSA scrambler. The BSA was cool too, with foot controls reversed from the Japanese bikes. Love your channel! Thanks for sharing.

I dont know.how to sync carbs , that would be really good to learn. Appreciate your video , glad i found it.

I never liked the CB400 four, well until I owned one. I absolutely loved it, mind you did find it hard to find neutral at first. But when I counted the gears up and down, I realised it had 6 gears. Doh! First bike I'd ever owned with 6 gears and now they come as standard. It probably why when I first saw the CB650R I fell in love with that. Which now I think I'm going to have to get one.

Had a 400 automatic. Loved it.

Nice! I recently got my hands on a parakeet yellow F1 76’, slowly dialing it all back in. Trying to find a set of CR round slides for it because my carbs have been nothing but trouble

Great video

Sounds and looks great! Fellow Ohioan here!

Nice pair of videos on this motorcycle. Had a red 1976 café version. Much nicer than the 1977 rework, IMHO. I saw an ad in a motorcycle magazine back in the day and just HAD to have one! It took two years to find one (no internet back then) and then rode it for many years. After selling it, I found out someone torched the bike and it was ruined! Best upgrade I ever did on that bike was a pair of Fiamm chrome-grilled horns. 110dB two-tone horns always got the attention of a stray car driver! ;)

Last night I read a period road test on one of these in one of my old magazines!

you should put electron carbs on it. It will be so much better. You should hit them up and maybe they will just sponsor the video and give them to you

I find that even with cheaper gaskets after a rebuild after a couple 100 me if you torque your head bolts that will usually prevent leakage. It's one of the most common misconceptions about after rebuilding a motor is that once you have it back together everything's going to be just fine but any engine that you tear down and rebuild after a few hundred hours you should really go back and reach work all your bolts but you are definitely correct with using higher quality materials especially when it comes to gaskets but I have been in situations where I've had to use you know like Fel-Pro and just buy retorquing it prevented leakage but you must do it before it starts leaking LOL

G'day from Sydney Australia, interesting video involving some good skills to do what was needed. This popped up in my feed, I had to watch it having owned and ridden one of these in red colour some 44ish years ago, used it to commute and tour, from memory they got on the cam around 6,000 rpms and came to proper life then. Unfortunately a car over-ran a stop sign on my way to work and from out of nowhere came to a stop right in front of me at 90 degrees to me blocking the road, I hit the front steel bumper side on with the bike's front wheel and my foot while on the peg and probably the rear brake hit the car's front wheel snapping the footrest off and the bike and I went over the bonnet and the 400 cartwheeled end over end for about 110 feet down the road, fortunately the bike didn't catch up to me and land on me. Front wheel jammed in the header pipes, gauges through the top of the headlight, handlebars embedded in the tank, but the sidecovers were okay and it still started and ran fine. Insurance company of the car paid me out for the bike and deducted $50 and said keep the bike lol, they didn't pay for the Shoei helmet that was destroyed in the process though. I'm sure i still have a post-crash pic somewhere (back in printed pic days). There's a few lessons to learn in that accident, back then there wasn't a huge range of protective gear readily available so many wore used Fireman's boots, and whatever jacket that was warm. Don't ride too fast in traffic like I was doing, and always wear the best gear from the vast available range nowadays, dress for the slide not the ride as they say (now I sound like my Father). As I remember the bike they were very nimble and good fun to ride, a couple of mates had stripped-down ones and road raced them too. Your video brought back some good memories. This text started out to be short, but didn't end up that way sorry, nowadays I ride a Honda VFR1200X Crosstourer, a little taller and heavier than the old CB400, at 295kgs with a 130ish HP and same in NM of torque available from idle, it's good fun, and I have all the gear too.

had a 1978 550k loved it

It's usually a good idea to put a c-clamp through the brake piston and caliper to prevent the piston from flying out of the caliper.🤣

Nice bike my first bike was a cb 360

Yes the Go Pro shots cool Peace out

I restored a 500/4, ask me how I know but don’t use the old chain, buy new sprockets and a good o ring chain. 💪 nice job, typical Honda 4, they are cold blooded and always need to warm up before they run sweetly without choke.

Great content and enjoy your presentation. So at the end of the video you mention “new fender”. Is that the rear fender? Also could you put in some links to where you ordered some parts pls Just yesterday I picked up a 77. Needs parts. Thanks

GREAT video! What brand tires and size did you install onto your CB400Four? Thanks 🙏🏻

Nice

I hope you're going to junk the cut-off rear mudguard and replace with new. Had one of these brand new in 1978 although mine was an F2 and yours is an F1

Had blue 75 model great bike

thanks for the video,can you please tell me if your bike has only one key for ignition seat and gas cap?i just bought a barn find exactly like yours but the key was lost so thats why i was just wondering before i call the locksmith thank you very much.....

No sound

never had the pleasure of using an ultrasonic cleaner how I was taught was to take a giant cooking pot and fill it with oil and put it over a burner and heat it up my uncle had a special sauce that he called it it consisted of CRC transmission fluid and a splash of diesel any parts that were really grimy we would leave in overnight on low heat and by the next morning they would be so easy to clean and what I mean by Berner I mean an electric cooktop from a camper not an open flame just wanted to make that clear because you never know what somebody might do LOL

all hail reserve fuel mechanic

All the UK chippies think this bike is great. Well in it's day and geared for 55 mph roads it was an A OK bike. My fascination is HOW you were able to acquire the proper head gasket in Japan cause Google searches don't help. Got an ol 750 and wanted to refresh the upper end too. And 4 into 1 does seem to have 'SOME" reliable parts but not head gaskets. i use kerosene or diesel fuel to soak and clean chains like that. Degreaser in the sonic cleaner seems to weaken the o-rings.

what is that tank?

The chain ain't nothing, valves and Pistons pay attention to, as well as the clutch plates

22:24 looks like someone's butchered the rear mudguard

That is a gorgeous bike! Sounds awesome! Suggestions; the fish-eye lens is ridiculous! Lose that! And maybe choose some different music that doesn't make all your viewers want to kill themselves. This is just a terrible choice in tunes. Otherwise, a well-done, informative video!!

Dommage d'avoir enlevé le garde boue.

I had one back in ‘82…felt dated then

Good video sir. We'd like to invite you to review our air pump. How can we connect with you

03 buck deer about to come out of corn field. farm house ahead, slo down u mofo, we have 3 kids and dogs here.

ditch the music rather hear the bike..

Totally unprepared bumbling. Dreadful.

Can we just STFU with the "will it run?" bullshit?
