Reviving a Legend: 1965 Honda CB450 K0 The Black Bomber

Reviving a Legend: 1965 Honda CB450 K0 The Black Bomber #motorcyclerewind #cb450K0
Welcome back to Motorcycle Rewind, where vintage bikes get a new lease on life, one bolt at a time. Today, we're rolling up our sleeves for a special project that's close to our hearts-a friend's iconic 1965 Honda CB450, also known as the "Black Bomber." This piece of motorcycling history has seen better days, with its engine stuck in the sands of time, but we're determined to bring the roar back to this classic.
Our journey begins with a much-needed bath, stripping away years of grime and forgotten tales, preparing the Bomber for its revival. With the bike cleaned up, we'll move on to the heart of the matter-the engine. The first step in our surgical procedure involves carefully removing the spark plugs, the silent witnesses to the engine's last breaths.
But the real moment of truth comes when we introduce the borescope to the cylinders. This high-tech peek inside will reveal the secrets held within the engine's chambers, giving us a glimpse of what challenges lie ahead. Will we find a salvageable heart ready for a second chance, or has time claimed another mechanical soul?
Join us in this episode as we embark on a journey of restoration, friendship, and the relentless pursuit of bringing vintage beauty back to the roads. It's not just about the bike; it's about the memories, the stories, and the sheer joy of breathing life into a machine that once defined an era. So grab your tools, share your thoughts in the comments, and let's get this Black Bomber booming again!
Don't forget to like, share, and subscribe for more vintage motorcycle adventures. Your support fuels our passion and helps keep the legacy of these classic machines alive.

I bought my 66 cb450 new from long beach honda in long beach california. drove it 49k miles. loved it.

[@motorcyclerewind]

That’s awesome. They’re such great bikes. Thanks for watching.

[@ErikThoeni]

thumbs up

[@motorcyclerewind]

👍

[@ErikThoeni]

I had one in the late 70s, that Bike climbs hills like crazy good. you cannot believe the tourk

[@motorcyclerewind]

Cant wait to ride it!

[@stevenlars4914]

My favorite bike ❤ I wouldn't powerwash it though because of the risc of damiging paint and other stuff. By hand is more safe and just as rewarding.

[@motorcyclerewind]

Such a great bike. Thanks for watching.

[@ErikThoeni]

It a classic I would rebuild it.!

[@motorcyclerewind]

Thats the plan. Thanks for watching

[@jeffreyhurst9552]

One of the best looking engines to ever come out of Japan.

[@motorcyclerewind]

I think so too. I have always liked these. Thanks for watching.

[@mattivirta]

but best engine have honda CB 500-750 four or new honda models honda rebell 500 engine 300 and 500 have same engine. triumph or any other not has made better engine ewer,

[@serdarcayan7691]

👍👍👍👍👍👍

[@motorcyclerewind]

Thanks for watching.

[@seanlukedado2772]

Great idea about Talking Motorcycles, looking forward to all the episodes!

[@motorcyclerewind]

I am looking forward to it. I did a bunch of them last year on Instagram. It just wasn’t the best platform to watch/listen. Cant rewind or fast forward. Let me know if you want to do one. Thanks for watching.

[@donbridgewater2988]

Looking forward to the next episode on this bike. I like ATF and acetone to unstick things.

[@motorcyclerewind]

I think I will fill it with ATF and Acetone when I drain the diesel. Thanks for watching.

[@Rollie961]

Looking forward to this 👍Love this Channel 💯☺

[@motorcyclerewind]

Thanks so much really appreciate it.

[@kalaharimine]

Clean first, agree! Better for inspection and who wants to handle dirty parts.

[@motorcyclerewind]

Agreed. Thanks for watching.

[@lovekaymax5951]

That faster than a650 triumph, a lot of history

[@motorcyclerewind]

Such a great motorcycle. Thanks for watching

[@lovekaymax5951]

I road one in 1975 it was just as fast as a Honda 750, they detuned in latter years.

[@MrGaryjames1]

pull it bore it to the max and presto a cb500 nearly! keep em coming great work.

[@motorcyclerewind]

That's a great idea. Thanks for watching.

[@gregshamieh6339]

My money is on a stuck carb float that hydrolocked that left cylinder with alcohol-goosed fuel. When fuel with high alcohol percentages evaporates, it leaves that 'It Came From Outer Space!" green slimey stuff. Don't ask how I know. ;-)

[@motorcyclerewind]

I was thinking it laid on that side and filled the cylinder. Then turned into space boogers. Thanks for watching.

[@ricardo6861]

Love this stuff🙏👍👍😁

[@motorcyclerewind]

So do I. Thanks for watching.

[@grahamwright9897]

Special indeed . I know you will look after this one.

[@motorcyclerewind]

It is a really cool bike. Thanks for watching.

[@jefftuckercfii]

Gotta say, I've never seen stuff like that come out of an engine. I haven't the faintest idea what it is. Your guess of varnished fuel is as good as any, it's just that there's so much of it. I've never seen it do that. Did you take a whiff of it, if so, what did it smell like? Don't think it's RTV, though. It's all over the place in there and there doesn't appear to be any in the other cylinder. I see you've got the first episode of Talking Motorcycles up, so I'm watching that next. Can't wait to see the next episode of The Black Bomber, too.

[@motorcyclerewind]

Definitely think it’s varnished fuel. It may have laid on its side for a while.

[@hutch73]

I’d say it depends on how much money he has to throw at it and commitment. Just the fact he has the frame, motor, and other parts is a good start. These rare bikes are special and take time unlike, say a cb350. But when it’s done the payoff is great. I’m kinda in the same boat with my 68 DT1, slightly intimidated to get into it

[@motorcyclerewind]

Agreed. I think we should look for a later CB/CL450 engine and swap it. Take some time to rebuild this one. But be able to ride it in the meantime

[@jeffreycler495]

I do half marval oil with half acetone. Let it sit for 2 weeks. Then i heat the cylinder with Map gas.When you see the vapor coming out the spark plug holes your ready to put a socket on the rotor nut amd hit it hard with a rubber mallet. Keep the torch away from the flammable acetone. I used this method on my 1974 Cb 350F that was locked up solid for 44 years it runs like a new bike.

[@motorcyclerewind]

Great Tip! Thanks for sharing. I will add some acetone and Marvels to the diesel in the case right now. Patience is key!

[@NorickFZS25]

The CB450 K0 (April 1965 - October 1968) was called the Whale in Japan and the Camel overseas due to the shape of its fuel tank.🐳🐪

[@motorcyclerewind]

Love this factoid. Thanks for watching

[@markhinde6187]

Can't wait to see the next episode, this is a special bike

[@motorcyclerewind]

Such a cool bike. Thanks for watching.

[@rhiantaylor3446]

If a bike is essentially complete, it is designed to withstand water ingress so I would wash first before you start taking a carb off or whatever. Also it means you will be working on a clean machine.

[@motorcyclerewind]

Agreed. Pus who wants a bunch of dirty motorcycles in their garage. Thanks for watching.

[@marklapirow5473]

You are getting quite a few very good bikes. The XS 650, the Laverda (American Eagle), the CB 450, the 850 T. Each one is a champion!

[@motorcyclerewind]

I am pretty fortunate with the bikes I get. Some are mine and some aren't. Lucky to have good friends with great motorcycles.

[@johnl5974]

I had a XS650, put 48+K miles on it. Needed the valves replaced, the tops had pitted . The charging system had failed. Gave the title to a guy who gave me a lift home, I'd forgotten to charge the battery at work that day. Few good memories. I think of it as a reliable BSA/Triumph, not comfortable. Mine had the step seat so, to my eye it was unattractive.@@motorcyclerewind

[@stanleybaker8707]

I would really love to come for a visit, drink a cold one(pop for me) and just talk 🏍 motorcycles,that would be awesome. 😊😊😊

[@motorcyclerewind]

Come on!!! Email me [e-mail] and let’s plan it.

[@johnl5974]

Honda didn't use torsion bar valve springs again. Any idea why? I hate seeing these old bikes ruined.

[@chrismacmahan8159]

I just the freed up a locked CB500T this past week (basically same as the 450) engine a buddy saved from being scrapped. It was apparently sitting in a backyard with no exhaust pipes. Lots of PB Blaster sprayed down the spark plug holes and into the cylinders worked for this one and always has in the past. Lots of water got into the left cylinder and rusted the piston in place

[@motorcyclerewind]

Slow and steady wins this race. Patience is key. Although I am normally short on it🤣.Thanks for watching

[@timhawkins2502]

The best I've used is 1/2 acetone and 1/2 atf.- never has failed me.

[@motorcyclerewind]

Thanks for the tip and thanks for watching.

[@jdscorpion5482]

If it wasn't hydrolocked, which it really was. Well, then after that bath, it would be ! lol🤣🤣🤣🤣

[@motorcyclerewind]

The sludge/mud in the cylinder was crazy. Thanks for watching.

[@mattivirta]

if want repair just thats bike, no matter how much parts cost, then you have new condition good bike many year, but if repair and sell no can doing.

[@motorcyclerewind]

Agreed. Thanks for watching.

[@ou7shined972]

I've got a container with petrol/diesel mix withdrawn from a customer's tank that I use for freeing up stuff that I can just let sit for days

[@motorcyclerewind]

I am going to have to make my own secret juice.

[@ridingonabudget]

Honestly, it looks like a complete engine teardown and rebuild. New internals and bearing replacement at a minimum. I think your friend may have to think seriously before launching into a rebuild of this one.

[@motorcyclerewind]

It could need lots of parts. Thanks for watching

[@klassikfahrer]

Well, I think it's like a house. If the substance is good, then it's worth restoring.

[@davidmcnamara8759]

save it :) ... it great content ;)

[@motorcyclerewind]

That's the plan! Thanks for watching.

[@nickq204]

Clean first, no doubt in my mind. I always have a semi-paranoid concern of dirt getting inside an engine or contaminating a bearing or grease.

[@motorcyclerewind]

I could not agree more. Thanks for watching.

[@Turleyswheels]

Wow could be a nice bike but going to take some money and if you can get a good one for 9k that’s a lot of work getting all the stuff and maybe only make a roller in the end unless you keep it ❤

[@motorcyclerewind]

I agree. If it were mine. I would make it a survivor. Do the engine, aftermarket seat and exhaust. Ride it as is, treat it like a rolling restoration. May take a few years to be finished but ride it the whole time. Thanks for watching.

[@shaunhardie6077]

Two words............."MONEY PIT"

[@motorcyclerewind]

The parts for this guy can be expensive.

[@shaunhardie6077]

I'm afraid this particular bike would be just too much to save, you'd never recoup the amount put into it, shame as they're an iconic machine.

[@nathanlovern5283]

If it has a good title I’d keep going with it. Do the later motors look the same?

[@stevenlars4914]

Nope. The K0 is the best looking version by far.

[@djantix1200]

Parts bike for sure.

[@ungarsdanslegarage8659]

I would put it aside and wait for the opportunity to find another one. I think it’s the cheapest way. Im doing it with my cb750 78 that needs everything. But it takes time…good luck!

[@motorcyclerewind]

May be the best idea financially. Especially with a bike that is worth some money. Thanks for watching.

[@rock-n-roll4865]

find a second bike . save that one for parts, one thing i learned there's always a few parts you cant find. like the right control with the brake perch attached for a 1970 honda cb350 super sport or a repop rear fender.

[@motorcyclerewind]

You are right, each bike has an "unobtainium" part. Thanks for watching

[@mattivirta]

if want do perfect work need first pressure wash all bike and then open carb and clean all, then check ignition .

[@motorcyclerewind]

That’s a great plan. I normally do ignition then carbs. Thanks for watching.

[@cerealtiller]

Hot Diesel Fuel down the Spark Plug holes..then warm the Engine Block with a hot air Gun until the Diesel Starts to Vapourise...then Gentle pressure ONLY on the end of the Crank with a Small Spanner or Socket. no Hammers..

[@motorcyclerewind]

Will give this a try. Thanks for sharing and thanks for watching.

[@thomashodges6104]

I think I would pull the top off and see what's inside the cylinder.

[@motorcyclerewind]

Don't believe I can pule top off without removing the engine. Thanks for watching.

[@jdscorpion5482]

That gooey thing is the Blob. Be careful, it will come to life and stalk you. The Blob, in a KZbin channel near you!😱😱

[@motorcyclerewind]

You saw the Blob crawling up my arm. This cylinder is full of crap. 💩

[@justaguy369]

That's a parts bike. Buying rebuild parts for the engine are like buying gold. (If you can source them). The juice is just not worth the squeeze for that old Honda. If you are just looking for a project to create "Content" then maybe cost isn't a factor. Cost would be a major factor for someone trying to put that bike back on the road.

[@motorcyclerewind]

We are in the same page. Normally, I take crappy motorcycles and make them run and ride as affordable as possible. The bike is worth saving. All depends on what his plans are for it. Thanks for watching.

[@SherKhan-b1kes]

The owner has to realize that things are starting at $5000, maybe even more. Once you guys have cleared that the answer will be obvious.

[@motorcyclerewind]

The prices are pretty crazy for these. They’re not making any more of them.

[@the_cafe_racer_project]

I’ve tried Marvel Mystery Oil - expensive stuff but seems to work.

[@motorcyclerewind]

I like Marvels. It works and smells good too. Thanks for watching.

[@richardhorton25]

Best penetrating oil ever is 50% Acetone 50% diesel although 50% Acetone 50% ATF runs it close

[@motorcyclerewind]

I may add some acetone to the diesel I already put in the case. It can’t hurt.

[@mattivirta]

best have rusty evapore liquid and diesel first, then oil. and if have hard rusted need use elektric evaporate elektrolyse rust off have best methor if can make, simple need only 12 volt power supply or full car battery and some hour time. then can use chemicals.

[@jeffreyhurst9552]

Acetone and automatic transmission fluid mix to free it up.

[@motorcyclerewind]

Gonna give it a try.

[@jeffreycler495]

I would not do a restoration. Make a good running bike out of it . Keep the patina. Take off cylinder and rebore , check top end, clean carbs, new tires and tubes. Neck bearings etc . The cosmetic stuff is what brings the expense up.

[@motorcyclerewind]

Thats what I would do. Make it a rolling restoration. Thanks fro watching.

[@bonniecavalcante9149]

Drain the oil put the plug back fill up with evaporust to the top 24 hours later drain again marvel oil inside I bet the engine will move

[@motorcyclerewind]

I think that is a great idea. Maybe we will get lucky🍀Evaporust worked wonders in the GPz. Thanks for watching.

[@Tomw-de3ee]

I use a gun cleaning solution made up of atf, acetone & kerosene.

[@motorcyclerewind]

I may add some ate and acetone to the diesel that's already in the case. Thanks for watching.

[@yomommaahotoo264]

Bo seat - water in thru the intake

[@motorcyclerewind]

Definitely Thanks for watching!

[@geoffreyjones2000]

That was the biggest piston booger that I have ever seen

[@motorcyclerewind]

Watching it back it was on my sleeve for a while before I saw it.🤣 Thanks for watching.

[@nathansealey6270]

Personally I’d say fix/restore it, too many old motorcycles are broken into parts & every time one becomes a part bike then thats one more classic motorcycle removed from history.

[@motorcyclerewind]

That’s might default setting. I want to save them all. Thanks for watching.

[@Travellingman32]

I use the best penetrating oil = gasoline

[@motorcyclerewind]

Gonna have to give some a try. It cant hurt!

[@alexdieudonne1924]

Dumpster!

[@motorcyclerewind]

Is there oneness your house I could throw it into!🤣 Thanks for watching.

[@mattewiegand9896]

I'd start with used motor oil.

[@motorcyclerewind]

Finally a use for the old oil laying around waiting be recycled. Thanks for watching.

[@Titan500J]

My opinion?! Make it a parts bike.

[@motorcyclerewind]

Thanks

[@paullaverty3038]

It is a parts bike in my opinion unless you have stupid money to fix it

[@motorcyclerewind]

My thoughts as well. It’s a hard pill to swallow. Thanks for watching.

[@mattivirta]

@@motorcyclerewind not waste lot money buy spare parts second bike too, this condition bike not can cost newer more than 100$ old new spare parts cost lot more if search and buy new condition parts.
