1969* Honda CB350 K - Making It Run Again
ฝัง
- เผยแพร่เมื่อ 18 มี.ค. 2022
- 1971 Honda CB350K vintage motorcycle light overhaul with a mandatory oil change, starter motor cleanup, spark plugs, condenser and ignition coils check. Removing the tank since it is rusty inside and brings all the dirt straight into fuel petcock and carburetors. Fuel tank needs to be cleaned with sloshing around gravel or acid inside the tank. Carburetors are as expected filled with gunk and dirt. There's no battery of course and someone has swapped out the original blinkers with newer square ones which have to be replaced.
Stay tuned for future videos & thanks for watching!

Hi Donn, sorry What was lack of spark die to? Thanks
We're very dependable little machines with minimum maintenance from back in my high school years.
camshaft eater engine, and NO oil filter to catch the constantly recycling debris.
I was a mechanic at a honda dealership in the early 70s..
Honda sent a memo to every dealership service department, and parts department, to stock seven top end rebuild kits for every 10 machines that that dealership sold..
I got so fast at changing the cams, thrust washers, bearing blocks, rockers in these 350 Honda twins, that I could have a camshaft out of an engine after it pulled in before the camshaft was cool enough to hold with bare hands.. I was a flat rate mechanic, and if I could do four top ends in one day, I could make 36 hours pay in eight hours..
The issue with resurrecting an old one is, there’s a lot of “while you’re in there “parts that you should replace while you were in there, like cam chain tensioners, cam chain..
One bulletin to the mechanic/service department that I still used today during that memo from Honda. Paint the base gasket and head gasket with rust oleum aluminum paint, and put it on the engine wet during assembly. That head gasket and base gasket will never leak, and when you go to take the engine apart for the next camshaft replacement, the engine will come right apart without destroying those gaskets. I still use that same can of aluminum rust oleum paint on dry paper gaskets to this day. You don’t stir the paint, you just use the gooey paint from the bottom of the unstirred can and work that into both sides of the gasket..The gasket will never stick to either surface, and it won’t leak either
Pretty damn good, I had a 69 cb350 and it was a great bike. You just took me back down memory lane to when I was 17 years old and even now I still love bringing these old bikes back to life, thank you for giving her another chance which would otherwise be in a junkyard somewhere. Ride safe.
Beautiful bike. Memories of mine 1974 CB350K come up. On the right hand side of the motor there is an oil centrifuge on the crankshaft which the motor oil cleans from dirt. It could be that there is a lack of maintenance. Keep an eye on the dirt which is there. It could clog the oil flow.
You get access to it by 3 Phillips screws on the right motorcover as far I remember.
Greetings fom Bavaria.
Its important thing, klean it !!!
Just a tip Donn, pull the chrome cover on the other side of the head and adjust the valves. They sound kinda loose. I had 2 of these and 3 cl 350 scramblers so this is a fun blast from the past. Love your fabrication videos but this was a cool break!
Nice to give it some life back. Sounds good 👍
It’s always so cool to see these things run again. I love em
It's so beautiful to hear an engine come back to life after years of sleep 😍
You just can't beat an old Honda. A good candidate for a full restore...
i am restoring a 1976 CB125J single at the moment....
@@jakobrebeki I am jealous of you, I had a 1972 CL200 back in 1977, I miss the bike...
@@lennym1273 CL? do you mean a CB200 twin.?....
@@jakobrebeki No I mean a CL200cc twin It was a scrambler look where the pipes made a fast curve where up high in the middle of the bike horizontally, I wish it had been a CB200 that way the pipes would not have heated my leg so much or not at all lol...
@@lennym1273 just looked it up on youtube, nice looking bike....
Around 1978, my twin brother bought a brand new CB360T. I almost froze to death on it one Spring day! I had never ridden a motorcycle before and didn’t realize the windchill factor.
Honda baby. That’s why. Heck ya. Nice old ride.
She's beautiful. How have you kept her from weathering so badly?
Just give her bit of extra love from us. You deserve it. All my best wishes from Oklahoma.
i have been to Tulsa OK to help a friend (Doug) build a boat in his front garden (SV Seeker) back in April 2016 and was there for 3 weeks. one of the nicest places i have ever been to. very fond memories. i still Email most of the people i met. got to go back there sometime....
i had a 73 yamaha .. my dad got it brand new, and passed it to me when i was 16.. so i could take it to school.. this video brought back some big time memories! many thanx!
What a find!!!! Really good shape for this classic bike.
Seeing the title and thumbnail I'm like it's a Honda... it's run. My Honda motorcycle is like a hole, it just works. Put tires one it, change oil, give it gas and minor maintenance like air filter, coolant, breaks every 10 years and she's good. Hondas just work. Love the build and wow that oil plug was tight! Somebody got stupid with with it. My big oil plug has a mesh filter on it yours maybe missing not sure but I know that about mine. What a cool bike🥰🥰🏍🏍🥰🥰
I used to have a 71 Honda cb 450 dohc it was a beast. With minimal rebuild was dependable for years. I have now a 81 Honda cb 750 k that runs but still needs more TLC . but I'm just not into the restoration process as I used to be. And e bikes are so much fun now, with cardio benefits.
E bikes, electric cars/motorcycles etc; hmm. There's going to be a massive scramble for gas powered everything when main power grids fail either b/c of age and/or lack of maintenance like those seen in CA [with more already forecast], or via the fact they're prime targets during conflicts. Lets not forget the anarchists who tend to suddenly get a bee in their bonnet. With the majority of gas stations having gas powered back-up generators [b/c it's required by law], anything powered by a gas engine is gonna look real nice during those events.
I had a 71 too!.rode the crap out of it for 2 years,never did any maintenance at all.
сижу перебираю своего старого ижа . включаю видео , а там хонда 71 года , класс! посмотрел и ещё раз убедился какая всё таки ущербная советская мототехника . о такой хонде только мечтать остаётся ... видео супер !👍👍👍
The brass tubular screen is gone out of the fuel petcock and the tank crossover was good at collecting junk. Power issues can be caused by mis-setting the points. There were 2 models of engines with very different firing angles. Mine was 179 degrees and I don't remember the other, but my friend had it, and the shop used the 179 and it ran on 1 cylinder until I fixed it for him. The insulation in the starting motor was dodgy and not oil resistant. The rectifiers were inefficient and went bad often (and may have contained mercury). The neutral light switches got mangles frequently. Never saw one with original carbs that did not have holes in the diaphragm (which led to an interesting, almost "digital" power curve). A heavy keychain WILL make the ignition switch go bad quickly. Watch the brake linings. If they get too thin, it's possible to pull the cam over the top leaving you with zero brakes. Don't forget to set the valves and adjust the cam chain tensioners frequently. The most common cause of engine damage was a faulty shifter seal letting the oil out (slowly and stealthily). The swing arm would require frequent greasing which most people did not do, leading to nasty clean up (I mixed anti-seize with the grease). When the clutch pack would get thin, you could add an extra pair of plates to get it back to "new". The upper and lower steering races had a different number of balls, 37 on top, 36 on the bottom if I recall. That's all I can think of. Good luck and enjoy!
Great old Honda CB. Such an icon of the motorcycle world. Love it Donn.
Should be a fun project. Those old CB's were pretty badass back in the day, make great power for their size and were quite fast. They also loved to rev! Can't wait to see you blasting down the road with this baby!
Wow brings back some memories...I had a 350 Scrambler from that time and it was a everyday means of transportation during the late 70s to the early 80s . These bikes may not have been super fast but they was so much fun and easy to ride. I always wanted a 350k because of the exhaust running on the bottom instead of the right side can't tell you the times I got burned and cussed every time. Great change of videos keep us updated on the progress of the bike as well as the new build.
Beautiful. That's roughly the vintage of the one my oldest brother had. Took me for a ride when I was about 10. I was wearing shorts, and when we got back, when I got off, I burned the inside of my right calf on the chrome pipe. Yeah, I learned THAT lesson!
Takes me back a few years Donn, thanks for sharing with us, stay safe and keep up the great videos. Fred.
Nice looking bike. The bike is in a very good condition considering it's age. It is as old as I am. Glad that you brought it back to life👌🖒
When I saw how you handled the oil drain plug, my guessed estimate of succes raised from 95% (it is a Honda) to 99.95%.
You sir are a true mechanic.
Now I will watch the rest of the video ☺️🤝🏻🇳🇱
Pretty awesome. I had a Honda 125 was a sweet lil bike. Thanks for sharing
Wow! A blast from the past... Yours is sure in good condition for being ~50 years old. I had a 1972 CB350F that got 40mpg... it was the smallest 4 cylinder bike ever up to that time.
Gord here I had a 1978 XS 650 Yamaha 1é4 mile terror killer ,I called lol 145 mph nobody could catch me . Then one day went to the shed where is was parked and POOF stolen. Well thats life. Now I a 750 low rider 1986 Yamaha and still got to putt around . Will find my 650 y one da I hope.
Motor impian waktu masih sekolah dulu.... Ternyata ada di sana.... Hahahah
This bike looks very good for its age. I used to have one like this but sold it to a friend who had that particular bike as his first bike. Happy motorcycling 🏍
Love the vids and appreciate the detail and effort you put into everything you do. Keep on keeping on my friend.
It looks very well looked after and in good condition already
Remember those screws are JIS not Phillips. They get chewed up if you use Phillips enough times.
Great to see it lives again :-)
Been using philips screwdrivers for over 30 years and no problems. Just don't try to use the wrong size philips for the screw. Most of them work well with a #3 Phillips. Also, get yourself a hand impact for the tighter screws, even the JIS drivers chew them up. With the hand impact, you can loosen them the first time and avoid chewing them worse than they might already be. Cheers from rustbelt Alberta Canada 🙂
@@lowellfunk8974 We know rust very well. Cheers from southern Norway 🙂
I still have a 71 cb350, just picked up a 72 cb 200 with only 800 miles on it. Can't wait till I get that one running
A beast n beauty... Combined...
That typical Honda throb is music to ears.... Thanks for the video...
Very nice
Wow nice find. Had a 1973 CB350 back in the 80s, fun and reliable bike.
Alright a 70's CB cycle. I like it! I have to follow this series as well. Thumbs Up!
I'm so jealous I enjoyed riding mine it's brought back some great memories 😌
my dream bike 😭
Very Rare motorcycle in the condition it’s in.
Now that’s a score!! I would love a bike like that to commute to work on nice days.
My younger brother had a '71 CB350K and I had a '71 CB750K. Later, when I went into the Army, my brother sold his 350 and bought my 750. Those were fun days. There was an issue with the 750 though, the stock chain would stretch and jump the front sprocket upon sudden deceleration coupled with hard braking and the chain would jam up between the sprocket and the crankcase and crack the cast aluminum I had to completely disassemble my engine and take the block and case to a professional welder and have it heli-arced. After that I replaced the stock chain with a higher quality after market chain and never had a problem with it agailn.
You'd never find anything of that era in that nice shape outside of a collectors garage over here. Nice old bike!
MM77 Approved 👍🏼👍🏼
I vote for a complete overhaul/rehab project series. (She's worth it.)
Those things can run forever. They just need some love!
Love these old UJMs - I’m rebuilding a 1982 GL500 in the garage right now :-)
well done, looking good! also those filters are a good idea on older bikes that are driven less often, you can clearly see if there is rust in the tank as the filters are see trough.
Also its good idea on 4 stroke machines to use some two stroke gas in the engine before putting it away. It does not cost much to add the oil and it covers surfaces of the carbs and cylinder with some oil preventing rusting, unlike pure fuel. Less oxidation and such crap. When taken back to use just pour in normal gas and it flushes the system from the oil. Little bit extra emissions and suth but nothing major. Same apply to oil injection two strokes btw.
This was great. Thanks for posting!
Thanks for watching!🙏
That was one very stuck oil plug! Awesome video. As always.
It's in really good shape for its age. A little steel wool on the chrome and it will look like new!
Уважаю с отличный подход к делу!
I had a Honda 125 CB K, looked amazingly similar. The sound was awesome as it was a twin four stroke. Anyone not seeing it thought it was a large bike 😁
A boy and his bike, it's a love story. Is that the cute CB 350 that took you on a trip to Romania a few years ago? A very nice machine and sturdy too.
That’s awesome job 👍
Beautiful bike!
Excellent work 👍👍👍 . Thank you for sharing
Love an old Honda... This one is super clean!
That thing is in nice shape for it’s age. Nice find.
I had same year model, was a CB250 , new no problems🤠
Bought a cb250ko in 1973 in bits, it hasn't been outside my back gate since then, I rebuilt it over the years finding some parts that were missing and finally got it running some years ago before covering it up and leaving it again, put a battery on it a few days ago pressed the button and it was running within a minute thats why most of my many bikes over the years have been hondas in contrast my suzuki 1980 gsx1000et which I've owned since 1985 is the biggest pain in the arse I've ever owned fortunately my 95 cb1000 big one never lets me down
You the Best bro. I like you're work and videos 👌😍❤️❤️❤️. Best wishes from Morocco 🇲🇦
Great job, thank you brother. You are so talented
just as old as i am.. 71 is a good year i need to say
I had a bike just like that except the paint job was different! Miss those days.
It's crazy I used to ride that same bick every day back in the early 90s . Keep an eye on the coils I keeped a spare. The left was a problem child for somereason? Always got me home . Heck even an old snowmobile coil will work . Just one bolt holding it on . You're going to like ! No love it.
Those old Hondas are tough and will run forever if treated half way decent. I had a 1970`s 450 and a 750 4cyl. They were fun but dangerous. I clipped the back end of a dear going about 80 mph on a long sweep corner and just barely made it without crashing. Take care
Lovely machine!
As a kid in the 80s these were abundant and cheap. I've had a few.
Nice engine sound 💪 like it 🙂
Great choice! Rock! 👌🏻
Wow! That was definitely kept indoors!
Reminds me of my 76 Honda cl360 I had in college
A buddy of mine had one of those back in the day. He bought it new in 1971.
Looks in pretty good condition - on the outside!
I personally think that was one of the best bikes ever made and are a world of fun to ride. Points were a problem with oil on them but I think there is a felt gasket that keeps most of it out, I hope so. A bunch of nuts and bolts in the tank an put it on the paint shaker or a car wheel and left to rotate helps but usually new is best. If you are a seldom rider, fixing is best still.
Very nice bike mate 👌
Great job.
Great old bike! 👍👍
Bike is older than me; half the engine doesn’t fire, and it still starts in a couple of turns. Honda engines are dark magic.,
Nice Old Honda.😁 Good Job Dude.
Now that's a cool as bike man!
Reminds me of the CB350 I had. I put over 50,000 miles on it and then I made it into a Bobber. I traded it for a 1958 Chevrolet Fleetside pickup.
I had a mc for 14 years never changed the oil only top off it drives like when it was new 😁
I see a wicked Side Car fabrication build coming up soon! Cool score Donn! 😁
Great bike! I have one myself. Note: at 10:35 in your vid I can see that the left side intake valve adjust bolt is oriented the wrong way. The line/tick mark on the screw should be around 4 o'clock position. Yours is at around 9 o'clock. Check all 4 valve adjusts. The tick marks should always be facing outwards. So around 7 o'clock for exhaust and 4 o'clock for intake! Then set your gaps from there. Cheers
Enjoyed watching you work on the bike, new series of videos perhaps??
Dang, fav honda bike, spare me the fancy fast bs, even the cb500 four cyl.. 350 is where it's at. WANT
awesome!😃
Even though you got it running I would still give it a complete tune up with new points, condensers, plugs and plugs wires.
Congrats! 👏👏👏
Yes please! Do a restoration videos at you way! It will be amazing!
I first thought that the peace of the crankcase fell off 😆 You can change the pistons through that hole. Nice ride! :P
muy linda moto! me encanta el color, cuando vi (will it sart?) me dije, por supuesto que va a arrancar, es una HONDA! te felicito por los videos, no puedo esperar al fin de semana para verlos! SALUDOS desde Entre Ríos ARGENTINA
The oil drain plug might have been big because sometimes they put an oil filter in there. Enjoyed the video.
Very good 👍
10x, cool start!
Such reliable motorcycles... the old Hondas 👍
Stored for years? It looks brand-new!
Well, the paint anyway. The shiny bits have some character.
Nice bike 🤟🤟
