I want to see that bike restored. You can find plenty of Honda engines for other projects, but a classic bike in mostly one piece needs to be preserved.

[@derekpirie9188]

Fully agree. This is a gem that needs a little bit of TLC and restored back . There are other engines available for projects.

[@user-MotoZhelezki]

@@derekpirie9188 Yes, it's too beautiful to take it apart for parts!

[@danaheck9201]

Please restore! Too nice to ruin.

[@SportbikerNZ]

People always want things restored. Even if it's a pyramid of rust dust. I say break the mold. Use the engine on a lightweight kart and let it sing.

[@phoenixarizona8441]

[@junglejones]

Don't scrap it. It's a great little bike. It deserves some love. Get some new cylinder sleeves and have it properly machined. Old bikes are cool.

That thing deserves a full restore (with proper intake box)

[@swackerle]

I've literally done the same thing on a CB350F before! Lathe and all. The smoke might be from rings not seating yet, but on all 350 fours the valve guides are worn out too. They need to have .0008 to .0012 clearance with the valve stem and yes that is the right amount of zeros. Get some new guides, some reamers, an outside micrometer, and a pin gauge set and get to work guys! When they run right, they are smooth as silk and will do the ton all day long!

[@davez4172]

I second that opinion! Blaming the work you did on the lower end may be premature. It would be nice to see you guys go through that motor and identify/fix the issues. Maybe the oil burning is due to the top end. I am curious what happened to the four carbs you showed at the beginning? Didn't they fit?

[@GoldenBoyGarage]

No stem seals on the exhaust either!

There's plenty of Honda 350s around. There's no minibikes with a screaming Honda 350 engine though. Break the mold and go against the restoration cliche. Make something unique.

Restore it or café racer it. I have a 1972 CB450K5 that I bought for my youngest son that we are rebuilding it together and making it a Cafe Racer. When he gets his license he will have something to be proud to ride. Don't worry about what it's worth, just have fun.

[@ghomerhust]

70s and 80s cafe bikes were so cool looking

[@crazylare1]

Great job of saving a piece of history guys! So now what to do...? Ya know, I think that you should get a set of OEM carbs (or exact replacement style), and a set of intakes and make her run really good... then perhaps a down and dirty restore on the rest of the bike. You know, take it apart, paint the frame, clean the tank and then take all of the chrome stuff that's rusty clean off the rust and paint those parts black. I think with the green tank with everything blacked out would look cool! This is just my opinion, but ya, fix it up so it can be a finished project! Keep making great video's!!!

[@RamenPoweredShitFactory]

I think it should just get rechromed.

[@crazylare1]

@@RamenPoweredShitFactory that would be the best solution but first and formost you have to take into consideration the value of the bike vs the cost to re-chrome. I was just looking at a way that the bike can be made to look good again. I would also try to save as much of the chrome that can be saved.

[@arjovenzia]

I would agree, the black on green would look awesome. I know its not original aesthetics, but its already a far cry from factory fresh restoration. I've always been a fan of putting your own spin on restoration projects. If youve gone to all the effort to heavily modify it, why would you want it to look like it did in the brochure? Nothing against chrome, but there is something about building a one of a kind thing that appeals to me, who wants stock factory? granted tho, I do own a "I Void Warranties" T-shirt and have had some quite expensive things apart minutes after receiving them to add my own flair.

September 20 1973 was my nineteenth birthday. On that day for 1325.00 I purchased a brand new Honda cb500. Very similar to the bike you are working on. I took better care of that bike than anything i ever owned. It was a great piece of machinery It was green and black and beautiful. When I would wash it, which was several times a week, I made sure I would wash under the rear fender. The group I hung with said , “ To tell if a man takes care of his bike look under the rear fender. If it is clean you know that man takes care of his bike! I’ve owned many bikes thru the years that was my favorite one. The value of those small four bikes is rising. I would say it deserves a restoration. Just be careful to not go under water on cost versus value.

Here's a quick tip for your press, get one of the Harbor Freight 20 ton pneumatic bottle jacks. They're prettymuch a modified 20 ton bottle jack with the controls of a regular bottle jack but an extra added mechanism to operate it quickly. You can hook the jack up to compressed air and just hit a button to operate the jack and move it instead of just having to pump it by hand. The best part is that you still have the spot for the handle so you can operate it manually if you wanted to.

In the future to make it easier on you... When putting the cylinders on a 4 cylinder, put 3 and 4 near TDC first. It'll be MUCH easier to deal with 2 cylinders and their rings. A just say 2 and 3 because there's nothing in the way that way. Then 1 and 4 which are in the clear still. Easy peasy!

[@blakewixom2893]

cb350f is a pretty rare bike, It's absolutely worth restoring

[@stoddern]

First off, you can only get a true round bore and hone with the sleeves in the jug/block as the wall thickness needs the support. Then the bore gauge needs o be spun and take 3 measurements at the top and the bottom of each bore especially if the old pistons have any evidence of wear on the skirts but due to how a reciprocating engine works the pistons will egg a bore with time and cause localized wear specifically on the front and back of the wrist pins, more so on the front from the power stroke.

[@Tools2Survive]

For that washer, you could use a paper clip and string. Cheap, simple and who doesn't have a paperclip laying around? You should definitely restore it. That bike is a Legend!

That's a prime candidate for a complete restoration. The classic Honda CB Motorcycles are just super cool. Unbelievably reliable when maintained properly. And they offer damn good resale value.

When he says it's going to be a miracle if this engine runs and I hear his scoff from the background I agree with that scoff. The results of the dial bore gauge were close enough that I had no doubt. Only one concern I had was the surface of the cylinder deck possibly not making the best seal after many miles. I owned a bike exactly like that bike, same color and everything. I absolutely loved that motorcycle but owned it as a kid and didn't have the resources to keep it at the time. I have always regretted selling it to a friend from church at the time.

[@MaxsGarajMahal]

WTH John? Never heard so much negativity. Ike is still your partner? He's a good man brother. As a Master machinist, attention to the process and patience is key to success. The lathe isn't a bad way to bore a cylinder. 6 jaw chuck would have been better, however, you had a three jaw. Honing the jugs after they were back inside the jug fixture would have been the proper way to knock out the internal high spots from the lathe jaws to create a round bore. Sad this is the rings will more than likely never spin as they should and thus your smoking will never totally go away. John, lack of patience is not a good trait to show your viewers. Hope you don't lose that many. Great job Ike. Congrats Paul. Hope you and your sons enjoy assembling the mini. Thank your entire family for your service to the nation and it's inhabitants. God bless you all.

You might bring back most of the chrome shine if you use aluminum foil as a scrubber and Gojo Orange hand scrub soap with pumice as a cleaner/polish.
