I polished the cases of my 74 Sportster, never do that again! Great video, your rebuilding the carbs episodes helped me with my friends 74 750K. A run through the ultrasonic cleaner had them looking like new.
Just a tip for the future, The easiest way to mount the engine into the frame is to lay the engine on its side and lower the frame down over it. Especially if you don't have anyone to help you. It also saves on scratching the fresh new paint on the frame. 👍
A few weeks ago I saw an older vid where a guy used Marvel Mystry oil on a rag to remove heavy aluminum oxide from an old Honda dirt bike. A wipe on and let set then wipe off. Really took quite a bit of the corrosion off. Might be something to try if you have any other AL needing clean up. Still needs polished up then but I was blown away at how much it cleaned up the rims and head and fork bodies.
Is the layer of aluminum oxide on the inside of the valve cover of concern? I did this and I'm worried about the Al2O3 breaking off in the oil while the engine is running and ruining bearings. Thanks!
If its a 750 i doubt any aluminum oxidation would harm the engine. Mine had rain water in it for a unknown amount of years before i bought it for $100. Drive mine every day to 8-9k rpm's with no problem. I have 9k miles on it to since i bought it. Want to make mine a high reving 836, so maybe i want to have some sort of problem that would make me go this route, my oil pressure is a little low.
Two great tips I grew up with in the machine shop copper wool is great for taking things off soft metal and then get some bar keepers friend it's great mag polish
Great idea with the drano. I have 79 cb750 and was wondering if you have any great tips on cleaning and degreasing the engine without damaging gaskets, seals, carburetors and electrical.
Hey Dino, is there an oil seal that goes inside of that tachometer drive mounting hole? And if there is does it go in from the inside or can you install it from the outside without having to take the valve cover off? If you have that info that would be greatly appreciated, thank you Dino!
Why not spray a clear coat to prevent oxidation later? Are there any decent clear coat rattle can products available that will handle the heat? I was thinking something ceramic like what you use for headers. I know there are products available from auto parts stores, but have no idea if they are any good or if the finish would ruin the look of all that polish work.
Aaron Fink If it gets cooked, or chemically stained, or yellowed with UV, it looks awful and is a bear to remove. More work than a simple re-polish. Also, these air cooled machines get pretty hot around the exhaust headers. I've had a hard time keeping exhaust rated paint on mine.
I was thinking of the cb the other day. When it comes down to painting the bike. I think it would be cool if you painted the frame matte black. then paint tank and the fenders gloss black. Then do a vinyl wrapp for the paint design. That way you can change out the paint design when ever you wanted
Nice job! I am struggling on few parts on my project. I do not know the cause but the covers have some sort of texture and indentations... kind of time consuming process in my situation. Enjoy your honey moon!
The primary gas released in this reaction is hydrogen. In college we would do a similar thing to generate hydrogen in a glass bottle. It gets very hot and can crack the bottle pretty easy. We used it to fill up balloons and set them on fire later. But yes, sodium hydroxide is pretty dangerous. A lot can go wrong in a hurry if you're not careful.
Yes just wipe it all down with a terry cloth rag and some soapy water. Rinse well with clear water. It's just aluminum oxide, but darker because of the chemistry. Dull light grey looking aluminum has a coating of the same thing but it's lighter in color because of how it forms slower out in the air.
Bases are great for cleaning steel and iron but they turn aluminum black. Acids will clean and brighten aluminum. I use muratic acid to clean aluminum.
Sodium hydroxyde indeed;I used to work with that stuff and I know for a fact that you can litteraly eat the aluminum using a 50/50 weight/volume concentration so be very carefull! And by the way,burning severely your skin!!
Maybe you don't realize: these Hondas came from factory with all "bare" aluminum exposed parts clear coated. I never liked this feature. After a few years it would yellow and start peeling.
When I was young we used to make drano bombs by putting those crystals in a bottle with water and tinfoil balls. Not smart. A friend got a face full of glass and drano. He was lucky he didn't lose an eye or something.
Was I the only one who found it weird you were so concerned about safety, and where to dump the bucket, but washed the striped parts off to the grass? I mean paint stripper and the little bits of paint you got off there are extremely toxic. I'm no "hey let's save the world" kind of person but whenever I use those products I never wash them off to the ground or even drain..

Nice work Dino ! The wedding was awesome, even with the sprinkles and I hope you and Lisa are enjoying your honeymoon !
Awesome to see this bike slowly progressing towards completion! :)
Great vid, worked a charm on my roached engine covers - thanks for posting!
Good to see you are pushing the safety side with PPE.
Thanks for this great tip it will help me with my CB750 project all the best Paul
Great tips Dino, ty for the early one this week. Always checking just in case.
Thank you for this video. You have helped me more to learn about my 73 cb750k3. I will be doing this in a few weeks.
Well crap. I binge watched all of these and now I'm caught up. Now I'm gonna have to wait like the rest of you.

I think it's in the video where I install the valve cover.
@@HackaweekTV yeah I already checked that video brother it's not...
Finally back to the CB750!

Nice job! I am struggling on few parts on my project. I do not know the cause but the covers have some sort of texture and indentations... kind of time consuming process in my situation. Enjoy your honey moon!
I'm just wondering, would chrome polish protect the buffed up parts against corrosion/oxidation?
Rob Robinson Yes if it has wax in it.
Are you leaving the inside of these parts just as they are coming out of the bath?
A 30/70 solution of water and classic pine sol does great as a degreaser/ mild etch to brighten up these things. Great for carburetors.
The primary gas released in this reaction is hydrogen. In college we would do a similar thing to generate hydrogen in a glass bottle. It gets very hot and can crack the bottle pretty easy. We used it to fill up balloons and set them on fire later. But yes, sodium hydroxide is pretty dangerous. A lot can go wrong in a hurry if you're not careful.
I think you mixed up what order to use your polishes .... The white is for final polish and the red is a medium cut.
I have a CB750 automatic there's 3 leavers. What are the oth 2 leavers for?
I put my engine cases in this stuff. Should the darkness be removed before assembling the engine? I'm worried about it going into the oil.
Yes just wipe it all down with a terry cloth rag and some soapy water. Rinse well with clear water.
It's just aluminum oxide, but darker because of the chemistry. Dull light grey looking aluminum has a coating of the same thing but it's lighter in color because of how it forms slower out in the air.
Thank you so much for the reply.
Hola metano Manuel tengo una moto honda cb 400 no meanda qero comparte unas de tus motos pero soi de chle jaja
Iv seen your lcd sunglasses hack really cool, have you thought of building a theatre glasses with lcd screens ?
Bases are great for cleaning steel and iron but they turn aluminum black. Acids will clean and brighten aluminum. I use muratic acid to clean aluminum.
Great work as usual.
Nice vid !
Does anyone watch some others TH-camrs that are like him doing videos on repairs and such with a lot of knowledge ? I want to see more !

Akito Yasuda. JAPAN HONDA.
When's the next video for CB750 coming? I'm addicted.
Valentin Bona Saturday morning, May 16th.
I still use progressive wet sanding, them Autosol Peek, then Mothers takes a while.
Why not use a Plastic tote so you can put the whole piece in at one time?
Looking good!
Liked before I watched it! :-D
Sodium hydroxyde indeed;I used to work with that stuff and I know for a fact that you can litteraly eat the aluminum using a 50/50 weight/volume concentration so be very carefull! And by the way,burning severely your skin!!
arkangel13th YES! Bad on the skin in concentrated form. Wear gloves!
any updates on this ?
Great job!

Great vid thanks
Here's something to remember ::::
Do as you aughta, add acid to water
May he always lie placid, who adds water to acid
I take for aluminum polish 600 waterproofingpaper and Oil.
Por favor si puedes hacer que tú vídeos sean transferidos también en español.
I start assembly my cb 750
Hey, aren't you supposed to be on your honeymoon...? :)
beau danner I am! I planned ahead for all you fans out there!
You're a gentleman and a scholar sir! :)
***** Get off youtube and go enjoy yourself :D

Do not use caustic soda on aluminium.
Sweeet!

Be sure to ventilate the space because hydrogen is generated in this reaction. Hydrogen is explosive.
Yes!
hackaweekTV : your pupils are dilated are you on drugs ?
put you safety glasses on when using the polisher
