This video series features the complete restoration of a 1972 CL350 Honda Scrambler motorcycle. The videos should help anyone whether working on a cafe racer build or a full-on original restoration. I'm definitely not an expert so please refer to your manuals for proper disassembly and assembly instructions. Please leave comments if you have any questions. I'll be happy to help answer questions if I can confidently provide solutions. Again, I'm not a professional. This is my 2nd Honda motorcycle restoration and I'm learning every single day. I'd love to hear your tips if you have better ways to do things. I hope you find the series useful and entertaining. I strive to show as much detail as possible so that the videos can be used as not only a how-to resource but also a reference for the placement and original set up of parts and systems.
If you don't have one already please get a manual for your specific project. There are many available online for download for free.
Common Motor Collective, from which I source many of my replacement parts, has a fantastic resource on their website: bit.ly/CBManuals

Admirable dedication!!!
Bradley Reusch thanks, man! I think it’ll be worth the effort.
For $300 you can build a vapor blaster that’ll polish those parts with ease, i built one for my 550 and 750 restorations and its been a god given blessing for cleaning the fins on these dreaded air cooleds hahaha
I wish I had the room!
Bro i have a 300 dollar motorcycle you think i have my motorcycle left over for a clean?😂
I used extra long soft brass wire brushes with turps then cleaned, blown out with air repeated a few times! Worked a treat on my 75 cb400f resto 😊
My brushes were too wide! I need to find some like you. Thanks, Des.
I do admire your enthusiasm. I'm 67 now and have been down your road so many times since I was 14. Yep, you can work away like a mad thing endlessly; but in the end you have to draw the line under your masochistic effort. Ok, if you're building a show bike, then go for it. But getting any air cooled motor to that level....handwork will only go so far. Here in the UK you WILL get caught out in the rain. 20 miles of that will result in tears...all that work gone bad. My advice is, clean your bike regularly and enjoy it as it was intended. Hell, riding the thing gives you zero opportunity to admire 80% of your machines cosmetics....just before you pile into the back of a semi. Ask me how I know.
Valid! I get a OCD sometimes. Eventually I move on but I like to give it an honest effort.
You should use a hand held sandblaster with baking soda as media and soda blast it clean works great for everything motorcycle
Is this just over the counter baking soda?
I like your idea though in the comments there are many really good ideas with technique I just think your strategy makes sense to me and possibly less work, I'm not a pro but baking soda is in my tool box next to the duct tape and gorilla glue and JB WELD. THNX 👍 NEVERTHELESS AWESOME VIDEO
I struggled with doing the same fin cleaning as you. I went to harbor fright and bought one of there small hot steam cleaners. It comes with small brush attachments, small enough to fit between the fins and the pressure and hot water blasts out all that old grime and grease. Then went back with XL q-tips in the drill. Worked really well for me. Hope you get to where you want it brian.
Steamer! Good idea. Definitely worth considering. I’m really fighting old paint. That’s my biggest issue right now. A major PITA but I’m making progress.
Easy off cold oven cleaner works great for cleaning up your engine blocks and heads
Dude! Brilliant. I’m gonna try that.
Thanks Brian, I always pick up good tips from your videos, I am cleaning up a 72 CB450 and have faced the same issue in getting in deep between the fins, One thing that made a difference for me was to take a small file to the edge of the fins and square them off a little then go over them with a scotchbrite pad.
Andy Crabb On it, Andy. Thanks for the tip with the file. We can do this!
I love your CB350 twin videos! Never stop wrenching :) I will be the guy that feels bad for having dirty fins lol
Totally acceptable. I’m being converted towards living with dirty fins every minute. Lol.
Loosen the dirt with solvent of some sort (‘Gunk’, or acetone, perhaps) wash off with a pressure washer, spray with HT matt-black paint and polish the edges of the fins with the light application of an abrasive disc on an angle grinder.
Matt black should shift more heat than polished fins too.
You also need to watch … you’re getting a lot of abrasive particles (from wet/dry and from Scotchbrite) very close to critical surfaces while you’re using that stuff. Les in UK 🇬🇧
Try using an oscillating tool. You have to adapt a plastic fin mounted with 2 screws on a flexible bit, then by using different grades of Sandpaper (or Scotchbrite Red/Gold pads cut into strips that fit the tool) you can get down to the shiny stuff then using compound and polish it will make it shiny again. I use Sharkhide to protect the parts because polish does not last but sharkhide is a non yellowing clear coat that protects for a few years. and you can still clean the engine in the MC if need be with the same method.
That’s a great idea. I’m gonna give that a try. Need to go buy one…shucks. Lol. Thanks.
@@KeepOnWrenching Buy a cheap HF one to try it. If you love the idea then you can get a better one if you like.
Thanks Brian, I get some good ideas from your videos! I am having the same issues with my KZ1000 police motor, a lot of fins, and a lot grime, everything from toothbrushes to 1000 grit, scotchbrites. the journey is awesome!
It’s quite a journey. Darned near impossible.
Yeah man, the cylinder cleaning journey on the 4 cylinder was something else! I appreciate your videos, they helped me through a beast of an engine rebuild, which has now roared to life--what a sweet sound! I truly appreciate your friendly and down to earth approach, and humor. It's inspiring man.@@KeepOnWrenching
I have an old bike that I've been putting off cleaning the fins as it does take time, tks for the how to vid, it might just get me motivated enough to get mine done.
I hope so, Edward!
Your dedication paid off, it looks very nice, I also tend to do stuff like that manually
I got there eventually.
Love your vids Brian, i'm restoring a 71CB750 my neighbor gave me that sat in his barn for 30 years and every inch of it is nasty, your vids have helped alot! Thanks again
That’s so great to hear! I’m thinking of diving into a 750 in a future project. Good luck with your project! So awesome helping save these vintage Hondas. Go get it, Todd.
Owned a couple of them 750's.
Used to be the top dog until kaw came out with the 900.
I still have a 73 model engine with a 900 bore kit in it.
Also have a fiberglass body for one too.
Yep, those were the good old days.
Have a nice day.
I got a CB175 1967 currently working on. Some years ago I had a shop fixing and doing overhaul, the guy end up spay paint on the cylinders and gear covers etc... i hate it, now gottta remove all those. You r doing a great job
Painted engines are the worst.
Thank you for your channel, you help me! What i have found is to do something similar. I used degreaser with the scotsbrite pads
Degreaser is key!!!
There is a video by "Sweet Scoots" that shows how to make an Oscillating attachment , just like the one mentioned below.
Will check it out. Thanks.
Dang it bro your killing it. Good job. I'm one of those guys who would say look in between the jugs. So your thinking right, if you want it right
Thanks, man. It becomes a bit obsessive at times. Lol
Great idea with the scotch pad/scraper. Thanks.
It’s works in a pinch
Brian,them fins look great,dont paint,it looks like you've already done the hard work,a quick clean with fairy liquid - warm soapy water,rinse & a quick shine & there fab .
I did not paint it. Cleaned up pretty well.
All I can say, use Spray Nine Grez-Off. Put cylinder in pan, spray Grez-Off all over the cylinder, go for a beer, then take a 1 inch soft paint brush and swish of carbon, grease and dirt, it is that easy. If you can get a 4 litre bottle and just let the cylinder soak for 1/2 hour it will do the job even better.
I will try this! Thank you.
thanks, the wire polishing tools are a good idea.
Need something to get in there. Pressure washed degrease helps A LOT.
Bud iv been doing this for years now what you my friend need is a Ultrasonic Cleaner Or A Palm sander and a bucket Type the sander to the bucket, turn it on. I don't clean it like new. Works great d gracer.
I have one, not big enough! Need to upgrade!
I used an oscillating tool basically like your putty knife, but 🚫 not the blade of the tool attached a flat flexible piece of plastic with small rivets and shape the plastic pointed, round, whatever.
And as we all know clean cloth and repeat. If I do another piece soon I will try to send you a video
I bought of those. Like the idea of a custom tip. Thanks!!!
Last cylinder I did I took it to work and blasted it. Then I took it home and polished it as deep as I could. Not everyone has access to a blaster and it didn't polish it but atleast the deepest sections of the grooves looked clean.
If you have a compressor you can get a cheap sand blasting gun. The 1 with the little hopper on top. Use Bicarb soda. This is not very abrasive but cleans reasonably well.
Plan on trying that one way.
I would give a try at the car wash with the pressure hose, but when very soapy, apply a dish brush to those fins ..
To clean a 4cyl I gave it to a company that blasts dry ice. In 30 minutes everything was amazingly clean, I didn't even remove the engine from the frame. Cost me about $60.
I then polished the edges of the fins by hand.
Great job stick with what you are doing you are almost done!🙏👍👌
mike eger I think that is the plan!
sand blaster with fine grid sand or water blaster. many got those, I built one at a custom shop i used to work.
I’ve got everything to soda blasting my next build. Fingers crossed! I just need a better compressor.
No brother you are not "over engineering ". I am into ATV's, and it does get under my skin when I see that an engine has been abused by not keeping it clean and shiny (I know ATV's are made for the mud and grime). But I am a perfectionist and I love to see things clean. Those cooling fins look so beautiful when they are clean and shiny. YOU will appreciate it in the long run when you look at the engine and know that it is immaculate from top to bottom. And if just one person gets up close and personal and sees just how much detail went into shining up the engine including in between the cooling fins, you can pat yourself on the back at a job well done.
Thanks! It ended up being totally worth the effort. Beats painting them.
I always spray it down with muratic acid and pressure wash it. DO NOT leave the acid on any aluminum part more than 15 to 20 seconds! Rinse Immediately! It works quite well.
Interesting. Will have to look into that.
Great work, enjoy your videos as I recommission a 74 CB450, I noticed the same grime cleaning out the motor, I have used purple power, which has been very effective against the grime in the fins. I had some wood shims,which I use to break up the grime then use another bottle of warm water to spray out the grime best I can. One note don't let the purple power dry out it leaves a white residue. Good luck. Thanks
TheBad666m yup! I actually washed everything with purple power right away to degrease. That stuff is great. Very important to remember to rinse. Ask me how I know! It took forever to save the 1970 cb clutch side cover because I let it sit. Lessons learned. I’ll keep at it.
I cleaned my fins a little with Simple Green and a toothbrush. This is while it still was on the bike. It worked well enough for me. I was cleaning the carbs by draining the floats as well and used a little gasoline on the fins. That helped too with the greasy parts. For me it cleaned up well enough tonight. I may clean it more later. Mine is covered pretty well with full sets of fairings on my 2004 GS500F motorcycle. This was a good video. Thanks. God bless. I was thinking 🤔 a cool way of cleaning it would be with steam or nowadays even with lasers which they use for cleaning.

Thank you!!
Yes brother I enjoyed Your videos I was checking Your Vid on how to put Gas Tank Decals onfreshv paint my body guy did amazing job on custom paint and put oem Decals on my vintage CB on one side not good so I went to my mechanic shop and he had original gas tank same as my bike with Decals on it so I brought that down we are going copy OG on to my tanks and measure as well as we go hopefully 🤞😯🤞 it will come out Excellent once we are done I'm going be assistance to installing it I spend 2 years doing Cosmic Restoration Not easy on my gorgeous NOS machine to perfection mint condition and this is final touch Honda Decals are sensitive to install with body Line's and where Decals have to be placed will see how goes any suggested comments will be helpful
As far as cylinder I try see how Look with polishing several fins and look nice but I think Black Looks great with powder coat Look to it when I clean them I use simple Green ket set little while then I put scotch and white rag and clean it spray water inside rinse out dry it paint after it took few try to get paint inside you almost got get tip right up to it spray works great I paint engine as well Looks gorgeous cover all hardwares and rest parts went to Downtown with it looks Like brand new engine with same factory blend finish Looks fabulous 👌 👏 👍 😍 💖
Thank you! stripping rattlecan from the fins now!
God speed.
Very good video. I'm a picky person when it comes to shiny-ness
It takes effort but can be done!
Ok. I have had this problem and now I'm doing it for my son. I will try these brass brushes as they are affordable as break cleaning brushes for car breaks. Also engine bright spray and a water pressure hose can clean more. Lastly,high temp silver spray after an oil displacer like brake cleaner will make them look like factory new. Enjuy. Oh and tape off all the cylinder holes, oil galley ect.
Not a huge fan of painting engines but yes a pressure washer and degreaser is key.
Good work, it's called elbow grease. You also mentioned taking the engine outside and pressure washing, why not do that with that head as its already off the engine.?
Not sure. Lol. Great idea.
Easier and best way to clean and polish between fins is using a reciprocating multitool. Just take the teeth off the blade and wrap it with 3m pad, sandpaper, or cloth and polishing compound. It works 100x's faster than doing it by hand.
I have one of those! I’ll give it a try! Great tip!
Hi there Brian,I've been putting it off for a year & a half,ive never had them nice shiny fins & your method with the magic stuff (WD40) & the green billow pads, is a great place for me to start,thank you 😎😎
Go get it. It’s a major task but it can be done. Rounding off the end of the scraper helped a lot! Good luck. You got this!
As clean as possible
Thanks, man. Appreciate it.
How do you guys get bugs off the valve covers and case covers on air cooled motors? My cb1100 just bakes them right into the covers. They're factory polished and clear coated so I'm not trying to hurt the finish Any ideas?
That’s tough. That’s why I hate clear coating engine parts. You may be able to use a wet 2,000 grit sandpaper to carefully smooth them out.
You can pick up a cheep media blaster cabinet from Harbor freight or Tractor supply and soft Medea like walnut shells or soda. Be done in minutes and amazing results! Vapor blast is best but can be hard to find
I actually have one! Good call on the walnut shell
I wonder if I can grind the sharp end of a multitool blade off, then glue a scotchbrite pad to it and get acceptable results.
It’d be worth a shot. I bought an isolating tool I’m gonna try. Video coming soon!
Im having the same problem here in Britain any tips are useful
Without vapor blasting or some kind of chemical dip, I think you just need to prepare to suffer through it.
You should try making a soda blaster with a air gun. I’m having fairly good results and it’s much easier. Soda won’t damage the aluminum and it’s easy to get clean. Also go gophers
I’ve been looking into soda blasting but for this project t I’ll likely just keep it old school. Will the gophers even play this year?
You are a bit like Jack Black. Holy Buckets! Definitely vapor blast.
People keep saying that lol
So glad i read that .. Thinking the same .. Good video lol
have you tried jiff cleaning paste with a scotch pad
No but I will check it out. Thank you!
Caustic soda in boiling water. Let it soak for 10 minutes and see how clean it comes out. 😉
Interesting. Worth a shot. Thanks!
There is such a better process for this. I'll try and find the video and tag it here.
Try a 22 caliber gun cleaning brush.
That could work!
Sand blast? would that work? Like super fine sand?
I’d stay away from sand but vapor or soda would work.
I have 1968 Harley Aermacchi Sprint SS I'm restoring, fun times
Hey man, do you know anyone with a vapor hone? If it's really driving you nuts, that's a way to get the finish you are going for...
You may be able to find someone local to do it for you on the cheap.
Just heard you acknowledged that was likely the way to get the look in the closing moments of your rant. Didn't mean to rub salt in the wound! Love the content, your bike looks awesome.
Daniel Fogarty I’ve definitely done my share of google searches! :) haven’t had any luck yet. Plus corona is limiting options.
@@KeepOnWrenching check your DMs on insta!
Hay, it is Masoud. I am surprised you did ot use the engine cleaner or water pressure or steam. Thinking why not?
Worth a try for sure!
That is why a lot of people just paint them!! I’m disabled and can’t do all that physical work I’m lucky my bike is a good quality original survivor but not any where near as beautiful and spotless as your bike!
Thanks, Mike. I really appreciate that. I almost caved today and painted the darn thing. I was staring at the paint cans. LOL. A friend of mine talked me down though so here I am polishing fin edges. :)
It's to late for me comment after 2 y ago but I can say that cleaning fins are not that difficult I thought about doing my cylinder polished I decided keep it original Look it's real nice if done correctly and when I was doing came out like powder coat gorgeous its all in preparation how you go about painting them but I would stick factory Look it's best and you don't have to worry about surface Rust on polished area.
Just depends on how picky you wanna be. Blows my mind how perfect some people get them. Vapor hone would be amazing.
Is sand blasting an option before polishing?
I wouldn’t sandblast these parts as any grit and dust can do some damage. I’d worry about marring things up. Soda or vapor would be amazing. Maybe one day.
@@KeepOnWrenching I was thinking of going that route to get rid off the black engine paint in between the fins before I try to polish. Any alternative suggestions?
Andre-Guillaume Kanyinda mine had paint too. I used aircraft stipper with a puffy knife and then high pressure washer with degreaser. It’s worth the time to get it back to metal. I cry when I see people paint these engines.
Thanks and Well done...............I suppose a lot depends on the finish and cost Vs effort to get there....................What you have acheived would be good enough for most........with and eye to the final pre of degreaser/primer...............I would seriously consider bead blasting..if you can find a local, friendly nominal cost guy.
Agree. Would love to get some vapor going.
Would brake cleaner make it a lot easier?
Not sure. I’d have to try it out.
What would it cost you to have it shell/soda blasted? I mean as opposed to buying all these pads and brushes and the time you put it (which I assume is free).
I don’t know. I’d love to do that but if you don’t have the tools or budget it can be done by hand
@@KeepOnWrenching it's a small piece, so depending on how close to you the next place with a sand blasting booth, it might be worthwhile giving them a call. Should be a ten minute job for them. Of course doing it yourself gives you a sense of accomplishment, plus you get to torment your brain. Just make sure you wear eye protection when messing with wire brushes etc. on high speed tools. It's easy to forget to take precautions when in the thick of it. Using scothbright pads is a great idea. I'd combine them with wet sandpaper, using the pad as, well, padding for the sandpaper to ensure it retains contact with the fins. I'd try other bits of metal or wood too as supports for the pads. e.g. disposable wooden tongues or similar as long as they're strong enough - perhaps they are if you glue two together.
Looks like Hard Work, Maybe a Sandblaster would Speed up the Process, they Aren't Soo Dear to buy these days, You can get an Attachment for a Pressure Washer to do Wet Blasting, so there isn't Dust to deal with, a Decent Bench Grinder with a Wire Wheel is a Must Have for any Workshop, Hit it with the Bench Grinder 1st then use Scotch Pads! -Cheers👍😉🍻
would ultrasonic work?
Graig Cameron I ran the piece through my ultra sonic a few times just to clean it initially. I have a smaller unit so I had to go one side at a time. Ultimately, it had little impact as what I’m really fighting is old paint. To get it where I’d love it to be I’m going to have to just put in the time I’m afraid.
I clean my whole engine with power wash with out disassemble, first spray with heavy duty degrease let it sit for 15 min then blast with power wash + hot waters. Note : my power wash is gas OP have 3100 PSI , clean in 30 minutes
I want a hot water pressure washer.
Find someone with a dry-ice cleaner. The grain size and pressure is adjustable by button, and it would be quickly done. And perhaps change the title from "How to .. " to "How not to .. ". Since you got it apart, tougher blasting might be ok too, soda or water.
It’s really more about using what you have available to do the job. It totally doable this way. Sure, it takes time but can be done. It’d be awesome to have those other options you mentioned as options. Maybe one day. Thanks!
A good clean cylinder head is a cool looking and long lasting cylinder head
Also some oven cleaner is good start to get baked on oil and mud off your cylinder is a good idea befor wire brushing and polishing
I’ll try that next time. Thanks, Dennis.
Get some nail emery bourds. Should fit nicely
Good idea!
Just purchased a 74 Kawasaki triple barn find. The engine is nasty like yours. Wish there was a secret chemical to spray in the fins to make the sand casting look like factory. Everything else I've seen including your vid is monotonous, but looks like the only choice. Give you loads of kudos for hanging with it.
Yeah…no real shortcuts unless you can vapor or walnut blast. Still gotta degrease tho
put pin stripe over the fin ends and paint black remove tape and it looks great
That would make the edges pop for sure.
I do the same thing
It’s maddening.
dishwasher does wonders
I bet it does
A dishwash bar and pressure water washer would do this in minutes
I’d love to have a pressure washer!
@@KeepOnWrenching Yes, I was wrong to say so, wish you the bests.
Use a small sandblaster with fine media
Need a small sandblasted!
@@KeepOnWrenching you can make one for small parts for under 10 bucks. Look them up. I have one that works great for small hard to get spaces
I am going the same thing you are except I am not taking the motor out
It’s a miserable job.
Soda blasting bring it up like new
Looking into it!
Does the engine need high temperature paint after soda blasting or just left to the elements again?
Just blast it with some high temp silver/chrome spray paint.
Painting these engines just breaks my heart for some reason.
I suggest a dremel tool which can reach in those fins. Good luck my man!!!
Paul Borg that and time. Lots of time. Lol. Thanks, Paul.
You can use a brass wheel ,I have done it with success on Honda cb four.
I need to get a brass wheel for sure.
Or you can blast it with nutshells or other soft media in 10 min and have it perfectly clean :) I put few layers of thick duct tape where gaskets are
Need to get into that stuff for sure
Sand blasting is the best thing to do.
As long as it isn’t too abrasive but it can be done by hand!
@@KeepOnWrenching It's not the same as media blasting. And of course there's glass, bead, walnut, soda, etc
First use mineral spirits then paint remover then 3m wheels to scuff it! Then brass wheel then aluminum polish. easy way is clean, paint, clear coat. epoxy urethane paint not powder coat!
If the cylinders are getting honed why don't you just have them boil the whole jug. Which is what the shop would do before holding the cylinders, they usually do this overnight and the cylinder head looks brand new when they're done.
Dude, the most efficient way is sandpaper wraped around a dremel bit and go to town bro!
I’ll give that a try. Thanks!
a small sand/walnut-shell blaster will do it in 30 minutes. need decent compressor and $80. good luck.
Will look into that. Thanks!
Walnut blast! Save your hands for other things. Leaned after restoring BMW Airheads head.
Need to look into that.
BUT AGAIN IT WILL NEVER BE AS CLEAN SPOTLESS AND SHINY AS YOUR BIKE BUT IM OK WITH THAT ITS IN VERY NICE CONDITION ENOUGH FOR ME AND IT SHOWS ITS NATURAL PATINA AND RUNS EXCELLENT WHICH IS THE MOST IMPORTANT THING TO ME
I don't mind me some patina either. This CL350 has plenty of it. I'm mostly just trying to make sure all the engine parts will work well together. I'll keep at it but will do my best to not get carried away. Thanks for the support.
Hey Brian you can get as carried away as you want it’s your bike buddy
Ultrasoon...
No your not over thinking it.Dirtyness causes deterioration so it's always smarter to keep things as much as possible.
It’s just such a time suck. Worth it in the end tho!
Try some brake cleaner as a solvent. Should do a better job of lifting the crud in between.
I've heard that a few times. Will definitely give it a try. thanks!
Why not a Dremel?
I couldn’t find a head small enough.
But I’m going to spray on rust dissolver directly on rusty parts let sit for awhile rinse really good with water,,,, then spray the aluminum engine and entire bike taking the seat tank and side covers off and hit it with tire shine/clean foam and then let it drip off and I will do that process as many times as it takes
It'll clean up quick, Mike. What year and model did you have?
Burgundy with pin stripes beautiful original paint original 5593 miles all original parts except the muffler system 1979 Honda cm 400 A Hondamatic
You wanna buy it? I’ll only sell it to someone who will keep it original! Thanks 🙏 Mike
mike eger hondamatic!? I’ve always wanted to see one of those. Heard a lot about them but never seen one. I wouldn’t buy tho. Just admire. I barely have room for the two I have. :)
U can use Black Magic all wheel cleaner spray in between the fins hose it off do not buy the cleaner for chrome wheels for some reason it doesn't work!!!!!!
I’m gonna try that. Thank you.
sand jet will do
I'm always cautious using sand on aluminum for some reason.
Sand blasting ?
Just be careful with getting or using something too abrasive. Walnut shell might work tho.
Put it in an ultrasonic cleaner with some ground up diamonds and fill it with wd40 instead of water lol
Lol
Sand blaster…?
Maybe with walnut shells.
Vapor blasting, and you're done.
Wish o had a rig for that. Some of us are limited to primitive tools.
@@KeepOnWrenching It's easiest to just have it done. It's perfect in the end, and there is no mess.
@@SinnerSince1962 the mess is part of the fun sometimes. Lol. Vapor is legit nice tho!
Nassstrahlen, wenig Arbeit und besser wie neu
Yup.
sand blast it is all
Maybe soda? I’d be hesitant to use anything too abrasive.
What about; lazer cleaning!?
never considered it.
@@KeepOnWrenching idk, i was actually trying to look into options for my MT-01, then I watched your video and not sure why, this came up.. is the tech already out for consumers like us? Would be great to do this in just seconds!
sandblast it..
Perhaps.
