Honda CBX Cylinder Repair - Welding Broken Cooling Fins EP4

Honda CBX Cylinder Repair - Welding Broken Cooling Fins! Progress is being made on the CBX restoration as I have the cylinder back from the machine shop after getting an overbore to fit .5mm oversized pistons. Cylinder 6 was the worst of them which determined the .5mm overbore to clean up the rust you saw in the last episode. I got very lucky here that I was able to avoid putting in a new sleeve on number 6.
The cooling fins were next to address as there were 5 damaged areas caused from the previous owner. I fire up the TIG welder and fill the broken areas with pure filler rod for a strong quality repair. Afterwards I shape, file, and sand the fins to a factory appearance so it will look like nothing ever happened!
Pistons were sourced from Consolidated Motor Spares:

Hello there, just watching you here from the U.K. This CBX was my dream bike around 1978ish. I would have been 16 yrs of age then. I recall my girlfriend saying one day she would buy me the CBX in silver, wow, I am still waiting! I at the time was flashing around on a CB125S 1973, quite a special and good looking bike at the time. Actually I still have it. I restored it in 2010. It had gone bang in 1979 but I had no luck fixing it. In 2010 I managed to purchase the parts I needed to get it running from America coincidently. She is a beautiful lady now in white and red candy. Just watching you with this CBX has fired my interest, you must let us see how things are progressing. Thanks for the video great! Best wishes Kevin. PS. The girlfriend is now the wife! I do on occasion remind her she still owes me a CBX!

It's impressive enough just to be a good mechanic. To be able to document it, and edit the videos to make them appealing is a job in of itself. But it's a whole other type of person who can be pelted with commentary about their career and just take it in stride. Your emotional fortitude is impressive.

So many armchair quarterbacks lol. They wear on me for sure. Glad you have enjoyed the series so far.

[@robertborchert932]

Awesome! A quick note, new subscriber. I am the original owner of a 1982 CBX-C, one of the "black" engines. Well, my CBX is "garage art" through a twist of fate. I no longer have my custom cylinder head, an absolute work of art. five angle valve seat profile, nitrided custom valves, shim under bucket, titanium retainers. Gone. But, I have a complete engine missing the head and carburetors. Micropolished crank, nitrided. The motorcycle is complete except these items. Yes, Pearl white and blue. Sorry, the Sankei original exhaust was also lost. A quick note, life is a series of curveballs. I am leaving California, and I have two Aprilias and the CBX. I would love the CBX to find a good home. Everything but the above mentioned items is perfect. Want some drool? Okay. 34000 miles. It has a custom seat made in the original profile, beautiful. This is no joke, folks. Sad part? Okay. I used to blueprint carburetors for a living. Those beautiful Keihins? Shit. Rebuilt, polished, and nestled in a custom box. Velvet lining. Oak. Brass hardware. Preserved with oil, absolutely no fuel, all new tubes. Gone. For the collectors out there, its serial number 1970. Yeah, I really miss riding this machine, I had an 81 and an an 82. Hell, I'm on a roll. The jackshaft. The CBX had a solution to the width, a HyVo chain that drove the clutch and accessories. That alternator was brilliant. The alternator was custom built, new brushes, commutator. I had a friend that built it. The CBX alternator was driven by a friction clutch. The engine could rev so FAST, it could break the alternator shaft! Irimajiri's solution was to install a clutch that allowed the engine to rev, and allow the alternator to catch up. Problem was that the commutator is radial, not axial. So, brush wear was an issue. My alternator has 110 miles on it.

Great video. It's good to see someone who is NOT Allen Millyard doing this kind of work. 'Perfect' is nice, but very few can aspire to his level. It's better to achieve an acceptable level of finish than throw your hands in the air when faced with tricky problems and negative comments. The fact that you are saving an important [ and bloody complicated ] motorcycle deserves all the good vibes that are out there. Keep up the good work.

[@BrickHouseBuilds]

Thank you much Jon! Life goals put me somewhere between Allen and Shiro of 46works if you aren't familiar. Both masters of what they do! Even though I'm doing this bike justice people will still remove any potential credit I may have the second I forget the ratchet is on loosen when I meant to tighten and have to flip the little lever. Nothing I can do about it except keep doing what I'm doing.

@@BrickHouseBuilds Yes I also follow Shiro's builds; His current project (OK last years') is one of the best - looks like you could use a new shop too!

[@rayworx]

The concept that all the cylinders must be the exact same size is untrue. The first time I attended a Honda Motorcycle Class at American Honda (it was still in Gardena at that time) they had a CB750 engine on a crate as a test engine. They'd said they had tried an experiment and oversized the cylinders from 0.25mm to 1.0mm in each cylinder. So one cylinder was 0.25mm, 2nd cylinder was 0.50mm, 3rd cylinder was 0.75mm and the 4th cylinder was at 1.0mm oversize. The engine ran just as smooth as a stock engine after some adjustments to the carbs slow speed screws. This was in 1972. Nice job on the fin fix!!

I just found your channel, and I was wondering where you were finding all of these cool bikes. It turns out our search areas overlap. I actually bought a bike in your town. Great work. I would like to make a suggestion, though. When grinding or sanding aluminum, you should wear a mask. Breathing that causes memory loss and is linked to Alzheimer's. I actually started having memory problems years ago when working in a machine shop with aluminum for 12 hours a day. Stay safe, and thanks for sharing.

[@BrickHouseBuilds]

Hey Jesse glad you found your way here! As far as a mask I wear one a lot. If I'm grinding definitely but using a rotary bit doesn't make dust so much as individual filings that don't stay suspended in the air.

Best ride I ever had - '79 CBXz. Awesome straight six sharp burble (? can't find the right word) at low revs, awesome wail when properly on song, super smooth with no vibration and awesome presentation in that fiery reddish-orange colour. Mine did not have the black stripe on the tank or on the rear bikini, so the reddish orange was beautifully dominant. When I emigrated from South Africa I had to let it go :-( - although I did consider riding it all the way from South Africa to Europe at the time (1992). Please please don't paint the engine black - that will make it look like a rat-rod, hide it's true beauty and that's not what I think you want. Aluminium (Aluminum) paint, on the bottom end, the sleeve block, and head with either proper chromed or hi-polished aluminium tappet and other covers would look simply awesome. Good luck with the build and I sincerely hope it stays your dream ride. I truly miss mine. No woman has ever come close.

I've repaired fins a few time plus other parts of the aluminum block ! Also had a H-2 750 block, that had the mounting lugs broken off. I welded them back on and drilled the mounting holes!

[@scottb8175]

Hey BJ...just some food for thought, as I still don't know if that CBX is yours or customer's. Anyway, one of the best things Kawasaki did on some of their engines was have a small area cast or machined on the crankcase/cylinder/cylinder head mating surfaces for driving in a wedge (like a medium size flat screwdriver tip) to separate the stuck top end components. The KZ1000J has one on each end of the crankcase for separating the crankcase from the cylinder. I went one step further on my KZ-J engines and machined in a similar slot slot on the head so it can likewise be wedged off the cylinder without having to beat on the head fins with a dead blow. Just picked a solid / strong place about 8 mm wide x 10 mm deep with plenty of solid material to take the pressure from the wedge being driven in. Mill out or grind out about 2 mm of the surface so the screwdriver fits in. I also sometimes run a fine thread tap through a few holes to thread the split cases, or cylinder head or block one size bigger than the studs. Then a bolt can be run in to press the pieces apart. The best location for that trick is thread where the alignment dowel pins are. I use that for a lot of crankcases that I know I will have to separate often (race stuff, two strokes, etc.). Works way better than hammering on the parts. I wish I could still weld like you - my eyes went to shit and I'm having a hard time seeing the puddle now. Aluminum is really difficult for me now. Getting old sucks!
