How will you deal with the white frame?

A lot of masking on the motor and tedious taping, then acrylic lacquer black paint and a coat of clear.  PITA but it is a darn sure better bet that trying separate the motor from frame.  Swing arm and chain guard are painted and getting clear today.  If you break it up a section at a time, it is not to bad.  What I am dreading is polishing out the aluminum valve and side motor covers, seems like you never finish, continuous black hands and a big pile of used steel wool.  I also can't figure why the PO was running an extra condenser, mounted next to the coils, the two on the points plate are hooked up, worried about the output of the 5 OMH coils maybe??????????

Hope you aren't using steel wool on aluminum side covers, the steel wool fibers can imbed into the aluminum and later when you add moisture the steel fibers imbedded in the side covers will rust causing staining of the side covers...
Aluminum oxide sand papers and real brass wheel or brushes for bad oxidizing is what I stick too. The foam sanding pads can work well to knock a lot of heavy corrosion out of they will confirm to the surface being sanded. Ribbed areas or some complex curves can use abrasive string and abrasive string wheels...just use finer grit than normal for the later.
Be sure to wear lung protection when polishing and sanding aluminum. The stuff that gets in your lungs never comes out. A fan blowing on you directing the dust away from you and working outside can help a little bit.
Polishing aluminum is really dirty business, surprised guys who do it for a living in chrome and plating shops don't die from lung issues or other similar problems... Or at least you don't see much media print to that effect/affect...maybe it isn't linked or it is ignored.

There has been huge impacts from cultured/manmade marble engineered stones a d the guys who work with it being crippled in a very short period of time. These materials are outlawed in many countries now.

Yesterday I had been on this "Big Blue Marble" a total of 75 years, and I can honestly say I cannot ever remember a summer as hot and humid as we are currently experiencing here in Eastern Virginia.  Heat index this afternoon will be at 104 degrees and it becomes too unbearable in work much past 10am in my garage with fans only.   I did go out early this morning and continue working on a very rusty rear wheel and the equally impaired OEM shocks.  I am going to keep this one as factory as possible, the points are even staying place. so I am doing my best to bring all of the stock bits back to at least presentable. 

Rafster I appreciate your input on the steel wool, and yes with what I generally have to start with, the sanding blocks or pads along with sandpaper as the the first step to even see a finish.  I still like to use very fine steel wool mid way through and complete the process with micro fiber towels for the final buffing.  In reference to lung protection I try to remember to wear at least a disposable mask when using paints or abrasives, of course the respirator paint mask does come out when the Spraymax clear and paints come into use.  I can remember playing with liquid mercury as a kid in school and Lord knows how much brake dust I have breathed changing out brake pads and shoes through the years on both cars and bikes, and I still made it to 75. I can remember my Father's favorite saying when he was my age, " Son, I am at the point in life where I don't buy green bananas anymore".  I am going to keep plugging along and will try to be cautious, but I would also venture a guess there is a lot of iffy stuff floating around in this old beat up and scared body that I am going to let be, hopefully it will just rest peacefully for at least a couple more years.

Your improvements amaze! That wheel and hub look great and the shocks even better! Best Wishes, Happy belated B’day!

 I gave up in the heat yesterday and installed a small AC unit in the shop…..Framed and sealed the hole properly today and it’s chugging away.

Nice cleaning it up. I always love when they turn out looking well and not having to replace stuff because of rust and corrosion.

Looking at the paint on the tank with the heavy fading and oxidation I am going to have to respray to bring it back.  I searched and found the below British based company that carried candy antares red at a really good price even with shipping across the pond.  The paint arrived within five days and I shot a test piece this morning was more than pleased with the match, of course aerosol cans are my weapons of choice.  It is a 3 stage paint and I have never done a tank with black insert decals so we will see. I purchased the tank decals from 4 into 1 Honda parts and they were just a few bucks cheaper than the paint.  There are couple of dents that need working so it will be awhile, but wish me luck guys, a new adventure.....

Good luck on your tank......

What are the 3 different colors?

I recently painted my CB550 K tank and painted the black insert last, but it would have been easier if I had painted it first, as my end color required a black base.  Next time I will be more careful.

I was unsure if I wanted the black insert, that's why I painted it last, and I used 3M fine line tape on the inside of decal and it worked out ok.

Bill, here is the color I chose from 66auto:
K462 Bermuda Triangle

It's a 1K paint that came in a SprayMax can, good nozzle.  House of Kolor candy paint.  Took 3 cans for tank and side covers.  Base had to be black before I sprayed the color.

It is really amazing how small tasks can turn into major pains.  I hate the starting model year 76, big giant turn signals, looks like the bike should be ridden by the Elephant Man..... The parts bike is is a 75 so they are normal in size.  On first attempt I tried mounting them with the 75 mounting/grounding plates, fit a little loose but went on and worked.  Tested them the next day and the left signal came and went, I knew it was a ground issue because pushing the signal stalk closer to plate resulted in a good flash, released it stopped.  I tried every thing I could to tighten the metal bracket to the grab bar mount, but nothing would work. The final fix came in using the mounting plates for the big 1976 signals but the bases were larger resulting in the 75 signals not lining up with the mounting holes.  After pulling out the drill, dremel tool, assorted bits, chisels, hammers, and just about every screw driver and assorted other tool in my chest, I got the situation rectified.  I elongated the mounting holes on the mounting plate and rubber insert where the ground barrel goes through. I ended up using the grinder to remove the mounted tap on the inside of the plate so I could use a longer base mounting screw and nut. I tried to cold chisel the welded tap off but it would not give, the Japanese might have ugly arse welds, but they are strong.  I ended up grinding it off after I found my pair of old fireman gloves, it only takes me three or four times touching friction heated metal parts to realize it gets damn hot. Needless to say, after all of that I relaxed and spend a little time cleaning up the rear wiring, it is starting to resemble motorcycle a little more.  I am having fun........
