I finally found a task that I don't particularly enjoy...engine cleaning.
On a better note, a new carburetor body arrived. My original carb's choke mechanism was broken, so I bought another body. Alas, that too had a broken choke. Third time's the charm; this latest one is ok. It's a square bowl carb with the bowl drain, which I like. It came with most of its parts, less the slide & needle, cap, spring and tubing barb. I have all of those, sans the needle, which is coming. Both jets and the float valve are Keihin, but the main is a 102. That's right, not a 120, but a 102. I never knew there was such a thing. I'll be giving it a thorough cleaning before use, but it's presently trial mounted on the engine.
I've also straightened the bent fin.
1964 CA77 RestorationEngine cleaning... good grief, what a job. 3 sides done as best I can and the 4th about ¾ of the way there. I should finish with it tomorrow. Those battered cylinder head caps are about to be replaced with better used ones.
NOS headers arrived today; still haven't decided what to do about mufflers.
I didn't finish cleaning the front of the engine today, but plan to tomorrow. Instead, I flat sanded the engine side of the carburetor insulator, finished cleaning the carburetor and installed a new 120 main jet, new insulator o-rings, etc. I started putting together the left side, but found I'm missing the 14mm washer for under the drive chain tensioner spring. I ordered one; I won't be buttoning up that side cover anytime soon. I also finished and installed the newer cylinder head caps with new o-rings.
Right and left spark plug wire holders missing in the photo, below. They both need to be re-plated. I have other bits to plate as well and will set up my operation soon. I was also able to score a starter/winker switch. It cost dearly, but I might not see one for sale again, so I didn't hesitate. I plan on mounting the engine to the frame tomorrow or on Monday. I have no experience with that as the engine was not on the bike when I bought it. I hope to put the engine on a bike lift and scoot it under the frame, then jack it up into place. Sounds simple, but I bet it won't be. Any advice appreciated.
Looking good!
I hope yopur workshop is heated. Pretty chilly here in New York.... G

It was 63 degrees (F). I did a little more engine cleaning, mounted the sprocket in the right case and fiddled with the centrifugal oil filter. It needs degreasing. I have to mix a new batch of solution, but I got the old batch out and cleaned the tank. Did a little shop organizing too, the place was getting out of hand.
More tomorrow. Done with the cleaning with a sigh of relief. It didn't come out as good as media blasting, but I've done the best that I'm able and it doesn't look too bad. At least all of the mud and grease is gone. It could still use a good wash, but that will have to wait.
I trial fitted the engine. My plan to use a motorcycle jack isn't going to work as conceived; I'll have to modify it somehow. I'll be giving it some thought. At least I got the engine closer to the frame than it has been for many years. Back to the drawing board, but I know I'll be removing the rear brake lever and maybe the bracket for the rider's footpegs & side stand.
