Steverino's CB77

[Steverino]

I had to take the motor partially apart this afternoon. I had to in order to replace those two studs that were twisted with fouled cap nuts. Maybe the guy that messed up the cam timing thought they would look nice since he had no engine cover. Seemingly innocent little "custom" touches like that sure can mess up a motor. Splitting the case gave me a chance to look inside. I checked all the way around the gears and they look good. No chips that I can see. Notice the splotch of paint on the mainshaft. I wonder what it means.

I turned the rotating assemblies and they felt smooth and quiet with no rough spots. Here is kind of a picture with a glimps of bearing and race.

Here is the bottom half and the two studs. sI found no cracks or troublesome shards of metal.

Good to see that you've got it apart. Those yellow paint marks, I think, are from the inspectors during manufacture, They are just marking that some important assembly operation or test has been done correctly.

You used to see it on critical things like brake rotor bolts on later Hondas.

It shouldn't really matter as your botoom case looks pretty clean but I take out those two steel oil separators at the front to just see if anything lurks underneath.... Anything that gets down there is pretty safe but it helps tell the story.

The studs arrived today so I was able to move ahead.

It's looking mighty nice Steve!

Thanks Dick
I am real happy that it's looking like a motorcycle again. I did a static timing the other day. I used my continuity tester and set the points to break right on the F's. They were set quite a bit wider than .015 so I gapped them. I am looking forward to seeing how much better it will run with the cam lined up with the crank rather than one tooth behind. Thanks for suggesting to me to take a close look at the timing Loud Mouse.
I am in a hurry to try the repro header pipes for fit. After reading what people have to say about them I have a feeling I am going to have my work cut out for me.

I was unable to find a proper tap to chase the threads out on the flange so I took a screw and dipped it in thinner and ran it in and out repeating until the threads cleared up thanks for spotting that. I appreciate everyone's help.

If I use a screw, I cut a couple of slots along the length of the thread so that it traps the crud.
