And she was running so good otherwise

[Loudo]

My '63 CB77 has been in good running condition and I've done a fair amount of riding it this summer, but the last time I rode it at the end of a long ride I discovered some funny business in the shifting department. Had the same problem this morning....upshifting from 1st to 2nd, the shift lever is hard. If I worry at it for a few seconds, I can maybe get it into second but it will immediately jump into neutral or it may bypass 2nd and go right to 3rd. Usually I can downshift to 2nd OK at that point...in fact, downshifting across the board seems fine but this 1st to 2nd upshifting is not good. It started with the occasional upshift problem, now it's more than 50% of the time. My shift lever is indexed to 11 o'clock properly.

Do the symptoms of my problem point to the shift drum/fork/roller issue I've read about on other threads in this forum? I'm hoping one of you can tell me a simple remedy involving some magic words, a potion containing an eye of newt, that kind of thing.

I had a similar symptom on mine, 38 years ago. It was a missing shift fork tang; found it in the sump!
