Unhappy Popped out of gear and won't go back!

I have a 1973 honda 500 four that runs great, but I was cruising down the highway in 5th gear at average rpm's when I heard a pop, then I was stranded in the middle of nowhere. It won't go in gear at all but still runs fine. What might it be, I say maybe clutch or linkage but I know nothing. Any advice would be greatly appreciated.

Did the '73 500 four have a primary chain like the 750?

Sounds like something in the primary drive broke, a gear or (chain?)?

That, or termites.

It's probably not the clutch. I suspect something in the gear actuating system has broken. As I'm sure you've seen by now, virtually the entire trans is contained inside the cases except for the lever itself, including the primary chain. Bottom line, it's not going to be something you'll fix yourself. Better find a shop that knows the old Hondas and get the bike over there. Or if you're not dedicated to the bike sell it. If your bike is fairly intact you could probably do well on the price. People are collecting the 70's Hondas now.
