I haven't torn it down yet, but my best guess is that the cam chain jumped a tooth. One minute I was riding along without a care in the world; the next, I was going 65 mph without a headlight at eleven o'clock at night on a dark country road listening to my engine do an impression of a trash can full of gravel.
The oil is full of chunks. I found the remainder of one circlip. From what I can see, it seems like I'm looking at the remainder of a piston skirt.
Whatever caused this made enough of a sudden jolt that it destroyed the new copper advance mechanism delete from my Pamco unit. I'll hit Pete up tomorrow about buying a replacement.
Luckily, I just bought a parts bike with a fresh professional (or at least, farmed out by a known judge of quality) rebuild.
My plan is to swap that into the bike while I rebuild this engine, likely with a rephase, MikesXS overdrive 5th, and some other goodies. We shall see once I get it open.
