You can see the engine looked quite corroded

I had a cb550 head that had similar dammage. In my case a previous owner had broken all the top rings, several of which had smashed out of the top of the pistonand scratched and dented the head up something chronic. They had obviously been in there, removed most of the debris, sealed up again re using old gaskets and leaving bits of broken ring in the sump and blue gaskett goo behind as a calling card. I bought thd bike taxed and tested, rode it a bit and found it was ok to ride but if stalled when hot it wouldn't restart until cold. It also leaked oil, but it wax also cheap. I only found the dammage when deciding the oil leak should really be fixed. I bunged on a decent set of barrels and pistons from a scrap engine, and re used the well scarred head. It ran for years like that, never down on power or hard to start after replacing the wrecked pistons. It eventually dropped a valve, many years later. Still have the remains somewhere.

What in the hell is that thing? Is that a worm? You must have very different worms on your side of the pond.

Unbelievable, poor bike.
