Hard to say, one of the pistons took some serious elbow grease to break free, due to rust. Could just have been parked and seized that way. The pistons are so small they freeze pretty easy on these bikes I guess.
But there does remain an unsolved mystery of two springs and a metal piece I found in the oil pan.
Poured over parts diagrams and rebuild videos but haven’t yet identified them. Seems like the perfect question for sohc4.net but their registration seems to be broken.
Still prepping the cases but will have to figure out where they came from sooner or later!
