Hi Evil, it’s way past that, both cases are damaged, one piston and rod are wrecked, oil pump damaged,Cylinder barrel damaged, crank journal damaged. I might salvage the cylinder head, gear clusters, that’s about it.
But all’s not lost, I’ve stopped sulking. Thanks to KK for coming up with a B engine. And thanks to Phil for the tea and sympathy. It’s gone from being a big balance bike to something resembling a motorbike. Surprised myself by getting the motor in on my own, and still having the right number of fingers and toes. Just need to connect up the electrics and see what happens.
