Hello all,
So I'm hoping to get some info on the differences between the 606.912 and 606.920. I'm aware that the pistons on the 920 have a bit better cooling, and the rods are stronger. Other than that, what other differences do they have? Valves? Etc.

What kind of power is each engine capable of withstanding?

Valve stems are skinnier 6mm vs. 7mm (exhaust only, I think). I've heard that the cams are different, but not sure of that.
