Topic: KZ 750 pistons

[vonbagh]

I would like to use  kz 750 1982 pistons (66mm) on my cb 550 four / cb 650 hybrid engine. Does anyone know how you have to modify those pistons to make them fit? Deck height and valve reliefs must be lowered but how much?

first try if you can find new piston rings
