Is this piston next size? Picture. was created by car5car
I removed cylinder and pistons from parts bike 81 Kz1000J.
Piston has 100 on it.
Does that mean it is 2 sizes over or next size?
Cylinder is rusty and has to be bored to use. Is it out of repair limits? What is the biggest piston for sale for the bike?
I would like to know if the cylinder is usable.
Pistons have mark "art", are they original Kawasaki pistons?
Thanks.Manual says 0.5 and 1mm repair pistons.

No! 2nd o/s is 72MM.
100 means 1mm (1st o/s) = 71mm.
73MM = 1105cc .
