Rotor Madness FYI

1976 KZ900 LTD has dual front brakes. Now I'm reading the rotors were supposed to be 5mm. Mine are 7mm so someone switched them for the single which are 7mm. I am looking for a good set of 5mm rotors. If I can't find some I'm gonna have these drilled to reduce some weight but would like to find some good 5mm's. I have to rebuild the calipers cause of sticking anyway. Jeff from Z1 said there were two size pistons in the calipers too which I did not know. A 38mm and a 42mm. He has even heard of a few of them having one of each on a bike. So FYI check your brake pistons before ordering rebuild kits and if you have a good set of 5mm rotors give me a PM. Thanks!

why dont you just turn your rotors?or ive got a set of drilled 5mm ltd rotors here somewhere if you want to swap.
