Are not the 550 and 700 cases the same?

Yeah that's what I thought as well.

Compare the part number of 700 cases to 550 cases.

Correction. Same stroke, but different bores. 92 vs 102mm.

SORRY I DIDN'T READ THE ORIGINAL POST WELL ENOUGH.... you are looking for used...

If its the case side that has the serial number on it. I believe you have to contact the manufacture to get it. That is what I had to do for my sons 1994 CR500 when we completely rebuilt his bike.
