Checked
None of the seven 650SX model years verified, which needs a check against the maker's own document, which the row names, and an engine figure; all seven name a source below.

Kawasaki numbers name the engine by its size class and are not measurements: a 550 is a 531, a 650 a 635, a 750 a 743.
