Kawasaki FX vs FR vs FS: The Brutal Truth After 5 Years of Use

Kawasaki FX vs FR vs FS: is the commercial FX engine on your zero turn really worth the extra money? I went through Kawasaki's own factory service manual line by line, then logged 10 years of owner failure reports by the hour they happened. All three share the same 726cc block, the same bore and stroke, and the same service manual. Only four things actually change between them, and the cast iron sleeves everyone argues about aren't one of them. The difference you'll actually feel is the charging system, and almost nobody talks about it.
