Brian,
Thank you for using Answer Army. When the PZ7234FX was first released the engine was a Kawasaki FX921 and it remains to be the same engine model. The only difference is that Kawasaki has adjusted their Horsepower ratings for their engines. The FX921 is still the same engine but now with a 31hp rating instead of the original 34hp rating. For more information about Kawasaki's horsepower rating adjustments please visit the Kawasaki website.
Thank you again for your question and using Answer Army.
