I have an older tiger cat, 452 hours on it. Sadly the motor blew, just 6 cuttings after buying it. I feel the motor was on its way out as it never showed any issues. Yes oil was where it should have been becuase I was check and the air filter was brand before using it today. My questions are can you put the larger Kawasaki FX730 or is it best to stay with the Kawasaki fs651v?
