Hello Bill, When you say your aircraft was "upgraded" to the fixed tricycle landing gear, what was it upgraded from? If the aircraft ever had the standard KR-2 retractable landing gear installed, it is not eligible for operation by sport pilots no matter what it's current configuration is. In order to be eligible, the an aircraft must be originally certificated and continuously operated within the FAA definition of a light-sport aircraft (LSA). So if your aircraft was originally equipped with retractable gear, it can't be made eligible to be operated by sport pilots.
The other issues with the KR-2 are maximum level-flight speed and clean stall speed. Both of these speeds are too high according to the published "factory" KR-2 specifications. While it's not impossible that your aircraft might actually perform within the LSA definition with regard to these speeds, the FAA will go by the factory specs unless you have very detailed documentation to support your claim that your aircraft does indeed meet the LSA definition. Hope this helps! Let me know if you have further questions.
