Yeah, sounds like a load of BS to me. Here in the states, the LO206 is a stock class. Period. The blocks are sealed, and once that seal has been cut, the engine is no longer eligible for competition. It’s not like Rotax where you can cherry pick the best parts, and then have an authorized dealer reseal the engine to make it legal. So far, performance from engine to engine thas been incredibly even across the board around here.
