That is a fun watch. Anxiously awaiting the FCR type smartcarb for 4 stroke. Hoping they drop January so I can get to it this year. Will make the 525 just what I want instead of me fawning for a newer FI ktm.
So for the 2 stoke setup, how many are doing it with air fuel ratio sensors and how many are doing it by ear? Hoping to do it by ear and or spark plug color when the 4 stroke smartcarb is out, but being the way I am, would sure love to do it via a sensor and maybe have a sensor on board full time to get to see ratios in various temps and altitudes...not because I don't think the carb will auto-compensate as designed, but just because it's fun to see.
