The points-style stator shown at photo top was removed from my Rotax 503 as part of a CDI upgrade. The engine was originally pulled from a Ski-Doo, so I'm confident of the fitment. The other two stators are most definitely Rotax, but I'm unsure of the specific model(s) involved. I'm no longer flying, so am offering all three (3) stators for a starting bid of $40 + shipping. I have no way of testing these components, but can provide measurements or ohms values if that will help you decide.
