So I am looking at a couple different RX's with similar build dates but different vin#'s and need to know how to tell if the East Troy factory put on the new rotors that corrected the manufacturing defect in the surface grind or if the original lots are on there that had the bad surface, causing the braking issues. Please describe to difference in the two or, if there is pictures someone can post of what the bad rotor looks like to compare to the new version that would be great.

Also, the factory updated the clutch master cylinder to make the clutch pull easier from what I understand. Does anyone know what they did to it exactly, to make it better? Is there a way to tell if the bikes I am looking at have that upgrade also?
