I believe 105 is the stock main jet size for the CA models.

Not neccessarily. The PO may have replaced the stock exhaust. Or... Maybe they bought a different set of carbs that happened to be from an EXUP bike.
Just checked - The CA & 48-State bikes ALL had the 107.5 main jet from the factory. It was the starter jet that was smaller on the CA model (50). Since your starter jets are 52.5, they are likely 48-state carbs. Another possibility is that your bike came from a higher altitude (think Denver, CO, etc.) and was therefore jetted with smaller main jets.
