Thanks for the reply. How can I tell which one I have? By the VIN?
Here's a pic of my bike:

The "C" indicates a Cali model. The only difference is the main jet, the fuel tank and the canister..
Yours appears to be a 49-state model.
It really makes no difference as long as you're not ordering a main jet or a fuel tank. Virtually every other part is identical.
EDIT: The Cali carb has an extra vent fitting. Other than that and a bigger main jet there is no FUNCTIONAL difference in carbs. They're interchangeable.
