Try taking air cleaner off before going to far, Blow carbies with air, dont use full force I done this to mine and it fixed it you may be lucky dirty jets.

there is no difference in the motor and everything is interchangeable. the only difference between the two is the air fuel mixture settings in the carbs. California has certain EPA emissions standards the bike has to meet so the settings are set a bit leaner than other states that don't have to meet the same requirements. if you get a California model you can adjust the carb settings to be the same as a regular model anywhere else.
