Welcome to the site !!

Are you getting any codes at the Map Switch (blinking) ?? , Do you have any history on the bike ?? , like has it sat for months ??? , how was it maintained , etc. ?? , My first guess without knowing what is going on , is going to be the Fuel Pump , which is located in the gas tank at the bottom ...... or a clogged Injector ......... Those would be my first 2 guesses ....... , but your description is a bit vauge , so without having a lot of details , it is hard to diagnose ........
