Welcome.This is a common problem on this bike.If the petcock is left on "PRI" instead of "ON" the fuel flows all the time & the float cannot hold the pressure,this is more of a problem if the carb is gummed up & dirty.The airbox and engine are flooded with fuel.You will need to clean out the air box & change the oil.When you go to start the bike you can put the petcock on "PRI" for about 10 seconds,(long enough to fill the float bowel) than turn the petcock to "ON".That way fuel only flows when the bike is running.(petcock is vacuum operated in the "ON & RES" position)

:cool:
