Help. Is my stator bad or my voltage regulator?

Hey, i have a 2009 sportsman 500 ho carb model. Ive been getting the battery light flashing on my display when driving. I measured the volts at the battery and it is around 13-14 when idling, making me think the stator is fine, when i rev the bike up to 5000rpm the voltage will go as high as 18v. This is when my battery light will flash, when i turn the lights on or the fan comes on to give it some load the battery indictor will go away, could my voltage regulator be going, possibly over charging the battery?
