depending on how much you over filled, you CAN get some oil sucked into airbox..once enough is in the airbox, it will drain out the LEFT side onto the engine, then youll see smoke and know there is issue...if you suck a bunch of oil into air box, youll see your entire LEFT side of bike and your boots soaked in oil!
if you dont see any oil drops under bike, you are probably ok Sir...you can pull tank and inspect airbox, that would be my advice.
Ensure your oil level in sight glass, with bike LEVEL is not more than 1/2 way full. Do that and your golden my man.
