It's a tuff call, but if you decide to plug it, just takes several rides at moderate speeds, and check the air pressure often. You can park the bike in a puddle, and look for tiny air bubbles, too. Nobody wants to throw out a tire with only 3000 miles, but some holes just don't plug very well. Some holes are just a slit, while others are a sizeable tear. Worth a try, I would say,
but at the same time, I would be ordering another tire, just in case. Gonna need it sooner or later anyway. Good luck.
