25 years of streetbike experience on a variety of bikes and I agree with Markv and Jarhead. You can plug a tire and have it work fine within reasonable limits. I have plugged my own tires and, more importantly, I have plugged the tires on my wife's bike. I put thousands of miles on a CB1000 with a plug. My wife's old Sporty got another 10K with a plug before it wore out (no weight and no horsepower, go figure).
My last flat was at work and a Beemer rider lent me a kit that inserted mushroom style plugs from the outside. It's a gun that forces them in and it works like a charm. The hole is sealed from behind with adhesive and from the sides (through the tire) with pressure and adhesive. I ran out and bought the kit the next day. The one I use is by Stop-N-G0. They have a website and sell through major distributors.
