I got another flat on my brand new '12 990 adventure. A couple of weeks ago, I got a flat while ridding my 990 around town. No big deal, just a freak flat. I took it to the local bike shop to get repaired (with my own heavy duty tube) for a lack of time and still preparing for an out of town work trip. I got it back, rode about 60 miles to make sure everything was good, and it was. I come back, ready to take off for a few days on the 990, and the rear tire is flat again! I'm running the stock Pirelli Scorpion tires and they have about 350 miles on them (same as the bike at this point) Any ideas as to what may be causing all the flat tires? This makes me very afraid to take the bike on the long distance trips that I bought it for. I'm very capable of changing my own tires, but if it's a constant battle, it's no fun for me.
