Okay so on Friday I just bought a 2007 KLR650 with 625 miles on it. The rear tire and tube was just replaced along with the first service @ 615 miles by "Mega Motorsports" in Toccoa, GA. Today, 24 miles later (now @ 639 miles), while on a leisurely Sunday morning cruise around the block, the rear tire went flat, the bead seat is broken, and there is what looks like a rubber ribbon hanging out from inside the rim, apparently affixed to the valve stem, that has wrapped itself around the sprocket carrier. I thoroughly checked for any puncture or deformation of the tire (obviously), and it's perfect. The new tire is a Dunlop "tube-type" D606 130/90-17. Again this was a light on-road cruise as I'm still familiarizing myself with the bike. I ride an '07 CBR1000RR on the street, and an '07 1000RR on the track. I have a Coats 4050e tire machine we use for sport-bike tires, but I'm afraid to use it on these KLR wheels. Also I don't have any experience with tubes or "tube-type" tires. So I'm off to a bit of a rocky start here. Any advice/insight would be greatly appreciated. Thanks to all.
