Last night my wife and dad and myself were going out for a ride. We did not get but 3 miles down the road and my dad noticed that my wifes bike was getting a flat tire. he stopped her so I turned around. When I looked for a cause, all I could find was a loose valve stem. Must have been loose from the factory as this V-rod only had 13 miles on it at that point. My dad went to get an air tank and in 10 minutes we were on our way. I have become accoustomed to just jumping on and riding my (trouble free) bikes. I need to take the time to look thigs over better.
