I have a 2007 xb12r it has 1650 miles on it and the rear tire won't hold air. I looked over the tire and can see no nails, screws, holes or defects. I am afraid to take it to the local dealer, because I will not see the bike for who knows how long,I don't trust them to be honest about the problem and the area i live in seems to be shy on mechanical type people. No other shops will look at it without just replacing the tire do to insurance reasons...blah blah blah. So before I dump this bike that I just love to ride and by some 5 year old jap bike does anyone have any idea what I should do?
