I just bought a 2000 1100 Shadow Spirit. I love it. It came with the windshield and extra pipes and several other aftermarket parts and I got a great deal. It had only 7900 miles on it. I have noticed when I ride on the highway at 65-70 mph there is a vibration bad enough to rattle my teeth. I donĀ“t know if it is because of the windshield or if it is the set up (shocks). Any ideas will be appreciated.
