So I just purchased a 2004 GSXR 600 yesterday, and on the way home I noticed a pulsating or wobbling in my handlebars. It got worse when I would brake, but it was steady throughout the ride. I lifted my bike's front tire off the ground today, and realized it was really hard to spin. It would not keep spinning even for a second when I stopped trying to turn it. I think the rotor may be warped, but they are brand new. HELP PLEASE!!!
