I recently picked up a green, ’05 America. It’s in fantastic shape, always garage kept, lots of extra chrome, and only 2000 miles. The only problem is that when I apply the front brakes, the bike bounces a bit. The feeling is similar to bad anti-lock brakes. Kinda jerky, and most noticeable at slower speeds. I thought maybe the rotor might be warped? So my question is…What could the problem be? Can I fix it my self? (I’m relatively mechanical, and have lots of tools (Dad used to be the Snap-On man)), and might it be covered under warrantee? (I’ve got a couple months left on it) but I’d rather fix it myself. Thanks for any advice.

I go to parties, sometimes untill 4. It's hard to leave when you can't find the door.
