Just got a 2006 bullet. Not green but still quite nice .Sedate and dignified, in a noisy sort of way. But the BAD noise: When I depress the rear brake there is a grinding sound from the engine. Opened the primary hoping to find a loose tensioner. Was perfect, so not the problem. Its not in the brakes ,themselves, as I've looked at them as well/. Also this is most definitely a gear-grinding-itself-to-death sound. I was just learning to love it. Anyone have any thoughts? thanks.
