well the bearing went out on mine. the black piece that holds the bearings apart poped out and all he bearings was rolling around freely. luckily we got the bearing out from the out side. Instead of tearing the motor apart.. going to the local buell dealer and picking up the parts tomarrow.
Not to jack your thread, but on the subject of bearings, read about Hybrid/Ceramic bearings that you can purchase. Don't use them personally, but will when needed. I understand they roll much better & will easily outlast conventional bearings.
