Hmmm... not good. The basket mounts on a bushing, which in turn goes over the shaft. Once the nut is off, the whole assembly should slide off very easily. If it's not doing that, then that implies that maybe it got bound up when you were doing your full throttle wheelie/immovable object stop. First make sure that it is not a gear engagement issue. You could try an inspection mirror , but at this point, if I were you I'd consider taking off the entire right cover (like in my second link above) to get a better look at things and before taking any drastic measures like forcing it off. If you do take off the cover, remember about the LEFT HAND NUT at the top of the KIPS advancer shaft and be sure to support the shaft when loosening it.
