I recently picked up a 2011 r3r and have had similar neutral issues. Correct me if I'm wrong but went to adjust the lower lock nut. On this bike adjusting the lower portion only seemed to matter on the lower locking nut, the middle portion doesn't move as it is a fixed piece. Am I wrong or missing something. Needless to say I just kept doing small single turn adjustments at the handle and seemed to have found a good spot.
It there is any weight onit forward or backward it won't shift.
If just sitting there just release clutch a quick small amount the bike moves a bit and then go to neutral
