I just put 1000 miles on my new/used K1200. While on my way home suddenly I couldn't down-shift from 6th gear. It eventually moved, but the remainder of the ride up-shifting and down-shifting were problematic. I do not see any issues with the linkage to the shift lever on the transmission. Looks like a pain to get off and back on without tearing the exhaust off. I'll change the transmission oil next and look for fragments.
