I would look for a good used tranny.
My 2006 K12S, bought brand new in detroit, had 2 trannys replaced before they got it right.
there is a later revision, maybe like number 4, you should look for the latest revision obviously.
Both of my trannys started the popping out of gear problem at about 18-20k miles.
good luck to you...It really is too bad this flaw isn't covered for like, forever. I traded my bike in with 89k miles on it, about 50k on the 2nd tranny and it was flawless. I have to believe they'll outlive the bike if designed and working properly.
