So this weekend I had some time and I checked out the lock nut on the cable holder. The cable seemed good with a little bit of play. When the reverse button is pressed and the break is pulled the little lever below the kick start pulls up and moves freely. Regardless of the position of that lever the bike will always shift in to reverse from neutral. I tried looking in the repair manual to see if I could located what that lever is doing inside the case but I was unable to locate it. At this point I'm about ready to just live with it. However its about the last thing I have not gotten working properly on this quad since I tore it all down to rebuild so that's kind of bugging me.
