Not that you need me to validate but I think you’re on the right track. It’s most likely a shift selector spring, worn selector fork, or weak detent wheel spring.
I guess the hope at this point is not the fork because then it's a split case and missing a couple months of the track season.
Have you done a yoyodyne before? Much different than the manual shows for a factory clutch?
Everyone's help is very much appreciated. I'm going to start ordering parts tomorrow (ordered the Sato spindle support tonight).
