So if I go with the 'run-it' consensus, that would essentially mean that
I have a hard time believing that I was stupid enough to overlook something that simple, but I cant say it hasn't happened before.
So here's what I'm gonna do;
Ima put in the new parts, and install the shifter arm and lever, and take another video running it through the gears again.
I would love for it to not be a bad fork, but my gut is still telling me it is.
I'll be back shortly...
was right, and I tore this thing down for nothing.

From a ex Yamaha R&D guy I've talked to, the transmissions in the 4 pokes are very weak, and they had to give up starting them in gear on the dyno because they tended to explode. Personally, my '07 has gone through 2 transmissions. The 4th to 5th fork bends slightly, and doesn't travel the gear far enough, taking out the cogs. That is a $800 parts rebuild. Not to give you bad juju, just sayin'.
I have often wondered how it held up so well considering it is really just the same and as the 250 two stroke and gets "hit" much harder than the two stroke ever would on each successive power stroke. in this case, ones would a heavier flywheel get the extra hit when changing gears.
I am not convinced any of that has anything to do with shift forks, other than the natural reaction of the gears themselves trying to separate dog from socket under force. In the higher gears where the gears are closer to the same size and torque amplification at it's smallest you would think the separation forces would be at their weakest as well. (ever notice they don't place the lower range gearsets in the center of the shafts?) But the force goes somewhere, and bent forks have always shown up more by popping in and out in the middle ranges for me. On the 5 speed yamahas and Honda 4 strokes I have had, it has been 3rd gear that pops in and out the most, as they age.

I was in 3rd when I crashed. And to be honest, I had been taking this thing to the track and treating it poorly, meaning I only use the clutch when I start out, so I wont be surprised if I bent a fork. I'm an aggressive rider/driver and tend to beat the shit out of all my vehicles (and my body).
I have never been called conservative, and like you I just use the clutch to keep it from stalling. If you learn not to rev an engine to the point it is losing power the clutchless shifts are no harder than a clutched shift all else being equal. I have transmissions as old as you are that still work fine. Did you run that one yet?
Thats funny. I'm just being a wishy-washy biotch right now. I'm out in the shop, got all the new parts installed, goes through the gears like it did in the video, thought I had it figured out, determined/thought it was a bent shifter arm (not hitting the stator cover) but hitting the protective plastic cover for the front sprocket (which is now gone). Took the arm, threw it in a vice, gave it a few quick whacks in the general opposite direction, put in place lower than I think it was beforehand, and now I'm getting it stuck in between gears again, but then found out the shifter doohickey was off the other doohickey thingy, and that I need 3 arms.
So now I'm waiting for my neighbor to come over...
