Something Failed, let’s find it! Transmission Analysis.

Well I now understand the damage.

I expect I’ll find a bent 5th gear fork when I get it out tonight.

It’s consistent with the visible gear damage and with the symptoms after the failure. I was going into 4th, it ground bad with the false neutral, then I pulled clutch and tried to upshift again.

If the 5th or 1st/4th fork were bent enough it’s very possible it slid the 3/4 input gear over to engage 5th with 4th still engaged, which would explain the one sided 3rd output damage and corresponding 4th gear damage.

Now the question really is why.

Drum
Quickshifter
Circlip

One of them is the devil.

I would put a third of your budget into more medical insurance
 
Quick shifter plus reversing the normal shifting linkage so you can stomp the shifter whether the gears and dogs are in time or not!!
That's my bet from what I know so far

What are the kill times in m/sec on you PCV speedshifter table?
Have you used the search function on this board regarding gear box shimming?
 
1-2: 85ms ( I never use it 1-2)
2-3: 80ms
3-4: 75ms
4-5: 70ms

I haven’t explicitly searched for shimming yet no.
