I presume we're talking about parts set: 92001, 11009, 92144, 92043, correct?

It appears as though that assembly sits on top of part # 13145, "Cam-Change Drum", and probably controls the tension necessary on the shift lever to enter neutral. Again, based on appearance, it may also change the position on the shift lever where neutral is found, between 1 and 2 shifts.

It (as it appears) does not control the position on the drum (i.e. between which gears) where neutral would be engaged.

Based on the appearance of the fiche, I'm going to say it's safe to remove and inspect those parts as you see fit, but you should probably price replacements for parts:
11009 (11009-1008 GASKET,15.5X22X1 QTY:1)
92144 (92043-076 PIN QTY:1)
92043 (92144-1580 SPRING,NEUTRAL POSITION QTY:1)

Just in case something is worn/broken.

That cam (13145) is not as easy to modify as I thought.

One option is to grind off the little tang off the gear and move (cut) the inside slot back a tooth (not sure which way back is) and see if you can put neutral between top gear and first and be able to shift all the way round. (big maybe here)

DCB - if "up" is upshift, as with my Honda (and many other bikes I've ridden), the side facing to the left, or "front" on the image (look at the top of the fiche) would be upshift.

well, looking at that shift drum, it doesn't look like it will let the shift fingers go all the way around. So maybe relocate the slot so neutral is between 6th and 5th, maybe. Might just be able to grind off the tang and flip it around?

Edit: nope, flipping it doesn't help.

I'm not confident enough in my skills to go modifying the shift drum, so that's out.

I prefer binary things, either/or. I'll give the neutral bolt a twist and see what comes of it, though.
