I have one bike with CC Products rear sets on it and the shaft rod on the shifter is set about 1/4" too high so I sometimes do an incomplete 1-2 shift. I'm making a new rod because the threads on the original are galled. But until I get that done, I've found that if I toe the lever up again, it goes into second. That isn't what I wanted to talk about, though.

I wanted to mention a factor that hasn't been brought up yet. Well, ME109 brought it up but not as directly as I hope to. I know some people ride these bikes like old men. They ride them as old guys used to drive pick-up trucks back in the olden days. In shifting prematurely, one will probably get crappy results. When I got my first boxer, a well used 1974 R90/6, I really liked everything about the bike except the wacky reluctant gear box. The first ride I took through a curvy road fixed the shifting issues. It still feels like it is going to break the transmission when I shift into first from neutral but when I shifted it in spirited riding, it seemed like a completely different transmission! Some higher revs will make you, the engine and the transmission happier. Of course, sensible action is assumed. I'm not advocating reckless over revving or dangerous riding.

The newer bikes with clutch carriers instead of flywheels shift like Buttah! Mine do, anyway.

If you're already aware of this, please know that I bring it up only because I think it fits into this discussion.

I also think that having the clutch properly adjusted is vital to gearchange quality.

Clutchless changes are also easy going up AND down the box (but this is much easier either with a lightened flywheel or the post 81 clutch carrier flywheel.

Best way out of a false neutral is to shift back up, then down again.
I can't seem to shift out of a false neutral without feeling like I'm grinding the shit out of the gears. And, it doesn't seem to matter whether I'm shifting up or down. I usually end up coming to an almost complete stop, then shifting.

That would make me wonder about your clutch adjustment. On my bikes, I pull in the clutch again and hit the shifter and it goes.

As mentioned in an earlier post; mostly it happens on my modified bike with CC Products rear sets and a little less often on my Cafe' Racer which has the transmission that lived through transmission hell. When I got the bike, the tranny had mayonnaise (mucho water and tranny oil) or something like it in there. On that one, the shift lever, made to work with my home made rear sets, is made from a box end wrench for the shaft part.
