Let us take the Bench Grinder! We will have both of us put our nose on the wheel. Then for you, we will turn on the grinder before you move your nose and for me we will turn it on after I remove my nose.
Same Grinders, 2 noses and both end up running! The difference is one person can say "No skin off my nose" and the other person can say, "It make no difference to me how I "Put my nose to the Wheel".
The point is, one way puts all of the pressure in the 2 to 3/32 of the engagement point. The other way keeps pressure on the forks to help gain full engagement of 4 to 7/32 of an inch. If you have taken trans apart and watched them shift through the cycle and tried both ways while doing this, we would not be having this little chat now. Please continue to do what ever you want to do. My advice is only for people that want information that may help them take care of their equipment better than others.

I also think the oil helping assist in keeping contacting metal surfaces happy and microscopically apart in your engine/tranny, may be of slightly higher viscosity than the oil on your nose/skin cushioning the effect of the grinding wheel....

This problem could very well be bent forks, worn dogs, etc. But most of the time it is the simplest thing to fix in the world. Adjust your shifter down 1/2 - 1 inch. Then try it. Many on this board can attest that it fixed the very same problem. At first they thought I was full of it (I am, but not about this). If this doesn't fix it, then tear it apart. But 99 times out of 100 this does the trick.

First, everyone here knows I have done the rebuild as I posted to help others. Secondly, That is exactly the point,,,,,,These bikes are "RUNNING" and the gears are "TURNING"!!! ""THINK man THINK"" the big point is: Metal on Metal still equals friction and wear over time!
Me and most of the guys on this page actually shift our bikes while they are running and moving down the road underload. Not sitting idle on a bench or in a garage. This makes a big difference. As the undercut dog legs also "pull" the gears together dynamically and the resistance of initial motion of engaged teeth...etc Friction = Wear But, you "ALWAYS KNOW MORE", so your shift forks should never wear out...hahaha!!! GOODLUCK

"Rounded Dogs on Second Gear" Is usually the start of the problem and not the end. Usually the missed shifts bend the forks and in the case of the 90 & 91 Zx11, all of this was Aided by a bad "Undercut"! Good one KB

I don't disagree VH.
"just changing the shift forks" will not solve the problem alone.

I've had some jerky upshifts on my 12, but it was from lazy shifting. Just touching the shift lever, instead of poppin' 'er in there. I've never had a problem with proper,deliberate shifts.  scrossed:
Also,what do you guys think of clutchless,low rpm,off throttle upshifts?

Vince,
you are a diligent guy, but I HAVE NOT SEEN THE FORKS BEND!!!! They wear on the pads, AND rounding of the dogs???? Maybe, WAY secondary to forks with ground off tabs....
been there, done that...
