Well, my temporary change or permanent change in technique to cope with the huge clutch distance is to lift my elbows up so my hands are at an angle that allows me to quickly modulate the clutch.
If you just consider pure technique (leaving aside bike modifications), from what I've read and what I can attest to it seems the most important things to improve are the 60ft time, throttle technique (getting it WOT ASAP) & shift point. I know all the drag veterans on here are going "no shit sherlock" so obviously this is aimed at other & i'm possibly just having a rant...lol. My only advice from my limited experience so far, is practice certainly is the only way to make perfect.
Obviously if you can make these things easier through modifying the bike, then by all means go for it, but i'm one of those people that believe 'hey, if someone can run a high 9 on a stock busa with no mods (environmental factors can play a part like altitude, temperature,etc), then the cheapest thing I can do & definately most satisfying thing I can do is improve myself'
In my opinion & from what i've witnessed, most people simply cannot launch hard nor get the throttle open quick enough. Some people make the excuse that they don't have a drag strip to practice which is a cop out. There is always a dead empty parking lot where you can practice 60ft stuff. I've been using one as you only need 18m or so (60ft) to practice. Even taking a cone or something and marking the distance out, taking note of your control & stuff. This also applies to cornering, slow speed manoeuvres, etc.
Its almost as though some people stop learning how to improve their riding because they are afraid to let go of their pride and admit they are not a pro just yet. I also think years on the road is an unreliable indicator of experience. While I know people like Max & Heidi can ride the balls of the busa, I see plenty of older people on cruisers & shit who are noticably missing important skills.
If you disagree that you can improve, watch these links. They certainly made me up my game.

Everytime I start getting cocky & thinking i'm all king shit, I simply go watch some pro's again & stop & say "I need some more work" but this drives you to even higher levels. I would personally never let myself get too confident, because I also believe its one of the things that leads to an accident. I'll stop there with the mental part of things, i'm getting off track.
My only gains so far have come from constant experimenting with clutch control and launching rpms, etc & just trying and trying continually. Its hard particularly for me to try something that looks so easy and realise its not, but if I suck at something to begin with, I live & breath it till I can do it.
Sometimes I think you simply have to let the brain slowly make the new adaptations to what you are learning & not force the process. For some of you into the mental side of things, a very interesting thing as some of you may know, is when we sleep & dream, etc, the brain rehearses activities that we have performed throughout the day. So you may have found sometimes after practicing an intricate process, you wake up the next day suddenly much better at it......doo doo doo...mystery....put it too good use :-)
While I haven't hit the strip yet (hence i'm more than open to criticism if i'm wrong) I look forward to it soon.
BTW, take my advice with caution, i'm only 19
