launch techniques?

this weekend, I tried drag launches for the first time. And I failed, miserably. I tried holding the bike at 8000rpm (where the launch control for the HP4 holds at), then easing out the clutch. Paranoid over wheelieing too much, I was on Sport mode, and while it did a great job of keeping the front down without pogoing in other gears, while launching no amount of clutchwork would get me a smooth takeoff at 8000rpm - not only was I fighting the engine, but also the wheelie control and the front wheel trying desperately to reach for the sky.

I got this one piece of advice - "roll out in 1st at 2000rpm, give it just enough gas so that the front doesn't come up, and then short shift into 2nd and peg the throttle."

but I'm wondering what S1000RR-specific techniques work for getting a quick launch off the line, and what are the characteristics of drag runs in each mode? I'll need to work on this before hitting the dragstrip; with how slow I'm getting off the line, I'll be clocking 11s or even 12s, with 1-2 seconds wasted just getting the bike rolling without stalling

a skillful/expert rider will always outperform launch controls.i read in magazine tests that when launch control is switched off 0-60 times drop

My experience is that the S1000RR sucks at launches. The best technique I've been told (and I need to practice this next season) is to launch normally at about 4,000 RPM and then catch up with the other guys who've long gone.

the stock slipper clutch is the problem, you can either fit an stm or suter clutch and that will fix the problem, other than that you need to keep the revs low on takeoff untill the clutch is fully released and then tap the back brake slightly to keep the front wheel down, i short shift straight away as soon as the clutch is out

Is there any way to keep the lift assist and turn off traction control? What about with the hp calibration kit? Only reason I ask is because I do a lot of drag racing and I would love to keep the s1000rr stock length and height, since my other 2 bikes are stretched and lowered. But I can't seem to go down the track without it flipping over on me
