Default DTC and drag racing?

I've bought an s1000rr track bike and my first outing on it will be at a test n tune drag race meet.Can't wait for the next track day :-)
I'm running slicks and would like to spin up the rear ( burn out) to warm up the rear as cold slickas are slippery.
Q: will the traction control allow me to do this?
It also has slick mode.
Q: Whats a good tyre pressure for drag racing on a slick?

I'm very excited and a little nervous as I've herd these bikes are a bit of a weapon.

turn off traction control and put it in slick mode. start at 20psi in the rear tire and go down from there as necessary.

i wouldnt waste or flatspot the center of the trackday slick. with normal street tires it will hook and wheelie with ease..turn the t/c off and run 18-24psi in the rear and go...

Thanks for the replies,its a used slick so not worried about flat spotting it,probably ideal as plenty of rubber in the centre but little on the sides :-)
Will run as is for the first couple of runs ,then may try a strap to bring the front down,how much would you normally compress the forks with a strap?

My last run at the drag strip was on an Aprilia RSV4 and managed a 10.6,would love to be able to go sub 10 and by the sounds of it these bikes are easlily capable of it.
Although weather is looking a bit ordinary at the moment so may not get a run

i strap mine down as hard as i can.
do you have any mods on the bike? what do you weigh?
you should be able to run a 9 pretty easily.
i ran 8.9 with just exhaust/pcv and stretch/drop but i weigh 130.

if you can lower the bike through the tripples i would go around 1" as without doing the rear at the same time it makes the bike handle very unstable. if you plan on racing it competively you will need the rear lowering links. strap the front just enough to take the upward tension or spring rebound away. think of just strapping your bike down to haul but just tension it a little. being short wheelbase you will have to slip the clutch out alot to get it to 60. ive never raced my bmw but have a turbo busa and a gsxr 1000 i race...

Being an ex race bike ,it has no road gear,ohlins all round,full akro system,PC5,520 chain and track gearing,filter etc,i'm about 162lbs and have done a couple of drag races before ,my reaction time is pretty good for a relative newbie at this.

reaction time means nothing for your final time, only matters when you're racing someone else. your 60' time is going to determine the majority of your final time.
but with those mods you should be able to go low 9's!

So my time doesn't start when the green light comes on?.. so is it when I break the beam?... and the 60' is that the first 60 ft?..I'm guessing thats where you make up or lose the most time?

Well my best time was a 9:8 at 153MPH,I'm happy with that,pretty cool to have a bike that goes under 10 sec.Had a bit of trouble getting it off the line,either bogged down or wheelied like crazy,going half the length of the 1/4 with the front wheel in the air was fun ang still managed a 10:1 on that run Luv it,great bike,track day next.
