First you have got to get that 60' down. 1 tenth in the 60' is worth 2 tenths in the 1/4.what do you have to do to a stock motored 1000 to gain a sec over stock?
i went 9.20's on an 07, but we were spraying a 40 shot and making 189hp. Turning 1.60 60ft's so i am no drag racing pro.
It is very hard for me to imagine a stock motor with no spray in the 8's.
If you want to run a full second faster than you are now, you will need to do some motor work. A 1070 with gas is a good motor to accomplish this with. Although it's not all about the motor. You have to have the bike properly setup.
