I am thinking about staying stock bore

in my 03 1000, i ran std bore mtc tall deck nitrous pistons...mtc is known for their extremely tough pistons. the tall deck pistons for the 1000 have .060" material added on top the piston for strength and the pin is moved up .060"

you dont have to lower compression, there is more to it than that. depending on how much your spraying and alot of other variables, like a nice exhaust cam can help ease the motor on a bigger shot, also depends on fuel and timing...

CP makes some of the best pistons available...
