i have a 2000 kawasaki kdx 200. so far i have an fmf burley pipe and powercore 2 silencer, v-force reed cage, uni airfilter, 48 tooth rear sproket (47 is stock), a spiralmax unit (it swirls the air before entering the carb for a better air fuel mixture), and the airbox lid was removed. i plan on getting cylinder porting but am not sure what that is. is porting the same for all dirtbikes or can i have different things done to it for different power results like more bottom or more top?? and i would like to know if there is anything else i can do to my kdx to make it more powerful (im a power freak), other than boring it out or using higher compression (i still want to use pump gas (93). thanks for any info.
