on the 92-01 cranks what power delivery differences are there between the cranks that have the aluminum weights versus the nylon weights. the reason why i ask is i am modifying a kx250 crank to fit in my 87 tecate4 atv. it will be for mx. the crank i have is a 2000 model with the aluminum. i already have all the machine work done other than cutting the splines further back for gear alignment. then i have a 99 cylinder that is going to be punched out to 74mm and ported. i run v force reeds, 39mm pwk, and a pvl ignition ,so i already have lost a little bottom end power. probably will be using a pro circuit pipe. any suggestions or info on the crank weights or pipe to use would be greatly appreciated. by the way this will have the tecate 4 6 speed transmission with a hinson kx500 clutch basket.
