4gram dr pulley

[dwint51]

i just wanted to tell some people a few things that made a world of differance.i have a performance variator 1500 rpm clutch and torque springs and stage 6 pipe and a bbk 70cc.i just hit 250 miles on the bbk kit and was dissapointed from the pipe and bbk.i had the original 5gram rollers annd was getting the same results as stock pipe and 50cc.i bought some 4gram dr pulley and i went from 7000 rpms to 9000 and now it takes off like crazy.a hill i use to go up at 35 now it says 50.dont know how accurate it is but it says over 55 on the flats.i was reading about the pipe has to get into the powerband and you can feel it pull when it kicks in.i cant believe what a differance the 4gram dr pulley sliders make from 5 gram rollers.imhappy now.it use to take lick 1000ft to hit 42 now the power is unbelieveable for a 70cc.stock air box and carb with 80 main jet on minarelli
