just put a set of d&d twin pipes on my 2001 zr 600 efi along with a boondocker and vforce rad valve. Just wondering if anyone has a 600 with some pipes and what clutch components they are running. Size weights? Helix? Spring? I have a bunch of stuff, I just curious on what people are running.

if you are going to use cat springs i would use red/white secondary, 58-52 helix, orange/white or yellow/white primary (depending if you want higher or lower engagement) and then play with weight until you get the peak rpms right (i think 8800 for twins??). prob something like 54-56 grams
i know d&d uses stiffer springs & more weight on their kit.
good luck
