rollers
 

my minarelli came with 5gram rollers and I just purchased a koso performance variator and they recommened 7 gram and come with it.do you think that's a big difference?i also put in 1500 torque and clutch springs today and lost 3 mph and rpms went up 8000 at 40 when I use to be at 43 at 7000.i was going to purchase 6gram but these come with it

if you are going to upgrade the torque and clutch springs then 7 would probably bee a good idea, depending on your weight

I bought some 6 and fives so hopefully I will dial it in
