Stock weights are the 8FP-00 which are 67.8 base grams and include the 3 heaviest rivets that Yamaha offers.
Does anyone have experience with the 8FN-00 weights which are 75.3 grams.
I am trying to load my clutch to get my rpm's down.
It also looks like the profile is different and maybe applying more force at midrange.
Thanks for your input.

What kind of mods do you have that you need to add more weight? What primary spring is in and what secondary spring do you have in?
