I'm looking through the Malossi catalog that came with my variator. From what I can decipher you need part# 29 9605. That is a set of the 3 different strength springs (green, red, & blue) for the original Agility clutch. The green is the weakest, blue the strongest. The set of clutch springs I used are not Malossi, but they also list as green, red, blue. They say the green is +15%, red +30%, and blue +50%, I'm not sure if that is the same % on the Malossi springs, but the colors are the same and in that order. Right now I have the green +15% in my scoot.
