      Hi!
      I want to do a order tomorrow. And always used a MuVa before, but never figured out the right rolls. Drove around 5,5 Grams. Which roll set of polini would you advice for the following setup:

      Reed Valve, 19 or 21 carb, pinasco 46, calibrata, malossi gears, yellow mainspring;

      I depend to buy the first set, or maybe dont buy anyone because the Polini Speedcontrol set deliveres 4.4 & 5.6 gram rolls..

      3,5-5,1
      4,5-6,0
      5,5-7,0 Grams

        It is hard to give a generic advice about the weight of your vario rolls because this really depends on the performance of your engine. And as you probably know, even with the same setup, this can differ a lot between different engines. Besides that, it also depends on your driving preferences.

        So, I can only give you advice on the basis of my own experience and than I would go for the 5,5-7,0 grams roller set. In this range, my engines drives best often times.

        Good luck:thumb

          5.5 – 7 grammes should be fine.
          4.7 rols will need 8000 + rpm to get variator to do anything

          My guess is 6.5 gr for your setup

          De budget beun tjoener: geen geld is te duur of het werkt nog niet
