The effect will be 0.5 – 1% what you probably don’t even feel.
Also the polini sp exhaust on a 50ccm is not good. Better is to put a different exhaust on:
-,Leovinci
-,Proma circuit
-,Polini top one

Ah, I see then I won’t touch it.
Well, I’m going faster than my friend that has a polini top one 🙂 so its works fine for me
