Hello guys.I buy Yamaha aerox 70cc.And my setup is: 1.Kit Stage 6 streetrace 2.Gianelli silencer exhaust 3.Malossi variator 4.Polini clutch. 5.Carb dellorto 17.5mm with homemade revampet main jet on which I do not know his numbers.I dont ride my aerox now I have a question.What main jet i need to buy? What air filter i need to buy too. is it mandatory for me to buy carbon flaps?
I'd go for 68 in the summer, 70 in winter. If you're changing the standard air filter you'll need to increase the main jet significantly. Carbon flaps aren't mandatory but they'll make the engine more responsive and also they'll cause less damage to the engine if they break up as they normally get spat out through the exhaust.

Оk,well i need to buy original air filter and 2 main jets 68 and 70mm.Can i ride with original sponge or i buy malossi or stage 6 sponge?
