Hello i have a 2014 SR50R and currently running the following: Stage6 Sport PRO Variator - Piaggio Polini Sport Liquid Cooled 70cc Piaggio Cylinder Kit Stage6 PRO Replica Carbon Exhaust - Piaggio Carbon fiber reeds Jasil Racing Crakshaft And running the standard air box atm with a polini filter in it currently, would it be worth getting a polini air filter but a closed one because its always rainy here and don't think rain would go well with it lol. Which one would be better and what would i have to upjet to? Polini Air Filters 46mm (Covered) Or Polini Air Filters 37mm (Covered) My jets are currently: Main jet 72 and idle jet is 32 Would it be just my main jet that would need upping and which filter would provide the best performance? Cheers! Hopefully you find my setup currently alright.
