OVERREV TUNING
my brother has a 2001 & up Piaggio Zip SP scooter & we have already decided on an MHR Replica cilinder kit, what is the best exhaust for it?
my choices are the following;
MHR Replica exhaust
Yasuni R
Polini For Race3
Metrakit SP
i haven't seen a Yasuni R pipe would somebody please provide pics of that exhaust.
this will be used in conjunction with a PHBG21 carb, tuned original reedcage with Polini 0,25mm reeds, Polini OR rear pulley & belt, gear up kit & Polini Corsa crank.
of course the carters will be match ported to the cilinder but no major tuning mods, this will be for street & some occasional track use.
