is it worth modding it. on my old rs125 aprilia there were loads of mods for it but they made hardly any difference at all. in the end i made it sound good and left it at that
If you do plan to run higher boost/tinker with the engine make sure you upgrade suspension as well. Mine gets a bit scary when you boot it round corners and the back end feels very skittish and likes to step out. so handling needs rectifying in tandom with power increases.
What sort of power will the starlet have after hks actuator, filter, de cat, manifold?
