heya just hoping u can help me about this frustrating situation...
I have a 55plate aprilia rs 125 with most preformance on it and its still struggling to get to 100mph? heres a list of what i have got..

154 polini bore kit
34 mm carb
v force3 reed valves
piperx filter
cdi has been deresticted
had exhaust with cat in it but that got cut up and welded back together
power valve is set fine..and rave valve box is there.

am just wondering if it electrical as it only revs to 11,500 ,12,000 at a push with the big bore kit...ive tryed everything and spent so much money!am begining to give up on it

plez help!
