AOA all pw members i have a cd 70 euro 2 which have done 3500 km and after 2nd tuning 2500 km its seems to be very under power when sitting 2 persons on its and it can't go more than 50 km/h but it feels pretty good while i drive alone and touch 80km/h easily.my question is that is it ok for a cd 70 or may i need to do something to improve its pick ?
