Hello everybody , recently i've decided to rebuild my old SR WWW from 98 (AC) , the scooter was recently painted it looks great but the engine is dead . What i had noticed that the SR WWW it's really slow , when i have the stock exhaust good sprint but max speed 75 with sport exhaust ( leo vince zx) no sprint at all and when i say no sprint a mean no sprint and max speed 95 (5,7 gr weights)... So can you give me some suggestions what posibly can i do with it to go faster and better acceleration because now it's dissasembled completly and I want to make it fast and reliable ... Thanks !

i hate minarelli engines.. try with dr evo 70cc kit + power1 vario ~100euro and upjet the carb.. u will have enough power for les money ;)

minarelli is perfect for Top Performances due + stuff....

if you want it for stunting.. use top performances giza
