ok peeps, not exactly a newbie to tuning but tbh i don't really know that much about piaggio's and the 125. i want a little more top end for my typhoon, it seems to pull well from standstill but lacks top end speed. i know the answer is going to be 172 but i want to keep it 125, any tips for a little more top end speed?? by the way, at the moment it indiates just over 65mph on the speedo, pulling 14 stone of lard but is a genuine 58mph on my sat nav.
Make sure you have 12.5g rollers in there. It should be hitting nearer to 70mph. If you dont wanna go down the 172 route then just get a 25mm carb and pipe for a small power increase... Might aswell just 172 it though.
