I just bought an "almost new" Vespa LXV 125 2v 4T AC with Carburettor from 2006 with 1300km on board. From the beginning it was running 60km/h. After buying and replacing from SIP the "Drive Tunning Kit Sport" - belt,sponge,clutch,spark...,main jet Naraku 96 and a visual check for other know form of limitation(intake,exaust...) it runs now 65km/h!!! - with almost the same acceleration...as without them. Very very disapointed :(
The speed and the accelation is the same with 1 or 2 passangers.
All my mechanics didn't guess where/what is the limitation...everything is new inside(~1300km) stock from factory excepting the ones mentionated.
Any hints, tips & tricks ?
Thanks in advance!
