well ive just fitted a yasuni r on my aerox 70 it had a giannelli pipe on before all fitted by tdr scooters the owner who i bought it of said it had 3.5g in, so i fitted the yasuni sounds great and when i riden it somewhere you can feel it kick in but then from onwards say from 20 or 30 it's just slugish from there so ive been told lighter rollers, i'll probably take it down to tdr to get them to sort it all out how it was before but with a better pipe Thanks.
if youve got the cash then i would say take it to TDR scooters, they know their stuff, and post on this forum too for my 2pence worth of advice, you didnt say which model of giannelli pipe you originally had fitted, but the yasuni R is a pretty revvy and powerful pipe compared to most giannelli pipes, so yes lighter rollers as well as tighter clutch springs and maybe a small increase in the main jet and a tweek of the mixture screw maybe needed Aerox's use silly light rollers compared to a lot of other makes like piaggio or peugeot :yahoo:
yeah think il take it to tdr since i aint that bad on cash atm :grin: and it was a giannelli extra i think, and i dont have a clue why most aerox's rollers are light compared to others :blink:
