Have just brought a athena variator for my piaggio zip 125, that came with a new clutch spring to and 14.5g rollers

My question is does 14.5 gram rollers seem heavy to you, would i be best using the standard weight rollers with this kit, all seems fine though im now maxing out at 50-60mph, where as before i could reach a steady 70mph

could really do with some help on this one, im new to all this variator stuff

Heres a pic
