Up my jet?

hi, i recently bought a yasuni r exhaust from sip and installed it onto my yamaha aerox. the aerox is only derestricted and i was wondering what size people recommend i up my jet. It is quite urgent as i am experiencing loss of speed at some stages because of it.


buy a 65 jet .. that should give you a boost without having to mod the rest of your scoot
