hi im new to this forum, i bought an yamaha aerox 50 on an 02 plate a while back,its got a power pipe on and ive been told its de restricted its being up jetted and i can only get 38mph maximum out of it? is this right or is it still restricted somewhere? cheers
sounds like it will still have a washer still in the variater or a restricter still in the after market exhaust what exhaust is on it ? as some still have restricters in ?
