Hey! Just wondering if you guys can give me some quick pointers. I've just bought myself a new Yamaha Aerox 50 scooter, I'm eager to tune it but to be honest with you I'm struggling a lot on knowledge. The only thing that I know is that I'm going to be buying a Leo Vinci TT exhaust and a Pollini variator. The first thing I'd like to is since the aerox is restricted in the exhaust and variator ( something the retailer told me), when I fit the components I mentioned, will this save me having to pay for the garage to derestrict it? Next thing is: what are rollers, where are they found and how easy is it to change them? and lastly, what else would you suggest doing to it so that it really hits it's potential? cheers guys and sorry about the long post!
