Peugeot Speedfight 2 Ac Help!

also the tecnigas next-r is a pretty good pipe for the price and the yasuni z is pretty good too, as I had the s3r I would recommend it but got my current tecnigas next- r for £55 and it's just as good as the s3r, also polini or athena 70 kits I would say are the best (bike on the right in my pic got polini 70 kit)
