can you give me the URL adress of your page?? I had some problems with an ignition coil (very expencive stuff!), and with the main O-Ring on tne cylinder, and these are all problems that i´ve ever had witn that bike. Giannelli Silencers are produced in Italy, and they can also be bought here, in Slovenia, but they are worldwide known, so they can be bought all over the Europe. they are quite expencive, for Aprilia RS 125 ´00 it costed 250 € (my friend bought it last year).
