Ciao Pajo and Aldo.
Grazie your reply.
Maybe o use he piston of 660 I need to change the cylinder too, but i'm no sure
By he way, I saw some pictures of your off road trip with Super Tenere, Dio Santo, here in Brasil it is impossiblr to do this because the price of these motorcycles are very high and the parts too.
To you know , my Super 1997 is +/- Euros 7.400.00 here, a XT 660 0Km is 9.600.00 and our salary is in Reais, not in Euro ghhghghg, 01 euro=2,70 reais.
What is cheapper here is food, services and live costs, but cars, bikes, etc are very expencive.
grazie and ciao
Rodrigo
