The XFI was not sold in Canada, but the 3-tech cam company does grind here. They recommend changing the cam timing as well, which messes with the nitrogen oxide emissions but improves economy. If you have the pre-95 body, it is smaller and lighter, and can be swapped up to 13" tires to help the gearing issue. Those changes get you most of the way there. The weight difference was just cheaper trim and soundproofing. I take out most of the seats, and wear earphones for sound conditioning.
