Background: Apparently the Raptor Clutch lever came out of the same parts bin as the Guzzis - the stock Raptor lever is not span adjustable, apparently the Guzzi California (year unspecified) is span adjustable and will bolt up. Question: 1. Is there any difference in clutch levers between the years of the Cali that came with them, and if not, what year models came with span adjustable clutch levers. 2. What are the preferred suppliers for Guzzi parts ? JL
