Ive been thinking of buying a pair of DP cdi units for my M900.Are they worth the price ? I already have an open exhaust with large diameter headers and Dynojet stg 2. Keihin Fcr`s are soon to be ordered. Anyone in here tried those cdi units??? If they really advance the ignition then they must be a good thing......They are called variable-advance control units in the Ducati Performance catalogue.
