The 2001-2004 Volusia were carberuretted. They used engine vacuum to actuate the "fuel pump" in the tank and have no ecu or sensors to adjust the fuel mapping. The Volusia also uses a "dual fire" spark, meaning both coils fire on every revolution of the engine (due to a lack of computer control). In 2005, the C50 was introduced with fuel injection, digitally controlled spark, MAP and MAF sensors along with other electronics which help the bike meet increasingly strict emissions regulations. The addition of an electric fuel pump inside the tank necessitated the frame be modified to accommodate the fuel pump and its electronics. This also allowed for the taller fuel injection throttle body included with the changes.
With the exception of some of the internal components, there is ZERO interchangeability between a Volusia engine and a C50 engine.
