    Africa Twin RD07a XRV750 - Engine Restriction Details

    Africa Twin RD07a XRV750 - Engine Restriction Details

    There were a number of changes from year to year, so I will present the information for each year of production and provide as much detail as available to me.

    Production years 1996 - XRV750T, 1997 - XRV750V, 1998 - XRV750W, 1999 - XRV750X and 2000 - XRV750Y, RD07a 750cc.

    It would appear that 2000 model year bikes were available up to 2003.

    It would appear that the restriction modifications can be ascertained on engine number alone, but only on Austrian and German models. Bikes for the Swiss market were also restricted but their engine numbers are in sequence with the full power models, just to make things difficult.


    Also, the Honda Area (Market) Codes are my best guess. Again, if you know better then let me know.

    The situation is not as clear cut as with the earlier models, but bear with me and I'll try and make it as clear as possible.

    I will start be listing the standard part numbers -

    Camshafts, Part Nos, Front: 14110-MV1-000, Rear: 14120-MV1-000

    Inlet Rubbers, Part Nos: 16211-MY1-000

    Hi,
    Are all Swiss machines restricted (2002) and if so is it purely emmisions or power output or both and is there anything that can be done as a quick fix?
    Thanks

    Sorry, but I don't believe that there is a quick fix - not with changes to the Camshafts, CDI Units, Inlet Rubbers and Carb internals.

    I think that these changes were for both emissions and power output. As my note says the Swiss market models cannot be determined from Engine / Frame numbers alone - the individual parts need checking. One quick check is the CDI as the part number is usually printed on it somewhere.
