    Product description

    Version A for Triumph Twins 790cc/865cc with carburetors (2001-2008):
    - Bonneville
    - Thruxton 900
    - Scrambler 900
    - America
    - Speedmaster 900

    Version B for Triumph Twins 865cc with EFI injection (2009-2016):
    - Bonneville
    - Thruxton 900
    - Scrambler 900
    - America
    - Speedmaster 900
    The EFI version includes an electronic eliminator which allows you to remove the air pump without getting the engine-fault warning light.

    Benefits of removing the AIS system :
    - Simplified engine environment
    - Reduced exhaust gas temperature, thereby limiting the appearance of blue "flaming" on exhausts
    - More progressive deceleration, without backfiring 
    - Small weight gain approx 1kg

    Also essential if you want to fit individual air filters instead of the big "air box".

    Note: This change makes your non-compliant with the original motorcycle, and as such it is no longer strictly legal for road use. The installation of this kit is your responsibility.

    The AIS kit works really well! After installing no engine lights whatsoever. Also, a noticeable difference in acceleration with the throttle, deeper/better sound with the stock exhaust, and as far as I can tell the engine has yet to shut off at light or following a stop.
