    They are not the only people to have done this as Alpha Romeo did it with their T-Spark engines.

    According to them, it caused the furl in the head to burn faster and more efficiently as it was being ignited at two places simultaneously.

    The Royal Enfield Thunderbird also used this in its 350.

    For a 2-stroke like the MT, this would probably go a long way to making the acceleration a little more immediate - not that it really needed it!
