    6.8 IGNITION AND ELECTRONICS — FOUR-STROKE
    6.8.1 Replacement batteries are allowed but must fit into the original equipment battery box and be securely fastened.
    6.8.2 The original electronic control unit may be modified or aftermarket so long as it does not offer any additional inputs or
    outputs than the original unit, and it must connect with the original connections. No additional sensors may be added (e.g.,
    exhaust gas temperature, detonation sensors, etc.). Engine temperature sensors may be disabled.
    6.8.3 Ignition timing may be altered by slotting ignition trigger mounting plate. An adapter plate may be used for the sole
    purpose of relocating the ignition trigger.
    6.8.4 Aftermarket spark plugs with a different heat rating may be used.
