Have had my '24 RTR for a year and a half. Had an average MPG between 16 & 17 MPG consistently. Now I notice that my MPG has gone up to 20 MPG after the last 2 system updates. I haven't changed my driving habits and always purchase fuel from the same station. Do these updates affect engine tuning or am I just getting lucky? With MPG, not the other thing!!
 Thank You.
