Now that I have my horn fixed, I can address the other situation that's been bugging me since returning from Biketoberfest. Riding home on I-75 at a steady 75 to 80 MPH (around 2800RPM in 6th gear) my mileage was only around 35 MPG. This is a drop of at least 10 MPG from when my bike was stock. I have SE slip ons and a HD Stage I air cleaner along with my Gen 3.5 TFI. I was riding solo with no bad headwinds and pretty light load since my wife was following behind in the car. Current TFI settings, as per my phone conversation with Chris several months ago, is 3 1/2 - 3 - 3 - off - 4 - 4 1/2. Are these mileage numbers about what I should expect now on a 2008 FLHX or should I do some adjusting?
