I agree about the ROI may take a long time to happen. Took an easy ride yesterday, 55-65 MPH, and short shifted around 3.5K. This delivered 45.6 MPG, according to the bikes computer. Second half of ride, stepped up to 65-75, with higher shift points, and still got 43.5 MPG. I'm happy with the performance and mileage that the stock 08 provides. My 04 RT and Dyna give me around the same mileage. A KLR650 got me 50 MPG average, and I would rather sacrifice the few MPG's to ride the C14, any day. Hey, it's your bike and money, have fun with both... tp
