Cam swap update: The Postman and I took our K9's for about a 250 mile ride today with the new .585 cams. The cam makes the engine have a little more of a "Po-ta-to" sound while at idle. Riding 2-up with my wife I got 45 miles per gallon on the first 100+ miles, and then got 41 miles per gallon on the second 100+ miles. There feels like a noticeable increase in low end torque which was exactly what I was looking for in the cam swap. I enjoy cruising down the road in the 55 to 65 mph zone, and I rarely wind the engine past 3500rpm before shifting. No increase in valve train noise, and overall I am very happy with the cam choice. We were riding the hills of Tn. in the Rock Island area, some areas are very steep and sharp curves. Performance is exactly what we hoped for.
