everyone on here goes around the fact ,you have to slow the rpms down to  more of a  cruise range .i would get a harley rear pulley that has 65 or even 60 teeth and a belt for that application. if you are on a long ride it will help like you wont believe. the long haul usually isnt a drag race so slow the motor down and enjoy some big numbers in mpg. thats what i would do myself, take care btk572

 Haha nice tostyj... I know a couple guys that get further with that then they do with anything else.

Thanks for all the advice on the milage post. The trip went well. My first tank of gas I took it easy 65 MPH and got 46 MPG. After that average around 36-38. Made the long stretch with gas to spare. The map I used made a difference. I did some testing before I left. I ended up use the PCIII sampson stock air box map. I learned a lot with the help of a number of people. Thank you all again for the great advice.

 Keep in mind you can get a little more fuel in your tank by standing it upright, NOT leaning it on the sidestand.  It is not a lot but every ounce counts when trying to go the distance

In my '06 I have the same 10.25:1 pistons, cams, big air kit, PCIII, and V&H propipe and get 50-52 mpg @ 65mph taking it somewhat easy.  When tearing up the Catskill Mts. I get around 46mpg.  Keep in mind this is with the Shitty New York fuel as well.  Other states with BP fuel I will get even better.  I have had my bike dyno tuned with a custom map for this setup.  Stock gearing on the bike as well.
