Lot's of threads on the VROD's fuel consumption. Now there is another one. I recently installed the UE 5 gal tank. Had a few weeks of riding to learn the mileage limits and how the gauge reads. One thing is for sure. The VROD gets really thirsty when running 5k or more for any length of time. I have gotten as good as 39 mpg on a conservative ride rarely going over 70 mph.(As rare as an honest politician.) Got 200 miles on that tank. Others have gotten more and less. YMMV. The other day I ran a through a tank on the Turnpike. Speed limit was 80 and I rarely got under it. Many times got over it. But mostly running around 85 to 90. After the last toll booth I was cruising along about 3 miles from the house when I felt the dreaded bog. I ran out of gas at exactly 140 miles. I didn't expect that. That tank ran through at 27 mpg. That is one hell of a range difference! And I have the 30t front pulley. Now I know.
