I just returned from a 1750+ ride from the Seattle Metro Area to the San Francisco Bay Area, CA on my 08 Vision. The bike is equipped with a VFC III, Lloydz cams, Lloydz air intake and Lloydz rev extender and Arlen Ness chrome rims. It ran perfectly at a calculatedaverage (highway) speed of 71.9 mph. The longest non-stop leg of the trip was from just south of Portland, OR to Grants Pass, OR, a distance of slightlymore than 225+ miles. (Grants Pass is very close to the CA border). I was riding with two Harleys, a Street Glide and a Road Glide bothrunning 110 ci,6 gal tanks and 6 speed trans. When we arrived in GrantsPass,my friends indicated that bothHarleys "low fuel" lights had been on, for a few miles whilemy bikes "lowfuel" light had "blinked", briefly,just beforeour exit.It did notreachthe "low fuel warning" range.. I took 4.9 gallons and one of theHarleys took 5.3 and the other 5.5 gals. For the entire trip, that I personally calculated,my bikeaveraged 42.7 mpgon the highway.The bikesinstuments indicated that I averaged 44.1mpg.After filling up, the bikes instumentsstated thatIhad a highway range of278 miles. However,it would only indicate that length of distance when I "burped" the tank whilefueling (e.g.shaking the bike slighly as it fills uptoto make sure all the air escapes fromthe tank).If didn't "burp" the tank, then filled it upto the point that the gas pump stopped, the bikes indicatedrangedropped, considerably, to the range(s) of 243 to255 or so miles. From my experience ONLY, if you are on a trip where the bikes range could be important, "burp" youfuel tank to extend your range! By the way, I stopped byArlen Ness in Dublin, CAand took a picture. Onceagain,the Ness' are a family operation and boy does it show in terms of theGREAT service that they provide. Crap! I felt that I had to buy"something" to show my appreciation - which I did!One of these days I'll take the time to learn how to post pictureson this site!
