08 RKC gauge is way off too...

 

Maybe they don't want people seeing how hot these air cooled/catalytic stifled engines really run.

 

Good point Bill

 

SO, it's agreed that the gauge sucks. Thank you all for your response.

 

Think of it as a "guide" rather than a gauge... understand your mileage and use the trip meter...

 

Yep, my gauge on the 2008 is not too accurate either - it points to "E" and the range meter still has 70 miles on it... I run the range meter down to "LO" before seeking gas, and it hasn't failed me yet.

 

On the 09 Heritage Rental gauge said I had 26 miles to go then proceeded to fill it up and took 3.2 Gallons in a 5 Gallon tank ..

 

+1 on the miles to empty feature on your trip computer. Your 2010 should have it. Seems to be pretty spot on.

 

Has anyone ever tried to "report" this under a warranty claim? My 2010 SG says its empty with over 2 gallons left in a 6 gallon tank......just wondering. Its a shame they put such a crappy guage on a bike that costs me over $25K. So much for "American made quality".

 

Have 03 Ultra, Always top off every 100 miles. Just a habit I have dont trust gauge at all and never did. I have went as far as 150 miles before fill up. But I have never went past that.88Cu,screamin eagle air,reinhart true duals and dynojet power commander.
Also have 03 Fatboy and gauge works perfect and has from day 1.
