Bertb do you know my wife In my local MC club one ot our members is an old retired Air Force pilot at every petrol station he records his mileage, price of gas, amount of gas, time of day, type of gas and by the time he is finished I am one hundred miles down the road.
You would think that when Triumph decided to fit a fuel gauge they would have wanted to fit one that was accurate or why waste their and the buyers money.
Strange, I guess they have their reasons.
My R3T has similar symptoms. If I ride around town, I get 30 mpg. If I go on a long trip cruising about 70 mph, I get 40 to 41 mpg. I have the TORS, TORS tune, underseat K&N, and stock windscreen. The fuel gauge in these bikes (at least mine anyway) is wacky! When cruising at sustained speeds, the bike goes in to closed loop mode and leans out the fuel mixture, hence the better gas mileage. Not a bad feature nowadays with the price of gas being what it is.
3500 mile round trip to Arizona..hwyway between 75-80,passing at 90 plus and I averaged 40+ the whole trip..usully fueled arround 140-150 miles as I needed a break and some refreshment.Completely happy and I never use a fuel gauge..always the trip odometer!
Im surprised your surprised. Ive never seen a fuel gauge on a bike that you could trust.
The 1st thing I do with any new car or bike is fill her up and note the odo reading and work out how much its costing me.
I like the way the gauge works.
On mine as it hits empty the fuel light comes on(not exactly the same time) and I know I have approx enough for 100 klms or a 1/3 of a tank which is just right in rural oz with the longer gap between fuel stops.
I have got 336 klms (210M)from a tank from full to empty.
