So it warmed up enough in NY today for me to take a 200 mile cruise to nowhere. Anyway, I use the trip to try out some new accessories -highway bar with pegs,
throttle rocker, to name two. Riding with my feet up in the air was outstanding!! Being able to change positions sure makes a difference. What I found that
even with the fullest of tanks, I had to switch to reserve at 110 miles and gased up at 125 miles (didn't dare to go any further and I was out in the
middle of nowhere - no telling where the next gas stop would be). It figured to about 33 mpg. I was doing better than 40 mpg last year, however it turns out
the T was running lean (some backfiring on deceleration). Since the fall, I had the carb jets checked/adjusted ( I have a Vance and Hines exhaust - it appears
the previous owner never retuned the carbs so I did), new plugs. Any thoughts on my gas milage or ways to possible improve it. I know the T isn't know for
its touring range, but is 110 -120 normal?

After changing exhaust getting the fuel-air mixture correct can be tricky. There can be lower fuel economy. Especially if the engine has substantial popping
during decels the mixture is off. Before trying to adjust make sure no air is leaking on both the intake and exhaust sides (tighten the rubber intake boots
and make sure the exhaust seals are tight and in-place), then see if you can adjust the carburetor fuel mixture screw before again trying to re-jet.
Don't forget that you lose about 2 mpg in cold air. That happens in cars too, just because colder air is denser than warmer air and it takes more energy to plow through colder air. Was this 200 mile cruise through city streets, on rural highways or on the Interstate at high speeds?

Another thing to consider is that putting those feet in that comfortable "feet out" position increases the frontal area of your motorcycle quite a
bit. Not just the feet, but legs probably farther out etc. May not make a huge difference, but with the reformulated gas that is what we have in most cold
states, plus the colder air, plus the new jets, that is probably why you got such low MPG. These bikes, from what I have seen with my wife's bike, should
get about 40-45 most of the time.

if the gas was sitting all winter in the tank with sta-bil or seafoam, I always notice that tank gets worse gase mileage then the second tank full does.
Keep your knees in the breeze!

Thanks for all the input/ideas. The jets/carb were adjusted by my local, reputable professional bike shop (I wouldn't dare mess with it...). He's
always treated me right and I trust him. I am on my second tank of gas this year and yes, it was all highway driving (more or less around the speed limit -
unless you can prove otherwise
 ) The backfiring was corrected with the carberator work. I can understand pushing more air with my feet out. I'll have to
think about maintaining that position although it was great and I felt no discomfort after the ride. I will check the intake boots etc for leakage. Lets just
say that it sounds like the more I ride, the better it will get.
