Terrible mileage on my 214 RTS

[joebryanjr]

I have been disappointed that I have not broken the 40MPG mark. I average about 38+. 2014 RTS SE6. Around town and out on country roads.

Perhaps you are riding the 2014 like a 2012 with higher revs in lower gears. Just a guess.

My last tank was 36.47 (36 mpg). Normal, 40-41. I am attributing the lower mileage to the colder temperatures outside. My car always gets less mpg in the winter. Another possibility, winter grade gas?

My driving techniques and my fill-up procedure has not changed.

Yup! The cooler, denser air that's going in the bike, requires a denser charge of fuel. (More of it! ).

True, but colder, denser air combined with the added fuel is more efficient. The net result should be giving you BETTER fuel mileage. Otherwise, everyone would be ducting the intake air off the exhaust manifold. This is why car manufacturers go to so much trouble to duct ambient air to the intake.

It does produce more power... but I've yet to see a vehicle that didn't get a little bit better fuel mileage, once the temperatures climbed.
Perhaps it's because we're cold; we're in a hurry to get the trip over with, and are stoking the fires more vigorously?
