| Captain Pubic   Joined: Aug 2012 From: Seattle I Ride: Ninja 650 or somebody elses. | What kind of change in gas mileage for fall/winter? Curious, being my first full time winter riding stint. My gas mileage has take a pretty big dip. |

I've never had a noticeable change in gas mileage. Winter, summer, fall, spring: no significant change. What have you experienced? Did you go from 45M/g to 43M/g? There's so many variables that unless you conducted a controlled experiment, you would really have no clue what caused the change in MPG. |

 I get summer air imported from Australia all winter long so I don't have to change it out.Your pressure will actually change with the drop in temps (same volume, lower temp = less pressure) so that could be effecting mpg. I've also heard of summer gas vs winter gas rumors, never really saw a huge difference in mpg though. | |

 This is good, I got's a smile even with the rain pouring down. I once rode "All" year round, although never checked the mileage.  When driving my log truck which had twenty tires on the ground I could look back at the records and tell what the weather had done on a specific day. Why, because as the road's became more saturated with water it took more fuel to push Dem tires through the resistance. On especially rainy days this could amount to ten extra gallons at the fuel pumps. Another thing was wind, which caused the Cummins to work a little harder...AJ  | |

IMO, if your worried about mileage, you missed the point of being on two wheels (or one  ). |

| Permit  Joined: Jul 2011 From: Kent. WA I Ride: 2011 Hayabusa | Assuming you are checking your tire pressures regularly as the temps change, the only other reason I can think of is the gas formulas are different in the winter. I had read the the winter formulas have a higher oxygen content and therefore a lower energy content per gallon (Btu/gal). However, I thought they didn't start with the winter formulas until Nov 1st. I check my mileage every fill-up and I have noticed a slight drop in mileage with my cars between Nov 1st and March 1st. I always attributed that to the formulas. Yes I do check my tire pressures often so that's not the reason. Gas mileage on the bike?...I check it regularly but don't worry too much about it. It is what it is and it's a lot better than the cars. |

   Joined: Feb 2008 From: Mill Creek, Wa I Ride: slower than you with a bigger grin! | Op, your recent dyno tune could have made a difference in fuel consumption due to the throttle cables going to their widest open position more often and for longer periods of time than before the magic. |
