i've been averaging about 28 mpg since new. it did jump to a whopping 29 after the new flash. but now that i have a few miles on her i'm a little more prone to heavyhand it a little and it's gone back to 28. i have seen the instant say anything from 35 to 45mpg while crusing at a steady 50mph in 4th. i'm more in it for the grins per mile than mpg. i understand that i bought a high compression high horsepower machine. couldn't be happier with the bike the way she is. if i want to get good mileage i'll take the wife's sporty for the day. she gets waaaay better mpg but not nearly as fun either... |

Getting high gas mileage for me is the amount of cruising at just the right speed.
For my 08 Escape, if I cruise at 65 i get 26 mpg, and cruising at 70 gives me 25mpg. But if i cruise at 75 it will drop to between 20-21 mpg. Sometimes those little cruising speed changes make a bigger difference then you think. |

Wind resistance increases exponentially at speeds. It takes 8 times as much power to overcome the wind alone at 100mph than at 50mph. That is why 10mph increase in speed can make a huge difference. I have gotten 75mpg as my best tank on my XB12 without hypermiling it. It can be done  |

Froggy: I just finished reading the archives. Do you name every vehicle? The only vehicle I ever named was my red 1125CR; its name is Sebastian. (Named after the crab in the Little Mermaid).
I posted this in another thread, but here is what I get:
1125CR Avg: 35-37 MPG
XB12X - 45-50 MPG
BMW 1200RT - 42-45 MPG
The 1125 has the most horsepower of any of the bikes and I think that has a lot to do with the fuel economy difference.

Yes, due to the number of vehicles I have I need to name them to tell them apart when doing anything money related. Also, when I log fuel economy, its easy to email myself "Christina - 2.12g 151.1t $3.25g 7250odo". I named the bikes, just not the car.
Yep, typically it takes more fuel to make more power. Not necessarily a rule, as many factors including transmission gearing and wind resistance come into play. The 505hp Corvette Z06 is the only 500+hp car that dosen't have a federally mandated gas guzzler tax due to its 25mpg highway rating on the newest tests. Knowing me, I could probably get an easy 34mpg out of it |

I can get 25mpg in my 500hp mustang with 4.10 gears, if I keep it under 60, but only the EPA does 55-60 on the highway.
Just filled up and averaged 32mpg this tank. I suppose if I wasn't popping the front up on ever 1-2 shift, I could get mid to upper 30's. |

I can get almost 30 mpg average in my 99 corvette. It is barely idling along at 70 with six gears....
My M2. Six gears, European gearing. Between 50-60 on the road. Between 70-80 mph. More if I drive slower. Again, it is just barely idling along at those speeds. In fact if you try to go sixty, you have to down shift to 5th gear.
Plus you are only looking at one carb on the M2 vrs. the two large injectors on the 1125 cr..... |

I get bad fuel mileage. Maybe its the way I ride? Im not too hard on the bike. I shift gears around 6k rpm. What is everyone elses shift point under normal conditions? I was showing 31 mpg with the stock flash and now I have the O S B tune set at default and only show 25mpg. I already get the (lean?) surge from having my AFVs set this low. If I add fuel, the surge goes away, but my fuel mileage drops down to about 23 mpg. This is on my '08 1125r. |

I shift at at around 3000rpm most of the time. 4000 if I just need that little extra umph. Aftermarket tunes will probably kill gas mileage as most of the time the tuner only cares about a good number on the dyno and doesn't spend the time to develop a good fuel map for the cruising range. Getting the American Sport Bike tune for my XB improved fuel economy. |

I usually shift between 6-9K taking off (on the highway) or maybe 5K in town. I usually don't get out of 3rd gear in town either. Mine has not been tuned yet, I average 39-40 mpg on the highway, average cruise speed of 70-80 mph. If I drop to 60 mph, I see 55 mpg on the instant display, but for some reason I have a very difficult time keeping it at that speed. It keeps creeping up to 70+ all the time. |

I've noticed the sweet spot for gas mileage is at 60-65 mph on the r and the Cr would be 56- 61 mph due to gear reduction. I average 37 when I ride semi aggressive. 42 plus when I baby her or as bad as 25 mpg on group rides which are pretty aggressive in southern Ohio . |

My sweet spot is drafting off a work truck or bus @ 65-75mph getting 50-55mpg shown on the instant display |

I wouldn't count on the instant display being very accurate. If the ambient temp readings on the Magneti Marelli (sp?)cluster show 55 degrees when it's really 15, how much trust would you put in the darn thing?
You can count on the low pressure area behind a truck though. |

It is 100% accurate. It calculates it based on how much fuel is being pumped into the motor. Squeeze the clutch, pop into neutral and coast with the engine off and it will turn into 2 dashes. Instant MPG is only useful for learning how to ride and keep the engine happy. Average MPG is the one that matters.
Is MM the cluster maker? Cool. AT is air intake temperature. If it says 55, the air going into your motor probably is, get this, 55! |

Yes Froggy is right. It's the way those dam radiators! The airflow from them and the fans dumps all the hot air into the intake duct. I'm guessing to help the emissions.... I wish there was a way to change it without spending a million bucks on crazy fairings and pods.... Waaaaaa !  lol
The wheelbarrow on the roof of the chevy work truck this morning really help increase the draft bubble size and its nice and warm back there too. |

I always assumed that the sensor was close to a heat source, but as I tore my CR wiring apart for the handlebar switch, I was able to see exactly where the sensor it. As Froggy said, it's near the air intake and as Cpt America points out, there is a lot of additional heat that is in that area that gets tossed in along the way. |

in the march issue of motorcyclist mag, they reported a 37mpg avg out of their 1125cr long term test bike.
which leads me to believe that they shut the bike off for downhill rides. |

If they did that, they would get 53mpg  |

If the display goes to dashes when you are coasting down the road, wouldn't that imply you are getting NO gas mileage, or, at least, that the 100% accurate function is not able to compute what is happening?? If you were on a long grade and coasted for a mile in the mountains, the cluster isn't going to make any adjustments, is it? 100% accurate is an extremely relative term. For the rest of us,as you say, it only gives a brief glimpse of the mileage we were getting a second ago and will not be getting seconds from now, created by some algorithm, right? Average mpg, indeed, is the one that matters.
And what is "cool" about MM? If my shredded memory is correct, virtually every race Fiat/ Ferrari/ Maserati in world endurance or sports car racing has broken down with problems in their MM electricals in the past. Can't you imagine the arm waving and gesticulating in the Italian's pits as the swarthy mechanics point fingers and holler at one another following one more electrical failure?
The display shows intake temperature. That makes more sense. I figured it meant ambient temperature. Guess I should read the owners manual more carefully. |

That doesn't mean it's accurate as most instant MPG are not.

Does the electronics manual illustrate the procedures for fault diagnoses well?
I have the shop manual but I guess I need the Buell electronics manual as well. Will it guide me to useful ideas about correcting my substandard fuel mileage..? |

Your fuel consumption rate is 0. You can't display what isn't happening. This does skew the average fuel economy number, so my actual tank average is always slightly higher than what the dash says. You should be calculating your fuel economy by diving the miles traveled by the amount of gas it took to refill. I just use ecomodder.com for it as you just put in the values and you get the nice charts and logs.

How would it not be accurate other than a mechanical failure or normal sensor tolerances? Thats why I said "probably is" |

The math on miles since last fill and the gallons it took to fill is the best chance for a good MPG number. You could get anal and doublecheck the mileage with a GPS to see how off your odometer is (they are typically off by 3-4% or more...not in your favor).
I usually check the GPS MPH vs the bike MPH to get an idea of the percentage it is off and apply that to the miles driven before calculating.
The problem with using the bike's instant MPG for anything other than a quick estimate is the way it calculates fuel used...it's not directly measured which will add to the error. This is why they don't average it over the tank- it wouldn't be close to reality. |
