Its actually about 64.6mph for 4k in 6th on the R. Actual speed is depending on tire tread, pressure and some other things, but thats close enough.
Here is a gear ratio calc if you want to play around with it.

I am getting 38mpg going 80 to 90mph. So I know I probably could hit some of those Froggy mpg marks on my Cr going 65mph. |

4K RPM on my R is 68 MPH.
I generally cruise at 75 MPH.
I've been doing more commuting this year and my MPG is up from averaging 29±1 to 35±1. My work commute is 35 miles each direction.
The best average MPG I *EVER* got on a tank of fuel was 48 MPG while drafting a semi through the Nevada desert heading to Death Valley in November of 2008.
I believe this was BEFORE the first ECU flash correcting the fueling issues. |

I have a quote from AMSOILs' catalog-
"AMSOIL Synthetic Motor Oil doesn't volatize (burn off) like other motor oils. The low volatility of AMSOIL Motor Oil reduces oil consumption and improves fuel efficiency."
-The black lid is a 20w-50 synthetic, is recommended for H-D, Buell, KTM, Ducati, Aprilia, BMW, and Triumph.
-The red lid is 10w-40 synthetic, is recommended for Honda, Yamaha, Kawasaki, Victory, and BMW.
Just a little FYI |

Day in and out, with the Drummer, K&N, and the ohio thing for the ECM, I am getting a consistent.......
24 MPG.
Worth every drop and penny.

Have any of you guys ever felt that little push right as you pass the front of the semi. Ride right ahead of that high pressure to let it push you and watch your instant mpg.
Or maybe he has a switch inline with one of the fuel injectors for cruising. |

That "push" is you actually getting in front of the truck and out of its wind stream. The massive flat front of the trucks push a ton of air in all directions, and if you are right by the door you will feel the brunt of it. Once you get passed, you get the little boost because there is less pressure. Similar to how flexing an arm is easier after putting down a dumbbell, as there is less weight to provide resistance. If you hide right behind the truck, you remove even more wind resistance and you can easily get 70+ mpg on the instant readout. I would love to get stuck behind one for 200+ miles to get that super tank  |

I figured that was part of it, but on the interstate I noticed about a 5mpg increase on the instant readout when I stayed just in front of the high pressure for a minute. My thought was it had an effect similar to increasing aerodynamics by increasing the pressure in the low pressure zone created by the bike and me. I guess another comparison is drafting in nascar speeds up the drafter and the drafted car. The drafted car's low pressure zone is eliminated.
I'm not a fan of tailgating, but I do notice the gain a little 100 ft back. |

Drafting a semi is how I managed 48 MPG average on a 100+ mile stretch.
And that was BEFORE the fuel remap. Would probably be much better now. |
