Todays ride was 150 miles of mostly dirt roads at an average speed of 25mph with some faster bits on pavement to 60mph.
My fuel economy was 63.3 which is MUCH improved from previous performance. I was taking it easy today. My friend on his RX3 who's about 130 pounds lighter than me with stock gearing and stock tires (I have 19" and shinko 805 plus 13T sprocket) got 70.9mpg which is excellent. Mileage is much better if you keep the bike under 6500 revs most of the day haha. |

I'm glad to hear your fuel economy is improving. Thanks for posting the update.

Until we can figure out a way to input the actual front wheel diameter in the computer, it will always yield waaaay too optimistic MPG numbers.

Pretty easy to deduct 5% from the odometer reading to obtain a close approximation of mpg. jb

Mine's closer to 10% off. That little SpeedoDRD thing is awesome, Spud! Thanks... I see in that thread, you took off 10.2% Do you suppose the .2 is for the knobbies?

I suppose the 0.2 percent is for the height of the knobbies. Every knobby tire will have a slightly different circumference, which will change with tire wear. I calibrate the SpeedoDRD with my Garmin GPS receiver. If I change tires, I can easily recalibrate the SpeedoDRD.

I just finished reversing the OCS. I don't know that the bike will run any better, but it was a pretty easy fix.

Hi Keith,
So what would account for the difference between your 10% and my 5%? I believe your RX3 and mine are both from the second shipment. Even so, it is still easy to deduct 10% from the trip odometer to figure out the miles per gallon. On the next tank of gas I will again compare the GPS mileage to the odometer. jb

We shouldn't have to be mentally deducting anything from our speedometer or odometers. I get speedometers can be slightly off because of different sized wheels, and all that. But when you are rolling on more odometer miles than are actually on the bike, I consider that a problem. It affects your resale value, and also could affect your insurance premiums, if you use the mileage limitations to gain a favorable rate.
And if I remember correctly, it's actually against the law or some federal guideline to have an inaccurate speedometer. I think the acceptable range is +/–2.5% |

I just saw this thread and found out my OCS is installed upside too...
I've been getting a pretty consistent 50 MPG with corrected mileage (about 5% over on the ODO) and a 13 tooth front sprocket... Maybe having that thing flipped will help get a little more. |
