Your Gawdiness,

I think you may have a problem here. Most motorcycles are tuned for best eficiency at typical speed/rpm combinations. Something like 55-75 mph.

Even if you left the bike in a lower gear to gain revs and potentially get into the valve timing/intake/exhaust optimum range, you would be doing so with a much smaller throttle opening than in high gear at highway speeds.

I read a post on some site a while ago about some experimentation done in Sweden, I think, where they compared gradually accellerating up to speed vs. giving it some stick. The results showed that the faster you reached cruising speed, the less gas you used. The conclusion was that the carburetion was better at cruising speeds.

I don't know if they tested fuel injection, I imagine this would be somewhat better. Meanwhile, on the strength of this survey, get out there and peg it....er officer??

In case it helps, I will try for accurate mpg measurements on the trip to the barbeque. I am hoping to have two Motobecanes and a Batavus, all of which seem to equate "odes" to miles, not kilometers. I will begin the trip with full tanks and refill them when I get back and see what happened. Last year my best estimate was about 90 mpg for the Mb's I think. I posted the info on the site at the time but I did not have real accurate numbers. Something to do with a leaky fuel line and a guy with some gas in a non-calibrated pickle jar. : )

Your obediant subject.
