Default your mileage will vary

That's a fact. I've gotten between 38 and 47 mpg. Crazy. I've never had a bike get so much variation. The MPGs seem to have dropped since the temps have gotten into the 30s.

Indeed.

All my recent bikes get much better mileage in uber hot weather. I had to look this up once because it didn't make any sense to me as the engine should perform better proportional to the density of the air it intakes. And cooler air is denser.

What I didn't take into account was how much easier the bikes glide through thin air.

The thinner is the winner.

I was getting consistent 41 - 42 mpg up until about 2 months ago.Now its like 37-38. I was wondering if they changed the ogygen mix for winter or something like that.

Could be, the best milage was from gas not sold in the Phoenix area.

How's this for crazy? I get better fuel mileage at 75 mph that I do at 65 mph. Cruising at 60, it gets better mileage if I leave it in 5th gear than if I shift to 6th. Is that strange?

I think it's the cams. It wasn't like this with the .495 Andrews/S&S cams. Maybe it needs a bit more rpm to be efficient?

I believe it. I'm not much of a drag racer, but I read once that some of those guys build their vehicles with cams so hot they can barely run at idle. They work really well WFO however.

I've noticed this too on occassion, but if I find a dead level, straight road, with no wind conditions, 6 speed gives better mpg. The the 6th gear doesn't like to pull as well as the 5th at low RPM, and at 70mph 5th NEVER does better than 6th. Duh!

I find I get better mileage when Cheryl is with me. Probably has to do with the pounding on my helmet if I ride like I do when I'm alone.
