2003, purely stock.
Commuting, 34 mpg unless I'm being rowdy.
Charging around in the twisties, 32 mpg. A bit less in the winter.
Highway, I usually cruise at 70-85, 37-39 mpg.
The best is when I'm backroads touring with friends, who most often do speedlimit+10.
That gets me 39-40 mpg consistently, it's the moderate speeds and long stretches
without stoplights, I think.
'Course there's all kinds of variables. In the winter they sell MTBE gas here, that
brings it down by ?? percent. And it's 10% ethanol all the time now, that hurts too.
I get over 40 mpg if I put premium in, but I usually run regular unless A) it's really
hot weather; or I want the extra power. The manual says 87 is fine, but I think
the knock sensor is limiting max power, especially when it's hot out. So I end up
twisting the throttle further and my mileage goes down. When I'm touring,
the low fuel warning comes on at around 170 miles when I use regular, but not
until 190 or so miles with premium.
I bought my bike in August 2005 as a close-out, zero miles. I assumed that the
mileage would get better as the bike broke in, but with 17K miles so far, I haven't
seen any significant improvement yet.
