Full disclosure... I am in Los Angeles, CA. It doesn't get really cold here. "Cold" here means 40-50F...and yes, I still rode in those temperature. The past few gas fill up were between 70-80F. Not sure if temperature range has that much impact on MPG, as speed. And I am using US gallon, not imperial.
Also full disclosure... I use 16T front sprocket and factory 47T rear, so yes I have a taller gear ratio compared to a standard Wee. My RPMs at 85 indicated is just a hair shy of 6000, I would wager they're around 5800-5900.
Here is my log, this is how I track MPG and costs...
I crashed the bike soon on April 21, and laid off riding until my knee healed. You can see the trend in MPG soon after, as that's when I started keeping it at 80 or under.
Replaced the broken bits, back on the saddle and only changed my speed. And here in LA, if you don't at the very least deign to keep up with traffic, you get run over. I've seen fully loaded 18 wheelers haul ass @ 75 MPH, and pick up trucks with heavy trailers (think Dodge Ram with one of those 4 car carrier trailer
) in the fast lane passing everyone. As much as I would love to be in 2 lane freeway puttering away at 55, I really can't do that here on the freeway.
I thought maybe its something like winter blend, but here it doesn't even get that cold enough to justify winter blend.
And really, I'm getting good mileage? I would've thought most of you guys would be getting what I am getting... I've noticed that no matter what I do, if I lane split in heavy traffic @ 40 or cruise at 80, I get approximately same mileage overall. My commute is 60/40 freeway/city, though some days I end up doing 90/10 due to my clients.
