GZ250 Gas Mileage

And yes, running it a lot wide open will cause the mileage to go down.

Hey there..

It was topped off on a 3-gallon tank, and I ran it to empty. I actually coasted into a gas station. I was thinking the 85 mpg is achieved through easy riding (heh). Oh well, 60'ish mpg is better than the 28 mpg I'm getting on my car.

i got 68mpg on my first fill... ... i run it pretty hard also.. so i think if i tone it down a little i can get a more

You get lots better mileage than I do at any speed. So does my wife.

At Franklin I'd be surprised if our average speed was much over 45.

That is some interesting data. It seems that you were getting some pretty good mileage until the windshield install and needle shim mod. Those changes were done fairly close to each other, but it would seem that the addition of a windshield had a significant effect on MPG.

Did you have any windshield at all prior to the Suzuki windshield mod?

During your trips were you carrying extra weight? Mileage really nosedived during those times.

Just trying to get a sense of what configuration will maximize fuel efficiency.

yep, you were at Franklin and witnessed the gas mileage difference. Even Gazooks Mike got less mileage than I. Love the little bike, but cant ride both at the same time, so I am probably going to sell the little guy sometime in the near future (before the Florida move). I did lose a few mpg after I installed the 16 T front sprocket. I hated that thing, I switched back to the 15 T, rode to work on the Interstate, got back the 13mph top end I had lost with the 16T and I got 72mpg doing 70-75mph on the Interstate for 100 miles :-).

While it might not seem logical, there is often less wind drag with a windshield because the shield is more aerodynamic than the wind hitting your chest etc.

In my book, a windshield is required.
I don't like bugs, rocks, birds or even rain drops smacking into me at 50 mph!!!

I just put on a new, large shield. My riding is so sporadic and varied that I won't likely know what my mileage is until late July after my trip to Atlanta.

Good gas mileage is nice to have but once on the bike its shot to h--L with the side trips or just cruising ... as in i went to the pharmacy today 1.5. miles ... it took two hours ... but i had a very nice ride .. so there goes the economy ...

[turbo chicken]

after my fill yesterday... i clocked in at 62.something MPG...

I'm going to tone it down a little on the freeway and keep at 60 or under... (speed limit is 60 anyways) i'll be crusing in the slow lane all week and see how that turns out...
