I've got a 2005 M50 with just over 10,000 miles on it. I picked it up in March as my first bike and have a question as to how horrible my gas mileage is.

I'm 6'2" 240lbs and my first flashing light comes on about 110 miles into a tank. I usually don't let the tank run past 125 or 130 before filling up since it turns solid right around there. That seems like it puts me a little low as far as mileage!

Most of the commute is in town (2.7 miles). The bike is stock other than the SpitFire windshield and I debaffled the pipes a couple weeks after I got it.

Is there something that I should be looking at first?

Thanks!

I get 36 -42 mpg. Half freeway half city miles. I think it is just the way I ride. I tried to "cruise" on one tank to try and get better mileage, but it wasn't any fun. So now I just don't worry about. Motorcycle Cruiser list the mileage as :Fuel mileage: 38 to 49 mpg, 42.9 mpg average...

What are you calculating as your average?

i've gotten from 32 to high 50s...

it really depends how i ride...
fill up your tank, go cruising, with slow accel and decel and don't go over 60mph..

then fill up again and figure out how much fuel you used for your distance... :)

I would say just over 34 m.p.g. on average. Going to recheck that on this next tank. 3.8 gallons on the fill-up after 130 miles.

This is usually in town driving.

I get at least 130 in town.

Maybe you spend more time at red lights, stops signs, or idling to warm up? At those time you get 0 MPG.

I Check min on every fill up and I get 50 +, even 2 up riding.
The worse I thing I have gotten was 48.
And I have added the FI2000 to fix the lean surge, but I have the pots adjusted
to add just enough fuel to stop the surge

For me I can consistently add 3.3 gallons if I pull over and fuel up just when the low fuel light comes on. So I base my mileage calculations on that. Thursday I did 120 miles on 3.3 gallons which comes out to 36 gallons. 80% of this was interstate riding at 80-85mph (speedo read), lots of hard acceleration. I can get 45mpg if I drive like a grandma.

I usually fill tank up with bike leaning on kickstand and get around 45mpg but this last time I held the bike level and filled to bottom of filler neck which resulted in 52mpg on this tank.

Mix of city , rural and Interstate driving, mostly rural.

Dang, I though you fiddy guys got better mileage than that. I consistently get 40 in the city with my 90. Superslab at 75mph I average 44mpg and have gotta as high as 48.5 out on country roads. I do have a Bully stage 3 so I suppose that make a big diff. over stock.

I normally put in 3.6-7 gallons of fuel. I do drive like a grandma and get around 150 miles or a bit better out of it. I rarely drive over 65 with it. Not to save fuel...but to enjoy the ride.

BTW...how are your plugs? Air Filter?

Holding the bike level while filling up improves fuel economy--Brilliant!

Hey, DJ--I've been around, just not posting much lately. But I'm getting ready to start a couple of mods over the next month, so expect to see more posts from me, either about the trouble I run into or the results (or both)!

I know the bike was serviced right before I got it, and I have another 1,000 miles to go before I get it serviced again. I don't have any experience on motorcycle maintenance, but finally got a copy of the manual and am going to look into pulling some parts off and checking everything out.

I'll check the plugs and filter today.

Oh, and as far as how I fill up. I keep it on the stand and fill it up to the very brim thinking that as it stands up, it will drop the level. Also, the first time it hits the brim I shake the bike a couple of times to level it out and get any bubbles out of the way. Usually drops the level a little and allows me to put more in. Am I the only one that has to hold the sleeve on the filler up to get the gas to pump? Probably not...

Nah, having to hold back the sleeve is normal. Its some safety feature, maybe for vapor lock? It forces you to push in tightly when you fill up a car, but with a bike you have to use your hand. As for me I only average 36-40 miles per gallon. But most of my riding is stop and go town driving as well a a ton of hills. In New England if your not constantly going up and down hills its because your still parked. Those two factors together cause me to get lower mileage out of the tank than some of the other people here who live on flatter land.

Yeah, I was thinking the same thing. I wonder how many miles we could get if the bike was pointed downhill while we filled it up? We would be coasting most of the way then!

I ride a good mix of highway and country roads with a little city driving thrown in. I clculate mileage every tank, and do an avg every 10 tanks to get a more accurate reading. Prior to putting the windshield on i averages mid to high 40's, since putting it on, the worst tank I've had was 50.5mpg. For the most part, I average right at 52mpg consistently. I ride easy on the highways (NC ranks in the top 5 for speeding tickets handed out per year, and in the top 3 if you calculate it per driver, I'm taking no chances on the highways around here) but I ride pretty hard on the country roads.
