Gas Mileage

This subject came up on another thread and I didn't want to clutter it up.

Twice now, within the last 2 months, I've run out of gas at about 185 miles and 195 miles respectively. In both instances, the tank was completely full.

I'm going to figure up my mileage over the course of this next fill-up, but it seems like most people plan on 220-230 miles per tank and I'm only getting about 190 miles lately.

I'm wondering what some factors might be. I've been running a large, nearly-vertical windshield that I just took off today. I didn't remove it because of possible fuel mileage issues, but just because I think I like riding more without it, at least when it's hot.

I usually run around 270-280 and carry probably 25 pounds of assorted crap with me at all times, but that's not nearly as much weight as you guys carry when geared up for trips.

I really don't care what kind of mileage I get, but I find it odd it seems dramatically lower than all the mileage reports I read on here.

I run a stock-size front tire and my trip to work racks up the same miles as my Toyota, so my odometer's not off.

Bike runs great and I use 87-octane.

90% of the time I'm running 60 or so with a couple of short 2-mile 80-mph indicated bursts down the freeway on the way to work and back.

How much useable gas is available in the main tank minus reserve? Maybe my mileage isn't as bad as I think it is.

I have found my bike runs 4.8 gallons to reserve, and twice I have hit reserve right around 190 miles instead of my typical 240, both times I fueled up at rural gas stations way up north so I've chalked it up to poor quality gas. When I got home and filled up at my normal gas station my mileage went back up. For what it's worth I run 92 octane and normally get around 49 MPG all super slab 70MPH in 50 mile stretches.

Well, if I figure 4.8 gallons and 190 miles, that ain't that bad, around 40 or so. I knew the tank spec was 6.1 gallons but didn't know how much was lost to the reserve or simply left in the main tank when it's "empty." I've never bothered monitoring how much I put in it when I fill up.

I'm thinking two important factors are my weight and size: with all my gear probably 290+ and with the 4x jacket, I'm sure I offer more wind resistance than a smaller rider.

Never thought of the gas. Even though it runs fine, ethanol might lower the efficiency of the fuel.

That could be, I'm 6'2 and 215 pounds, with my normal gear I'm probably 250 on the bike.

One thought, check the tire pressure, I just ran out at 195 myself. Barely got 38mpg, I run a lot of higher RPMs so I know that's a factor as with traffic being light during the holiday week I was able to cruise at 80 the whole way to work. Usually I am around 44-45 even with the higher RPMs though. I checked my rear tire and it was at 23psi, pumped it up and will see when this tanks out what I get.

I filled up a couple weeks ago and hit 55mpg. Usually I'm 50 on the dot. It's been awhile since I hit reserve but I think I was switching over at 220. Once I filled up at 300 miles!

First of all no matter how big the windshield, it will always be smaller than the driver sitting behind it and I doubt we are very aerodynamic, more like sails in the wind.

That said I run my bike for 320kms (200 miles) before fill up. I do not go beyond and never touch reserve, mainly because over time dirt will be in that last bit of the tank and it builds up over a couple years. I am getting ~4.4L/100km (57 mpg) and I am 6'4" and 290lbs.

Another area of drag is panniers, but your last pictures did not have any so that would not be a problem....

How is your throttle use: (1) on/off or (2) no quick starts just riding safe...

When is the Last time you cleaned your air filter? Maybe she is not breathing good...

Changed the plug lately? poor spark will result in more fuel consumption...

i went from ,fairbanks to petersville this week and at mile 239 i had to hit reserve when i filled it up it took 4.9 gallons i weigh 220 lbs and i was 65-70 whole way ..

hopeing once it breaks in more it will get better . on the 140 mile stretch of dirt to paxson i got 51mpg ..

my worst so far was 48 mpg holding 75 mph for a while on the long flat stretches .. seems soon as i start going over 70 mph it drops quick..

I check my tires before the first ride of every day and keep my 244's at 28 psi front and rear. Could it be that those in the +50mpg range run a harder, more street-oriented tire?

Good point about the windshield. I think I'll dismiss it as a factor.

I keep the stock air filter clean but at 8,000 miles haven't changed the spark plug.

My throttle use is most likely a big factor. I don't tear away from stops and flog it all the time, but fuel economy is not on my mind when I twist it. If I leave a rural stop sign with no other traffic around, I generally accelerate pretty quickly up to cruising speed.

There are lots of reports from riders my size and weight getting mileage in the high 50's so I'm also about ready to dismiss that as a factor.

I'm beginning to think the biggest factors are the occasional heavy throttle hand and maybe also the softer tires I prefer.
