Gas Mileage

[Scorpio65]

Whats a good average for gas mileage? I think i should be getting better than i am. I drive mostly highways back and forth from work, 100 miles round trip. I average 80 to 85 mph. I have a 2001 GS500 29,000 miles and a V&H exhaust. I'm getting around 38 to 40 mpg. Is this normal? :dunno:

I rejetted mine with 137.5/62.5/20 and I get 43mpg now. I'm going back to stock because I used to get 55mpg easy.

[Phaedrus]

That's not too bad, I don't think. 45mpg seems to be pretty average, but you are into that throttle pretty good if you are really going that fast (indicated or adjusted?). Either way, slow it down a little bit and you should see better mileage. How are your plugs and air filter? Clean and replace them if there is any doubt  :mrgreen:

[Alphamazing]

45mpg is AVERAGE? I see people on here getting mid 60s... Hell, my dad's FZ1 got better gas mileage than I did on our ride.

[tdan553527]

Yea, my 04 started on average about 63MPG, after rejetting, getting about 53-55 on average.

I think it is average if you ride it like you stole it and don't have everything in tip top shape.   Do a search, it isn't uncommon. Riding style has a lot to do with it. If you are easy on it and it is properly tuned, I'd say a lot higher...but at 85mph, wind drag, a less than perfect air filter, less than new plugs, and a happy throttle wrist..... :mrgreen:

I filled up yesterday - here's the info:
14.4 litres / 305km
in Canadian terms: 4.8 litres /100kms (my CRV gets 10L/100kms)
converted => 59.9 miles/UK Gallon (Canada too)
or => 49.9 miles/ US Gallon

That's about the numbers for all my riding. I do try to stay out of the City though for the most part.

I get 45-50 mpg, driving 70 miles a day. About 45 miles of that I'm doing around 80mph or above.

I have stock jetting, a Givi A750 windscreen, and a 15T front sprocket.  Thinking of going back to a 16T and maybe even a 17T.

Never gotten anywhere near 60mpg.

[Roadstergal]

Never gotten under 60mpg on a GS.

[RVertigo]

I'm 170 and have a 15T front sprocket...

Ride it like I stole it with 50% freeway == 50+ MPG.
Ride it like I stole it with LOTS of warm ups, short trips, and less than 40% freeway == 40+ MPG.

And that's with a 15T.

I would say 40 MPG is pretty damn low...  But, the pipe and rejet might have something to do with that.

[RVertigo]

Never gotten under 60mpg on a GS.

Yeah, but you weigh like 8 lbs. :dunno:

I'm 6-foot-5 and 205-210, so I have an aero and weight disadvantage to Roadstergal. My average around town is 45-50. The best I ever got was 59.6 on about 170 highway and 25 city miles. My bike is stock -- no rejets, aftermarket exhaust, etc.

My F250 gets 11 in town and 16 on the highway, so 45 on the GSF sounds great to me even if others get 60.

[rtcpenguin]

Usually get ~180 miles of of ~3.5 gallons, so roughly 51 mpg.

I weigh a around 190lbs.

[edit]I spend 70% of the time in city traffic

[Alphamazing]

I always ride like I stole it. I also calculate my fuel consumption on my weekend rides where I can "safely" ride it like I stole it without having to worry about traffic. I'm 135ish and when I had it stock I could ring the hell out of it and get 55 or so, and now it's to 45 with the rejet. It's just too rich, despite the fact I followed the suggestions on the site here. Jetting should not destroy your gas mileage by that much.

[Roadstergal]

Ja, my mileage went from 65ish to 63ish when I rejetted + pipe.  Not really statistically significant.  I think a lot of the guides have you go up more than you need to - the dyno on mine looked like a fairly nice curve.

I know it's probably kind of too general, but what kind of tuneup can help? I am getting ~37mpg

I have new air filter, new plugs and cleaned the carbs about 3 months ago. plan to adjust the valves, but not there yet. What else?

[Alphamazing]

On the off chance, RG, do you remember your jetting numbers?

[porsche4786]

On my very first tank I got 45mpg, now I've been getting about 55mpg, I don't ride it too hard since I'm still under the 1000 miles (900 something). It was wet this morning, but other than that it looks pretty good out there, damn work...

[ditchdoc1017]

I get 55 to 60 after rejet.

Carb synch maybe.  Check your tire pressures and chain also.
