fuel consumption

Postby 2wheels » Mon Mar 16, 2015 1:52 am



My 1989 GL1500 idle and runs fine, firing fine on all cylinders, but for some reason it's burning way too much fuel, can someone give me pointers on fixing this problem?

It burned 3.1 gallons on 89 miles which seems unreal my gl1100 does way better than that.

Had the same problem this weekend. Got call my first grandbaby was coming was on the way. Nice weather and no hesitation to twist the throttle to 90 mph. Filled tank last night and only got 34 mpg, never this low ever. Did have a 50 pound glider rocking chair strapped on back. Went 141 miles on 4.1 gallons of fuel but bike has been run in garage over winter. I always fill tank before going home.

Got black soot in the exhaust? I had that problem once :cry: . Sure was an easy fix when I finally figured out that the choke was still part way on. :shock: I'm not much on the 1100s, but you should be seeing signs of it running rich if your mileage is that low.

May I suggest checking mileage again, and this time considering speeds, load, direction of wind in relation to direction of travel, driving habits, temp difference between fill and refill times...etc?
It it surprising to me how much mpg fluxuates on my 1100 do to driving conditions-particularly lower speed low gear driving. I guess a new grandbaby could do it to....slow down papa... :o ...there may not be a problem.

I'm not complaining since I traveled 65 miles running hard on interstate with an extra load. Todays ride was back to 44.6 mpg.

Just to give you a idea, I have a 96 Aspencade, Tulsa +4 windscreen, and about two weeks ago I went to Wichita Ks from Oklahoma City where I live. about a 10 mph head wind going up, none one the way home. Ran at 75-80 mph and got a average of 35mph over all.

Did gas mileage just suddenly go bad? From what others post I see gl1000, gl1100 and gl1200 all get better mpgs than gl1500. Best fuel economy I seeing is when speed is 45-55mph.

Oh No ! She had been there a few days already. She don't like riding any faster than 65 mph.

Would not agree to that statement. Two riders with 1200's in our group don't get as good as the 1800's, especially when trying to keep up at 70-80 mph. A lot depends on how one controls his wrist and stop and go traffic. You can ride a mile down the road with the same fuel needed for a rapid launch from a stop sign.

Ranged between 45 & 75, probably averaged around 62 or so.

I think I've fixed my fuel problem as well, before the work, I was averaging about 28.6 miles per gallon regardless if it was hwy, or city as long as the bike was running that was the best, but yesterday I took it out and filled it up, road it around the valley @ 65mph for about 43.7 miles went back to the station and refilled the tank it held .92 gallons. I actually couldn't get the whole gallon in, fuel was about to run out on to the ground, so I'm very pleased at that :lol:

That's 47.5 mpg on open road and if you do the same test in town it may be under 30 again. Stop and Go will kill your mileage. I'm not afraid to ride hard but choose to use a light wrist. My ride group is half retired Law Enforcement so speed is always there, just not from a stop and it shows in our great fuel mileage. Don't live in a heavily congested area and that helps a lot.
