Fuel mileage

tsp45acp · 09-28-2008, 12:31 AM

Completely stock 08 Sporty 1200C.

Worst was 36 mpg, but it was throwing a check engine code (some wire in my ecm had popped out--the green one w/white stripe)---just got the 1000 mile service done today.

Previous w/o the check engine light was 43-46 mpg. Mostly around town 4th gear driving and often weekend errands with the wife on back.

Impatiently waiting to get a real weekend run (poker or other event) to see what it really gets out on the road.

Added a windshield last weekend so I'm wondering what additional diff that's going to make. Tracy

I have a '04 Ultra and usually set my cruise at 74 mph according to the GPS. Stage I A/C and SE slash cut pipes.

Solo I get around 42 MPG(39-45 depending on the wind)
2up Drop by about 2-3 MPG

If is go any faster they drop in a hurry!

1999 FLHTCUI I got between 40 and 50 when it was new...
BUT
now only 25 to 40 ...

of course the 25mpg comes when I am on the highway doin a steady 80mph

it has EFI but it also has over 100k on it

Do older EFI equipped bikes get that poor fuel mileage? I just got back from doing an 800 mile loop to Northern California...did 75+ and got 54 MPG...(first time I got to really take my 2004 XL1200RS carbureted model with all freeway miles, (typically get 48MPG mainly city).

Have you checked & changed your plugs and did some "Throttle Chops/Plug Inspections" per Glider' piece on the subject to see how your plugs/mixture is doing? You also may have dragging brakes or really get on it like a jackrabbit to get it down that low?

MPG is relative to speed, the faster you ride, the MPG goes down. Ideally the best MPG should be at about 55-60 MPH except for the 6 speeds.

So does that mean his Harley is okay with a low 25 and high 40? Just seems awful low...just curious!

25 is a bit low but the 40 is a respectable number.
