I am curious as to what other people are getting for fuel economy. I was running an average of 47.834 mpg prior to my 36,000 mile service when they replaced my paper BMW air filter for a K&N air filter. Now I'm running an average of 45.884 mpg.
Get rid of the K&N filter. There is a reason why the K&N allows more air flow, because it is less restrictive and allows more harmful dirt and debris to get through. Many people do not know or realize this because everyone is so greedy for better performance. Why your fuel economy went down could just be riding habits.
My trip computer shows 45.3 mpg while a vehicle log I use on my phone shows 50.45 for pretty much the same tank. However, the mileage I use for the phone app comes from the bike's odometer on my 2002 K1200LT. I'd tend to trust the computer for planning purposes.
I recently bought a stock, well serviced 2002 LT, 17.5k miles and rode it home 1,800 miles (99.99% freeway), mostly 70mph. Climbed the Sierras through Yosemite. I used premium. I calculated 50.5 mph - I was really surprised and jazzed!! I haven't calculated my around town mileage for home area driving.
I'm riding a 2006 K1200LT. Tire pressure 42f/48r, pre and post service.
I've run 2112.2 miles and used 46.951 gallons (13 fuel-ups) of fuel post service for a 44.987 mpg average. On the 2159.1 miles prior to my 36,000 mile service I used 43.627 gallons (15 fuel-ups) for a 49.490 mpg average. I'm now experiencing a 9.1% fuel economy loss.
I'm still driving the same roads, the way I always have. I may have taken a few longer rides on the pre-service, but not much.
I guess I should start with replacing the K&N air filter. If that doesn't work, it's off to the mechanic.
My 99 LT is My daily commute rider mostly on freeways. If i ride at 80-90 MPH them i get approx 37 to 40 mpg. If i ride about 60 mph i get 55mpg. I rode two up loaded with a unigo trailer from California to Utah and got 45mpg at 80 Mph.
Riding solo with lots of gear I just went over 5200 miles on our trip out west. On the Interstate at 75+ mph I'm getting 42-44 mpg on an '06 R1200RT on Michelin PR3s, using 91 octane and a K&N air filter. Two lane highways at 55-65 and I get 46-48 mpg. Without the gear on I am getting over 50 mpg. This is while traveling at elevations of 4 - 8000 feet. Now that I'm back to just above sea level in Arkansas, I expect to see lower mileage.
I have had no issues with my K&N air filter after having it on for 30,000+ miles.
On the 2000 K1200LT after resetting the TPS and computer trips, I've gone from an initial 39.7 MPG to a remarkable 62.8 MPG on my recent commute into the city of London. 180miles round trip for 9 days, 1620 miles total. It used to be around the mid 50's MPG.
It only gets better !:bike:
