I'm getting horrible gas mileage (20-25mpg) on my eikon 150
I can only go 45-50 miles before hitting reserve. When I fill up i only have to fill it up 2 gallons. The capacity is 4.5 gallons. I should be hitting reserve w/ about .8 gallons left.
i don't know if the two problems are related though.
I have a slighly dirty air filter that had been soaked in oil but i was able to rinse it out. I have a new filter on the way. Can this cause the problem?
What else should i check?

its not the gas its the price of the gas that seems like bad mileage go to gas station and fill till gas pump clicks off at slow fill record mileage and gallons to fill/road test for 25 miles go back to same gas station same side of gas pump and refill at slow fill and record miles and gallons to refill this will give you best practice for fuel mileages/PS drive in cityor highway not both causes difference in gas mileage
My friend, the reserve is to get you to the gas station not the next town. Only a foolish person depends on the reserve for transportation. Do not count on the reserve ... fill up every 100 miles and you will never run out of gas. Forget the reserve setting. The ONLY reason for a reserve position is to account for the lack of a fuel gage. Stop pushing your luck. There is nothing wrong with your bike.
One tank of gas is not enough to compare mileage. Or are you saying the computer's readout of mpg estimate is showing less? Try a tank or two of premium and see if that helps. Keep track of gas mileage. Driving techniques have a lot to do with gas mileage, as does long trips vs. short trips, highway cruising vs. city driving. For best mileage, do regular maintenance and keep the car in top running condition-good spark plugs and clean filters and clean oil ! Attend to minor problems before they escalate. If you want to check actual miles per gallon, start with a full tank. Write the odometer reading down, and go. Everytime you put gas in, write down the amount. When you are close to 1,000 miles from the time you started, go fill the tank and include that amount of gas to your previous list. Now add up all the gas used and divide it into the miles to get miles per gallon. (976 miles/31.8 gallons = 30.69 mpg ) . Only one tank will skew your numbers, might be off cause the tank was filled more to the top than the previous fill-up. About a thousand miles of driving will give you a very accurate figure of miles per gallon for your car.
There is no gas gauge. You have to set your trip mileage on the speedometer to 0 each time you fill up the gas hog. I go 80 miles before I have to switch the tank to reserve leaving maybe 20 miles left before walking. Don't even think about pushing that bike to the gas station just leave it. You will need a good insurance policy to protect against theft if you leave it unattended.
Look for a hole or leak in your air intake tube first, then do a basic tune up...plugs/rotor/air filter/dizzy cap (if needed) and inspect vacuum lines for cracks......these would be the most common causes of your problem
Check your plugs!! If they are dark grey or black you are running rich. Then I would verify that the mileage really is 20mpg. Run gas out until you hit reserve, then add 1 gallon and have a friend ride beside you (with an accurate speedometer) until you hit reserve again, then check your mileage against his. If you have an electronic speedo with digital odometer, they have been known to go haywire for no reason. H-D recalled a bunch of electronic speedos about 2004. Yours could have croaked. A slipping clutch or massive intake manifold air leak will wreak havoc with mileage too. Other possibilities are a weak/failing coil or ignition system, leaking needle and seat or stuck float, low compression (head gasket or bad valve).Do a compression or leakdown test. Make sure your choke is not turned on or stuck part way closed. I have also seen a bad alternator and/or battery decrease mileage. Your brakes releasing properly? No bind in trans or drivetrain? You change tire size or sprockets? Hope this helps.
