I just recently bought a 97 850 GLT with 120,000 miles. Well, I have been monitoring the gas mileage pretty closely these last few months and I have only been getting between 16-20 miles per gallon. I know that this is not what the car should be getting. Does anyone have any idea why I may be getting such horrible gas mileage??? I must find the answer to this problem or its time to get a new bike....any advice is greatly appreciated. Thanks.
