ok so here's the deal i was getting 40 to 50 miles to the gallon previously, i decided to take off my exhaust and run a stright pipe for the weekend a few months ago. Ever since then my gas mileage has dropped to 30 miles to the gallon. The guys on the FZ6 board suggested unpuggling the battery for the day and reseting the ECU. this only did something temporarily. does anyone else having anymore suggestions?
