Fuel Mileage Problem
Any ideas why my bike went from about 35 mpg to about 20 mpg? Driving speeds didn't change. Just commuting, maybe 80's on the freeway, but that was the same before and since.
Does the engine crankcase ventilation feed to the air filter? If I had too much oil in the c'case, could it have burped into the paper cartridge and partially plugged, causing drastically reduced fuel mileage.
I don't think that the ethanol-a-lene at 10 to 20 percent could have caused this drastic of a reduction, do you?
No warning lights lit. O2 sensor still in cat. Cat gets REAL hot.
What could it be????
