I have an 06 with a PC2 and everything else is stock. I only get 126 miles to the tank before the light comes on with 4.2 gallons of gas. This doesn't seem right. Everybody else seems to be getting better milage so what am I doing wrong? I don't drive it crazy or anything and I have a cobra exhaust and a set of K&N air filters. If I make those changes will things get worse? I'm open to suggestions and I don't ride to save gas but wow this doesn't seem right.
