I live in a rural nevada town at 7000 feet elevation, I purchased a v star silverado 1100, approximatley two months ago, I havfe approximate 3000 miles on the odometer so far, but I am only getting around 35 to 40 mile per gallon. I was wondering what I can do to increase thie milage.I plan on re jetting it next week. Would replacing the orginal exhaust or at least removing some of the inter core help. I would like it to sound a bit stronger also. If you have any ideas please advise.
