Im about to have my valves adjusted as I don't believe the po had done it when I got the bike at 17xxx on the clock. Question is will this by any chance help out gas mileage at all? Im getting 25 mpg no matter how I ride right now. Actually less. I found out I get exactly 100 miles on my 4.5 gallon tank. Ask me how I know happened right as I pulled up to the gas pump.
