New to these XS650's and this forum. Just curious what you guys are getting for fuel milage on a stock bike(or modified). My stock '75 is only getting 41-42 mpg. Runs great though, 11k miles, no apparent major issues, tires properly inflated, filters clean. Every so often the bike spits back through the carb. I live at 2500'asl and ride to 3500-4000 asl daily. I am running 87 octane 10% ethanol over a NGK BR8ES plug that stays pretty dark, problem there? I can get non-ethanol fuel but it's 25 miles away. Any thoughts? Thanks, JOE
