I just got a 2011 ninja 250r to ride but the gas millage is not the best. Im getting 40 miles to the gallon. I have to ride 15 miles at 70mph and im wanting to get better gas millage. I re geared the front sprocket to a 15 tooth but what else can I do??
im 6'2" 205 but the rpm run kinda high. I have done maintence on it so Idk where to go. I though about putting a 42 tooth back sprocket and new twin brothers exust system and new air filters.
