Hi everyone. New member here. Just bought a 2016 Kawasaki ninja 650 with salvage title and 1500 miles. I need help. When I ride it the odometer is not reading the miles right. For instance I can ride somewhere that’s just 5 miles away and the odometer was I’ll add 50 miles or 40. I probably should only be at 1800 miles right now but the bike is now at 2500 miles. Any help ????
