So I got my bike running after it sat and rotted for 2 years. The bike is only firing on one cylinder though. The right hand cylinder is the culprit. Getting spark and fuel. Time to see a mechanic?\n\n\n\nhttp:\/\/www.youtube.com\/watch?v=MHkwGqBpXqk\n\n\n\n\n\nHow are you sure it is getting spark and fuel? Did you teardown the carbs and completely rebuild and clean them?
