i have a 98 bandit s 600 that was left by my wife´s ex husband. it´s been sitting up for about 8 years and we want to give it to my son for a ride back and forth to school. because it´s been sitting up, we need to drain the gas and oil, replace battery, and give it a full look over. i know nothing about bikes, so can anyone tell me how to get some of these things done without taking it to a shop? thanks for any advice you can give.
