I have a 05 with 17,000 mile on her. What preventave maintance should I really be doing to the bike or should I be following the owners manual schedule to a tee. I have had no problems with the bike, except for the hot starts. I have replaced battery with sealed battery, reloated r/r and greased spline and replace oil ever 6k and oil filter ever 3k miles. I do plan to replace spark plugs next week. I guess what I am asking is what maintance really needs to be done to the bike to keep her safely on the road?
