I'll never be able to buy another one so I need to make this one last. It had 17K on it when I got it and it's about 38K now. All fluids and the oil filter are changed at 5K or less if I'm going to be on a big ride. (The air filter is a K&N and it gets cleaned and re-oiled).
Something that the corporation I worked for never understood was something farmers have known for years and years and that Oil, Grease and Regular Maintenance is a hell of a lot cheaper than Parts, Labor and Down Time.
