These new bikes sure need a lot of work just to expose the areas for maintenance. I'm doing the valves and plugs on the tiger and can understand why a dealer charges $700 or so. I'm using the money I save doing it myself to replace the cam chain, tensioner and sliders. I figure its got a little over 100k miles, changing those out is cheap insurance. I am also shocked at how dirty the air filter is, supposedly about 1k miles before I bought the bike the air filter was changed as well as the coolant and brake fluid. Coolant looks fine, brake fluid is clear, but the air filter is terrible for being new about 3k miles ago. But I do have a uni pre-filter to add that replaces the snorkel.
