Yes, seriously ripped off if you are talking about that much for the labor only. I am assuming that you had paid for the center stand and engine guards and are talking about $800 for labor, oil, and oil filter. Assuming at the most, and this is really generous, one hour to install the center stand (a shop should be able to do it in a half hour at most), and one hour for the engine guards, and again, at the very most $250 for the 500 mile check (my dealer here in TN charged $135, including a gallon of Mobil 4T and a Triumph oil filter), you were overcharged by a huge amount. I don't know your labor rate there, but let's say that it's $100/hour (again, extremely generous, but it is N. California), you are talking a maximum of $100 plus $100 plus $250, or $450. A dealer charging that much here would be out of business quite quickly, but you are in a much higher cost of living area. Even accounting for that, you need to talk to the dealer. Did they give you any idea of the cost before you had them start work? How much the 500 mile check would be, and the labor estimate for installation of the parts?
