Can anyone offer opinions about HD's recommended service schedules and what they perform during the inspections? What I really want to know is should the average bike owner do their own maintenance on his/her bike, or fork out the money for the dealership to do? For instance, I spoke to the dealer about my first 1000 mile service. They check fasteners and change all the oils. I know I can do the oils, but what fasteners are they inspecting/tightening? Will it void the warranty if I do the work and there is no record of the work ever being done? If I use non-HD oils will that void the warranty if there ever is a problem with the drive train? Oh, the 1000 mile will cost around $400 for the dealer to perform. Any other relevant comments would be appreciated.
