I dropped my bike off for the 4,000 mile service and they tried to charge me for a valve adjustment. They didnt even have a maintenance schedule for the Stryker and instead tried using the V Star 1300. I made them pull up the service manual and show them how much they dont know. I think I could probably do everything myself but for me it is kind of piece of mind. I am not sure if I am doing all of the checks correctly.
