I know the first 1000 mile service is important but the dealer wants a lot of money. This is my first Harley. I've owned other bikes and I can do oil changes and have seen enough YouTube videos to be pretty certain I can change the primary oil too. So what else do I need to do for the first service if I decide to do it myself? I've looked at the manual and most everything seems like checking bolts, tire pressure and lubricating the jiffy stand. Any help and advice form a seasoned Harley Sportster veteran would be greatly appreciated.
