Want opinions on break in. Follow the manual, ride it like I stole it, or somewhere in between? It calls for the first oil change at 600 miles, then every 3500 after that. I had planned on switching to synthetic at the 4k mark....but then I can say for most of my bikes, I ran the factory fill til 1k, then switched to synthetic, and none of them ever had any problems. My Goldwing, I followed the manual and changed the factory fill at 4k, then it's been 10k intervals with synthetic ever since.
