Lol.........!don't get too excited yet. i've also had a brand new motor that almost made it 6blocks to the liquor store before the main bearing exploded and seized the whole thing.
Well said......Dasmailca brings up a good point. These engines can run for hours under normal use. Days, maybe? Probably.
But there are other factors involved in whether or not you can be riding all that time. And loosening fasteners is one of them. Once the components start moving around you'll find yourself by the side of the road, tearing out your hair, cussing, etc.
Don't let us frighten you; it's not all that hard. Takes a little practice is all. And awareness.
