This is highly debated.
I did a mix, the first two-three hours I think I took it relatively easy, only going full throttle once? But then I had a friend visit, and together we are probably 400 lbs? That put more of a strain on the engine than I wanted, but didn't beat the piss out of it.
I think you'll be fine. Some say take it easy and follow directions and the longevity will be there. Others say ride it like you stole it right from day 1 and seal everything up nice. I met halfway. Beat her, but also went easy.
