Personally, I'd change it again, now, at 1500 miles, since you don't know how long the previous oil was in there.
After that I would not be afraid to go 3500-4000 miles or a year on a good synthetic like Amsoil with really good TBN numbers and an Amsoil filter. If using conventional oil I'd change at 2000 miles.
If you don't ride all year long, change the oil right before storage so the accumulated acids and moisture aren't trapped in the engine all winter long.
