I seriously would not change the oil on any new engine until the recommended intervals. The first oil fill from the factory tends to have more moly and assembly lubes which are beneficial to the proper break in of the engine. So, I would leave it in there till at least 5 thousand miles.Just take it easy first 1000, vary speeds and gears. After that have at it. What I have always done. Works OK for me!
I would change the oil at 1500-2000 miles.
