My only advice is to go easy on the engine for 1,000 miles changing the oil every 200 or so. After that it should do 60 mph easily every day. These engines will do 75 mph-once. The metallurgy might be better these days but my 2009 with the same engine will fly but it's not built to be flogged. If you keep it below 64 mph it will last forever.

I read somewhere, maybe here, that even with water cooling the oil heats up, breaks down and takes the engine with it. Ridden moderately it isn't a problem. If you flog it the head gasket will go first and what follows isn't pretty.
