I ran the bike about 200 miles with the motor oil installed by the factory. I felt a little guilty when I changed that oil, since it was so clean.
I replaced the factory oil with Mobil, Delvac, 15W/40 motor oil, and rode the bike until the odometer reached 900 miles before I changed the oil again. I will ride the bike until 2,000 miles, before I change the oil the third time. Thereafter I will change the oil every 2,000 miles.
I
always use 15W/40 motor oil in
all my motorcycles, with excellent success.
