The owner's manual for my FJR says to change oil every 3000 miles.
I just got the bike last summer and have changed the oil and filter at 100 miles, 600 miles, and 3000 miles. (I also change gear oil in the differential at every oil change.)
I currently have about 3600 miles on the bike, and the oil already looks very black. I am running Yamalube semi-synthetic.
Should I:
1. Go with the owner's manual recommendation?
2. Go ahead and change the oil?
3. Split the difference and change the oil when the odometer hits 5,000?
4. Quit worrying about it, and have a drink?
