I'm not a cheap person but I also don't like spending money when I don't need to. My C14 has 1200 miles. I changed the oil at 125 miles and I was going to take it to Kawasaki to get the oil & rear end fluid changed by them. I'm afraid that if I don't have them do it I might have a warranty problem down the road.
It wouldn't be a bad idea to record what the oil looked like when you pulled it out either. Run a magnet through it to check for large metal particles. If possible record the other adjustments that you made while you were doing the service.
