I was going to break my sled in on the hard side and then change the oil at around 80 miles. Yesterday I was at my dealer buying a new helmet, I had a long talk with the service manager. He said it would be o.k. to break it in that way but, no long w.o.t. runs until, about 300 miles. But he said 'NOT to change the oil for the first time until 500 miles. He said if I change it to early, the new oil won't let the rings seed properly. So now I dont know what to do with the oil. Do you guys think he has a good point ?....
