Check with yuor dealer first but I'm pretty sure you should break it in with regular oil at first. A friend bought a brand new XC 700 this year and was told to run his first 100 - 150 miles on regular oil, then syphon it out and run your synthetic oil. Like I said Check with your dealer or performance shop first
catroy,
go with what you are going to use from the get go. my experience with switching oils even different brands of the same viscosity has been a horror story.
