I just picked up my new XT. Put approx 2.5 hrs - 15 miles on it Saturday. Today I rode it for 2 minutes and it started to overheat to the point it boiled over. I limped it home and stopping to let it cool down. Checked radiator fluid and empty/low, nothing in over flow. No mud in radiator. Dealer is 2 hrs from my house. Any suggestion before I load it up to take back?
