    When it was over heating i grabbed the t-stat housing and it was hot on the top side which goes to the fill neck and cylinder heads and the bottom side which goes to the radiator was super cold the left side of the rad was hot and the right was cold. so that told me its not circulating the water.

    Good thinking ...I wanted your feedback first before mentioning under your circumstances of it being brand new out-of-the-box, plus happening on maiden voyage, that it could have been the dealer not purging 100% air from the coolant system.....this will cause steam pockets and can confuse a thermostat from opening up and also causing the upper most part of the heads to over-heat, since steam is much hotter than the water..in fact, I'm still leaning to that theory.....Lance

    Well i finally got my machine back. They had it for a week and put ten miles on it. they changed the t-stat and it solved the problem.

    Good to know how to look for that problem if it ever comes up for me.

    And good to hear you are back in business.

    On each head at the coolant housings will be a screw....with the engine running, loosen each up a bit and let the air spurt out...when coolant runs, tighten back up...this eliminates steam pockets in the upper cylinder which contributes to several maladies
