    2007 800r with what looks like a detoed piston?

    If you never had a updated Short Block installed yet, NOWs the time. The inner MAG beraing came apart and the cage went through the engine. Make sure you replace the head if there is the smallest nick in it or it is sure to detonate from the hot spot from the nick.

    Coolant Leaks

    Check the lower rad hose under/behind the recoil, the upper hose under th oil tank, the "T" fitting behind the air box. Chances are it will only leak when its really cold due to the aluminum contracts in the hose and the leak stops verry shortly after the engine is running.
