    going by that pic ^ it looks like the exh cam outer sprocket has spun on its hub ? they are only a press-fit. bent valves will be the cause of your loss of compression eh

    looking like oil starvation eh, that rear exh cam is probably the last gallery in the oil supply (and probably the hottest area of the whole engine)

    Yup I was just thinking the same thing from the burn marks. It either got too hot or had not enough oil or both. How many Km/Miles are on the 9?

    What's not enough oil? As I've posted before, a friend had been having shifting trouble. I told him bring it over, let me change the oil. It had been over five years since the last one. When I drained the oil, got 1.25 quarts on the drain. 1.25 out of a four quart motor. Just Wow! Still runs to this day.

    Its a 2011 bike not sure how many miles but less than 20k regularly serviced running semi synthetic oil.
    Guessing cam seized initially then gear was spun off cam during diagnosis of problem when engine was restarted.
    Rear exhaust cam is at the end of the pressure oil feed galleries for sure but those grooves in the cam surface?

    My 2006 is less than a hundred miles away from 36,000. If it wasn't going to be a wet weekend, I'd pass that mark this weekend. But alas, Mother Nature has other plans.

    Check to see if the piston hit the valves and damaged them. Pretty common when a cam chain goes.
