Exploded Yamaha!!!

So My bike decided to let me down on my last race day at Hollister hills. With a big backfire and little pressure n the kickstarter this piece of the engine case decided to exit the place it was suppose to be at to make my bike operate properly.

Here is the area of the case where the piece is missing. Right behind the kickstarter shaft. It is part of the Right Case Engine half.

Here is another view of the case where the shaft would have met with the outer shaft housing. The housing has a 'cup' in it to hold the shaft end.
More on this later...
