Lucky lucky lucky!

Was watching WSBK this weekend and missing you fools out on the track :-( Glad to see the fun never ends!
I was due a break. I've trashed many motors before, so I was pleased to see this one hold on.

It's easy to see that this piston had been broken for a while. Again, props to bad- Austrian/German engineering. While I have nothing against Pro-X or Wiseco for the most part, I've fished broken pistons from those guys out of my engine on more than one occasion. That said, it's a race bike, and all bets are off.

Quick thinking and quality parts looks like it saved you from total destruction!!! That could have ended up far worse!!! As far as the comment about KTM=Keep Three Mechanics. . .there are a few of us out there that don't mind turning wrenches in exchange for awesome horsepower and performance!!!
I understand the consequences of my actions prior to engaging in those actions. . .there are certain situations in life where the risk is totally worth the reward.

Exactly! The stress put on these bikes is crazy, it is amazing they last more than 1 or 2 races without needing to be completely rebuilt! To that point the big boys do that anyway....

Glad it all worked out and your not buying a motor :-)
I am so busy doing nothing... that the idea of doing anything - which as you know, always leads to something - cuts into the nothing and then forces me to have to drop everything.
