There's allready a 12:1 in it and running strong. I posted the pics because there was some talk of octane and jetting with an 11:1 piston. This one was running on 91 pump gas and I think that was the main reason for the problem. It's hard to see in the pics but it looks like it cracked and then developed the small hole.

I wouldn't recommend it. You might get away with it for trail riding when your WOT for short periods of time, but drag racing up long dunes and the problem the stock raptor carbs have of not flowing enough fuel for the bigger jets, you'd be asking for problems. Low octane and a little lean is a bad combo, especially on long runs.
