It could be worse. Way back in the days of yore, Ake Jonsson was in an epic battle with Roger DeCoster for the world Championship. Whoever won this race was guaranteed to take the overall victory for the planet. DeCoster was already "The Man" with multiple trophies but Jonsson, riding for a small German factory had the lead and was going to take the championship.
Then the spark plug wire came loose, and he lost it all. The spark plug wire! That's like the motocross equivalent of being in a gun duel with Wild Bill, and losing because you slipped on a banana peel. After this set-back, Jonsson went out again later, competed in two classes simultaneously, and set a record for the sheer number of first-place wins in a season for one man (spread across two classes, remember), which I believe has yet to be broken.
Moral of the story is, don't beat yourselves up over this, it's not your fault. Apparently the metal simply can't take the amount of raw awesomeness that P250 is putting out. All you can do is go back to that big dial of P250 awesomeness that goes on a scale of one to ten, and then stencil in a little number eleven and point the dial to that! Things can fail when your awesomeness is 10/10, but that bottom-end wouldn't dare mess with an 11/10!
You might also try mixing in some nitroglycerin with your fuel, I find 50:1 is a good mix. Not nitromethane, nitroglycerin's your stuff.
