Sounds cool about making the hole bigger, which im really curious to see how long it will last you. Could be possible about the reason that you have listed that could cause the Crank pin to break, but why does it also break when the engine is brand new from the box and running on the first tank on the track with rich settings after coming of the bench after 3 Tanks of idle? i would rethink about drilling that hole bigger. But good luck anyway and keep us posted, like i said im intrested and i hope it works. Just might be another improvement that could done.
Cheers
