I have a picture of the drilling modification. I'll post it later today. If it works its becuase oil is being diverted down the extra hole in conjunction with the centrifugal force that is on it, instead of against it. Seems like it might help, but I think it's really hard to say. I'd rather see a non-cross-drilled crank where the oil is picked up from a central oiling bore that runs the length of the crank, or something like that.
