There is a guy on eBay that does the mod...he puts a jet In where the hole is drilled. He also sends a new 07 and up pump . $200 for evrything

I have personally done this mod to a 2004 MY YFZ450. It does require the oil pump from a 2007-up as the extra "port or passage" will greatly reduce the oil pressure thus not making the new port or squirter less effective or not effective at all.
