I know this is a common problem with racing motors as I have lost two motors to this now and other friends have also lost motors to rod failures and it is always this number two rod that fails on the big end. I have been told a reason for this is because the way KW oil supply is ran. Most everything is ran off the left side which causes oil starvation of the number two rod? What if anything can be done about this. I am just about ready to throw in the towel with KW motors.
