I ran a wiseco crank. It blew the lower rod bearing and took out a very expensive big bore kit I had on my kx. I have yet to get repaired. I will not run a wiseco crank ever again nor tell people to buy them. I've seen more wiseco crank failures over the years I can't count them. From actually breaking in half, bearing failure to rods snapping. If there is a failure with the cranks, wiseco will cover the repair and buy a new engine if they determine it was the crank. Which takes a long time to determine and there is no guarantee they will cover it. So run them at your own risk.
