just assembled the bottom end and cylinders on my 1052. installing an 1109 ape kit and used carrillo rods. once the rods and cylinders were installed I rotated the crank and the rod bolt on the #3 cylinder comes in contact with the oil passage to the input shaft bearing.(see pics) cant grind clearance or shorten bolt head( would throw out crank balance.) called Carrillo and they have no answer. anyone else come across this before.
