Hi guys,
Just received brand new S&S flywheel assembly, 4inch stroke, early twin cam style. I noticed that there is NO OIL HOLE in the small end of connecting rod. Is it normal? Should I drill it or leave it as it is?

Received email from S&S tech support:
"There are no longer holes in the small ends of the rods. Through testing we found the were no longer needed"

All clear now

I might drill them anyway. 1/8th inch with a 3/16 chamfer. The piston jets do blow a lot of oil up in that area, but its also a high wear bushing when you push the compression up.
