[QUOTE="Nigel Spaxman, post: 117546, member: 2907"] I did some experimenting with my bike a few years ago. I wanted the maximum oil down to the cams. I drilled the oil holes in the locking feed bolts out to about 1/16" I found out that the restriction to oil flow is the clearance around the rocker pin. The only way I ended up with to much flow to the cams to the point the engine wouldn't clear the oil out of the sump was when I drilled additional holes straight through the locking feed bolts, so some of the oil could bypass the rocker pin restriction.
