OK, I have access to full scale machining equipment in my Metals shop class. I was thinking about drilling and machining my inner clutch hub. Like drilling holes in the inner webbing for oil flow and so forth. Does anybody have any input? It's the stock clutch hub out of my 00 CR125.
A while back with a YZ 80 I had, it came with some factory spec sheets that showed in detail where to drill on the inner hub for that bike. I was hoping I could find some similar spec sheets for doing the modification.
Any info in general pertaining this question is appreciated. Thanks.

Eric Gorrs book goes into detail on this modification, but i find no problem on the 01 Cr clutch.Are you doing this because it needs it or for the experience?
