Oh, you mean like this bolt treatment on my KTM SMR? The whole bike is like that. The clutch basket is so drilled out, it looks like a spider's web. In the lower left, you'll see the titanium clutch bleeder screw that I made (has a rubber cap).

I thought about shaving down that pulley nut, but decided to leave some extra meat on it since I knew it would be subjected to an impact wrench.
