The chain case bolts that retain the inner cover to the crank case are cross drilled for wiring as standard....So, wire those. If one comes loose they can tangle with the engine sprocket and that probably wouldn't be pretty.....
Personally, I've never wired the oil pump bolts in 40 years...I guess it depends on how much you worry about these things...
The oil pump retaining bolts should have spring washers fitted....Ian
I use allen bolts cross drilled for lock wire on B & M series oil pumps. This allows you to just nip up the bolts without distorting pump body. Also makes it easier for removing anmd refitting pump with engine in bike..
