Primary cover is not very hard to remove. Drain the oil, loosen the chain adjuster under the primary, remove the bolts and shifter. Pull the primary cover. Fix the pin, or punch out. Reinstall the cover in reverse order, remembering to pull the chain inspection nut, and adjust the chain tension to spec. Nothing in there to spring out and fly across the room, just a oily mess to have to clean. To put on a bench, you will have to remove the clutch cable, and it is pretty easy, once you see it in the cover. If you remove the cable, you will have to readjust to get the clutch to work properly. Usually just cable adjustment, unless your clutch needed adjustment to start with.
If that is to complicated, you could always redrill the peg mount in another spot, and match the hole up to the cover and install a new pin there.
