So my bike ran for about 5 min, then died on the side of the road. It's got a blown 30 amp fuse. When I replace it, it blows the new one the moment I reconnect the 4 pin connector. If I unplug the connector from the regulator/rectifier, it powers up and starts fine. Nothing looks burned. Any ideas?

The rectifier diodes can short and draw great amounts of current. Sounds like the problem.
If no work has been done to the wiring otherwise, I would replace the regulator/rectifier.
Check the winding in the stater first, just in case they shorted.

Can I check the stator without opening it up?

Yes disconnect the 3 yellow wire connector and measure resistance from each wire to ground. It should not have any to ground.
You can test the complete charge system wiring this way=
