I found some time to take a look this weekend.
First, I happened to notice the bulbs within the left speedometer dial were dangling down, and when I pushed them up, the headlight and rear came on!
Further attempts to figure it out failed since it they dropped off shortly after when I tinkered more, but the fact it lit up tells me it must be some sort of grounding issue.
Can anyone define how those are supposed to be connected in and grounded? Both the left most and middle in this picture were hanging down, and both have electrical tape to make them fit in the holes better.
Do I have too much tape on them perhaps? The rubber plugs arent working any more to hold them in
I also noticed some (oil?) residue on the left side of the engine I hadnt seen before. Not sure what this indicates
The plugs look good to my eyes. As one might hope, and neither rich nor lean, but I'm much of a noob and you can tell me otherwise

The plug is a little dark, but I don't think it's a proven the way it is.
The fins on the head appear dry, so that oil may be coming out from the head gasket. The wind blowing over the motor trends to push pull from the front to the sides, so it doesn't necessarily leak where you see the oil after a ride. The tach drive seal and sometimes the header gaskets can also leak depending on what's going on.
Did you rebuild the top end? Can't remember offhand, but if yes did you ever re-torque the head?

While certainly not impossible, tach drive seal leaks are less common on the DOHC 450 for whatever reason.
