And the next gremlin is...

Went to get the bike safetied at crappy tire today, and unfortunately it didn't pass sometime between last night and today the horn has stopped working and apparently the brake light is intermittent (not that I've found but whatever...)

The big issue is now the bike doesn't run. The numpty that did the safety left my key in the right position and killed the battery. We boosted it and got it running but it backfired hard. Started to ride away and got all the way across the parking lot before it sputtered and died. Long story short, my left two cylinders aren't getting spark and my right two are. I know nothing about points ignitions but when I lifted the cover, everything was clean and shiny.

Everything ran like a top this morning, now I don't know where to start. I did clean the connectors under the tank and put some dilectric grease in there

You need to charge the battery first. Might be dirty points or fried coil.

Figured it all out

Horn - bad ground when I put the handlebar control back together

Brake Light - Guy must not have been pressing all the way down on the rear brake, thus not engaging the stop lamp

Not running/only getting power out of half the coils
- Idiots at crappy tire flooded my engine and wet fouled my spark plugs. Put a spare set in last night when I couldn't find any other reason for the problem.

My only concern now is what caused the wet fouling of my plugs, user error or a problem in my carbs...

Bad connections.

That one bit me too: swapped chrome bars for a painted set and the horn stopped working. I took the area under the switch assembly down to bare metal and all is well.

If you need to you can easily adjust the sensitivity of the brake light switch by bending either end the little spring that connects the switch to the pedal. Ed

Instead of bending the springs, can't he turn/adjust the brake light switch adjusting nuts so that it comes on correctly?
