I checked the tank vent.
No on that
I looked over the electrical and checked the coils. They don't seem to be getting the best contact.
It started raining so I didn't get to clean and tighten the battery terminals.
I also opened up the carb tops, and the rubber is seated properly.

I pulled the plugs and verified that it is running rich now from changing out the carb rubbers. That is the ONLY change I made to the bike.
