Update

It wouldn't start when I tried again yesterday, so I did a few things. I pulled the float bowls off of the carbs and cleaned the junk out of them. I drained the gas (it was orange) and pulled the petcock and cleaned all of that out. After that, it fired back up. I was able to shift through all of the gears, so that's exciting. I'd like to get my tires ordered today, and I'll need a tank cleaning kit as well. At that point, I can start riding it around. I'll probably head to the parking lot at a park nearby to get the hang of it.
