Need help troubleshooting

I have two different issues. The first one is I think pretty simple. I increased the jet and metering rods on my carb and have been getting a popping sound through the exhaust. My thought is unburnt fuel.

The second one just started today. Clicking sound from the end, turning the wheels to the right, and stopping hard will produce the sound. The full front-end was rebuilt about a year ago, K-member up rebuild. Any ideas?
