Welcome aboard! Make sure you are using the right spark plugs. I've heard from a few others with the same bike coming with the incorrect plug.

Thank you so much for responding! My dad suggested that as well. So I put in some new NGK CR8E plugs. Found them through some Google searching, and they were recommended. However I still have that issue

That is correct. It takes a NGK (1275) CR8E Standard Spark Plug.

if it's fuel injected, it shouldn't need a CDI. If it's the same cylinder, you more than likely have an internal problem. Try adjusting your valves. If that doesn't work, and you have access to a borescope, look inside the cylinder to check for problems. It's seems like you may have lost compression in one cylinder.

OK, thank you for confirming the correct spark plug. Also thank you for the info about the CDI, and that explains why I couldn't find anything like the boxes online mounted anywhere on the bike

Venom motorsports emailed me. Found the problem. One of the coil packs was wired wrong from the factory. It finally just burned out causing my recent issue. It also explains this weird electrical issue I was having

Are you still having the problem?
It might actually be the crank position sensor. I had a similar problem where one cylinder would not fire and occasionally not want to start but once running and driving it was somewhat fine. I check that the ignition signal wasn’t triggering on one output from the ecu and initially thought it was a bad ecu but the ecu can only fire if it knows where the crank is in it’s rotation and it was getting occasional bad signal. Swapped out the sensor and now it’s perfect. Before you spend any money on a problem be sure that is the problem or you will spend a lot of money replacing perfectly working components.
