2023 Vitacci Tank stalling with less that 400miles

[Purpose]

After putting the bike together, the first issue I noticed was the small fuel leak on the air box. The bike was running fine, so assumed this was normal. After the first oil change at 300mi, the bike took a turn for the worst. Constant stalling and sputtering under load. Have to wait before trying to restart, and when it does, it will rev to 3k. Seems like a fuel issue or the cdi. Thanks in advance for any tips.
