Hello, I have a 2019 Kymco Agility 50 with 100cc Big Bore kit with deleted air box and aftermarket pipe. I just bought a 125cc carb to put on it and I am needing suggestions on what size main jet to put in it. Any help would be appreciated. Thanks!

Welcome here!
Not an Agility but maybe link beneath gives you some ideas how to jet.

The standard Kymco 100cc (e.g. Sento-100) with 20mm carb has #35/95 jets. The same jets for either Kymco carb or the Keihin CVK carb. The Kymco carb is more difficult to start, and the Keihin starts OK, but it's lean at top speed WOT (~9,000+rpm)(90km/hr) so some adjustment needed. If it's missing at WOT, slow down. Don't push it until the jetting works. That is, when tuning, have a selection of Keihin jets at hand! They're not expensive, from www.jetsrus.com for example. Kymco jets are not easy to find, but they're out there.
