I pulled my plug after my quad wasn't starting the best and found a black end with the white tip 3/4 of the electrode was white, the rest was black. I cleaned it and put it back in...

I just rebuilt the motor with stock parts, the jets haven't changed (shouldn't be lean). Any idea why the tip of my plug is turning White?

the bikes are usually lean in stock trim, thats usually what a white plug would show, if you havent done any mods, there is still a good chance its on the lean side,
