One question. Are they the Vitos power pistons with the reliefs on the edges of the crown?

If you’re having trouble tuning stock carbs, you’ll melt a motor with lectrons. 

I could help ya, but I’ve gotta know the piston info to be sure. And your porting info was vague. So if you don’t know your own bike, how can folks give you proper info? The Vito’s power pistons simulate  porting, so they require more fuel.  If you’re unsure and want a guess in the wind, throw a 30 pilot and 310-320 main in it and work down.
