Rotax 717 Carb Main Jet Question

[orbit398]

Have an HX 717 motor, bored it out to 1mm over. That's as big as it can go. Wondering if I need to up the Main Jet due to the cc size increase. I currently have the stock 137.5 jets. Not sure hoe to go about calculating new cylinder camber volume and a matching larger jet. May not be an issue but just wondering. thanks for any advice.
