Just wondering when and how much , I have to rejet the stock carb.

Starting from stock build.

Do I need to rejet with removing the airbox lid ?
Do I need to rejet with removing the airbox lid and remove the stock QC ?
Do I need to rejet removing the airbox lid ans adding a slip on exhaust ?

If so by how much on all the above mods.

Trying to get the best out a stock setup. Any ideas.
Building 2 700xx motors , one stock and one 753cc MX build so money is tight till the winter.

Grind the welds inside the header, throw away the airbox lid, bout all you can really do on a stock motor. Exhaust, higher comp piston and hotcam wake the motor up alot.
