Post subject:  Breaking in a rebuilt engine

Hi, I have a 74 CR 250 I'm finishing restoring and I was wondering if anyone has proven results on how the best way to break in a rebuilt 2 stroke. My engine has all new bearing, seals, fresh 2 over bore, and new wisco piston. Also should I start with the stock carb jetting or does it need to be changed because of the overbore.

Thanks for any help,
Matt
