For a 150cc GY6 what is the proper I.D. of the connector? Some aftermarkets say 38mm, some 44mm and others 45mm. I was considering just grabbing the 44mm and figured it would fit if i moved up to a bigger than stock carb eventually.

Your best bet is to measure your carb. The stock 150cc carb I have measures 44mm. If you go to big it won't titan down and you will drop your air filter on the road somewhere.

That's part of the issue, I don't have the scoot yet. I was working on eliminating a couple things right off the bat. Supposedly this motor is high-compression so I was going to grab the breather, a k&n and some jets so I was ready to go after pdi.

These engines are NOT high compression. They barely have compression. Spend your time learning about the scooter rather than throwing parts at it.. you don't even have it yet.
Contrary to what everyone wrongly believes most scooters are well engineered and run decently with stock air filters etc. Changing the air filter and jets is an art.
If you want performance improvement, tune the CVT first to your taste.
