Hawk 250 PE28FL Jets?

I installed a PE28FL Nibbi and the stock main was a 112, I changed it out to a 110...now I'm thinking I should have went with a 105?

The nibbi and the matching Nibbi Air filter are the only mods that affect performance on the bike.

I live between 500-600ft above sea level

Bike sometimes has a hard time starting up for the first time, especially if it's chilly out (40-50 degrees), but after it's warm starts up fine every time.
I know nothing about bikes or carbs. does this sound like a jetting issue?

Also, is the plunger a "start assist" on this carb? So I pull it up to start the bike, then push it back down after it's running a minute or so? Coming from the stock carb that has a lever I'm a bit confused.
