New Boom Vader Showing up on Wednesday - help

[Seant]

Ill keep it brief. Bought an automatic chuckus to get around town/to school. It was fun and did what I think most mopeds do to first time riders. Made me immediately sell it, decide riding automatic just wasn't for me, and thus, I decided to purchase this boom 125cc brand new from the factory. It is showing up 85% assembled and I can pick up the basic mechanic set up pretty quick/have watched countless youtube videos. I have two questions. First, I really liked the throttle play on the chucks. It gave me a little more than a quarter turn before full engagement. Can I adjust that on the boom? Or is that a bad habit? 2nd what are the "mods" aka the things I should do to the bike once assembled without yet putting any after market parts on it? Thanks my dudes and ladies!
