Put together my new Hawk, now some questions..(pics)

[Chito]

So I put my Hawk together and it was painless.. took my time and put new fresh 15WT fork oil in as well as some Rotella T4.. those fluids it came with were pretty murky and gritty, looked like fine coffee grinds settling. Good call there..

A couple things.. FYI my bike says Jun 2018 manufacture date.. The RPS owners manual says the bike comes with O-Ring chain, also the chain is tight but I also don't intend on taking a 100 mile cross country ride till I put the bike through my own trials and Quality Control.. from what I know the chain should loosen up after a few rides.. should I bother adding slack seeing that I'll probably have to reduce slack after a few rides (is that the reason it comes tight in the first place?)

Secondly... I had one issue. The pin that holds the rear brake pedal assembly was nowhere to found so I'll have to find something to complete that before I get to test ride... (SEE PIC)

Other than that.. everything looks ready to go. I'm going to get it going and riding stock configuration before I start tweaking and adding upgrades. Would like to get a feel for what this bike is like out of the box before I start tweaking things, I like to get an understanding of what baseline is. I'm in Idaho and this will probably spend 80% off road since our state is mostly fire roads and back country/mountain dirt roads... keep you posted.
