Just got my tbr7! Need help!!!!

[Chineserider]

1) I want to change to fork oil as the bike seems too soft now. What is that standard preload spacer length I should look out for?
2) is the rear caliper supposed to be wiggly and loose, it seems to have some play not sure if this is supposed to happen.
3)How exactly do I adjust the clutch lever at the lever arm, any videos of this?
4) intake tube is a little bent going to carb, any way to straighten this out?

Thanks in advance looking forward to riding!
