I'm afraid of headset and stem adjustment...
I noticed my trail bike's integrated headset was clunk-clunk and could feel and see the cone spacer under the stem moving around when I rocked the bike with the front brake applied (it wasn't from play in the front suspension). So I loosened the stem bolts then tightened the top cap bolt just a teeny bit, and now the play is gone and it still seems to turn left and right okay and smoothly.
The only thing I'm afraid of is whether or not I have the stem bolts too tight or too loose... No torque wrench or one of those preset torque keys. I just used the short end in the bolt heads and turned it with my fingers real close to the bend in the wrench until it felt pretty tight. Is this pretty close to being the specified 5 n-m torque (that's printed on the stem)? It's an aluminum stem and steerer, so I should be okay, right?
Luckily for some reason I decided to check the headset with the rock test because I also found that my front quick release was extremely loose! Dodged a bullet... I will sleep better if y'all can learn me if I did the headset up right too.
