Ok, so update time. Since it was only -11 today (without windchill), I decided to do some work on the bike. And the weekend is supposed to be around zero too, so should get some shit done!

Today I put on my clip-on handle bars, and the chrome headlight brackets. Very sexy. Ran into a problem though...

When I was putting on the left bar, I had to take off the left fork cap and bung the thing on with a hammer and wood block. Well it's on fine now, but I have no idea how to put the cap back on the fork, as it's pretty hard to compress the spring and turn the cap at the same time. The hex socket in the cap is 20mm, but I looked around town and no one seems to carry a 20mm hex wrench or anything!

I tried fashioning one out of an old hockey stick, and it works for fitting in the socket, but it's still very hard to get it to go in the fork.

I feel like the hugest noob in the world here

Yep, once you jack up the front of the bike so there´s no weight on the front wheel, you should be able to get the cap to start threading in.

How can you tighten the cap when you dont have a 20mm hex wrench? Try this: get a hex head bolt, with a head that measures about 3/4 inch (or about 20mm) across. Clamp the threaded part of the bolt real tight in some vice-grips. Put the head of the bolt in the cap, and use the vice-grips to turn the bolt.
