A good source for bearings and races http://http://www.allballsracing.com/
. I would replace the races at the same time. See if you can borrow a bearing/race puller.

Then Renner showed up and was kind enough to take my bike for a spin and give me an opinion on it's performance.
Between the 2 of them they gave me oodles of fantastic advice and tons to think about! I can't thank them enough for meeting with me and helping me get started (AND! offering further help!). I was blown away.
Key take away notes: (there was more of course, but I'm focusing on these 2 for the time being)
Mike is worried about my transmission - I'm going to try to change the fluid and check the magnetic bolt this week and report back
Renner is worried about my steering bearings (and boy, after comparing Mike's 100 to my 80, my steering bearings are CRAP) - so I'm going to try to get some parts and get ready for a complete fork/neck tear down...
