With epcos i also removed the snorkel, ai, and use a unifilter. I raised the needle with one 0.5mm shim, stock pilots and 125 mains. I can't remember how many turns out on the screws - maybe 3? I still need to get myself to a dyno to check it - it seems to run fine, but I don't know what I'm doing when it comes to carb tuning. I just followed jenk's recommendations and it seems to work... monkey see, monkey do, monkey wrench, monkey ride.
As far as black TORs you can get away with hi-temp black paint as sold at auto parts stores for blocks, headers, etc. from the photos i've seen it looks good, and it always worked on my dirtbikes. or if you've got money burning a hole in your pocket you can get them ceramic coated by jet hot.
