Hey, MasterM3 -
1) What's wrong with a nice view of your elbows?
There are LOTS of options. If money is no object, I'd get bar-end mirrors for CRG. Napolean also makes nice mirrors. I have crappy Emgos that are better only in that they are black.
2) Any can with a 2", pinch style inlet will work. you just need to hack the old can off (if stock) and put the new one on, really.
3) Need more info. Where are you? What's the weather like? Other than the clean/tune, have the carbs been messed with? Your idle screws could be out too far, maybe?
4) (Unsolicited) Be careful out there and WEAR YOUR GEAR!
Good luck with your new ride!
