Troll, I hear you on the voting cage drivers :P  Better keep 'em happy or they'll vote us off  the road.  But I don't like rude bikes either – especially when I got my driver's window down and they're sitting on my left.  I think I'm going to go with Retrorider's advice – first get some baffles in there, then figure out what the carb wants.  I'll let you know how it goes.

Tfrank: To comment on one of your questions. Putting in baffles on those straight pipes and getting some backpressure back on the engine will help. I have a stock carb on mine with a roadhouse exhaust that started with nothing in it. Bike ran awful and was loud. After a combination of a correct baffle and then a smartparz baffle, sound is right and the color  of the exhaust darkened again, and the popping went a way and there was no stumble...so you can move it in the right direction with baffles.

Cannot disagree with Troll either....if you re-jet, you can tune to your exhaust.....but IMO you have to start with baffles or a different aftermarket so you can get some back pressure on that engine.

I sure wish noise really equaled power, but it doesn't. The stock exhaust and the stock carb jetting are EPA certified, and hence, both quiet and lean. Even with all the correct parts, there is still an off-idle lean condition that the EPA seems to like, but everybody else hates. Get a DynoJet carb kit and rejet. This will fix the too lean condition, and please do something to quiet it down. There are lots of potential voters and non riding citizens who do not appreciate motorcycle music...

Hey there my first post on this, as I just bought an '06 800 drifter.  So this bike has shotguns with no baffles, I got to say way too loud for me, and I'm already looking at picking up some baffles for it.  I really wish it still had the stock exhaust, with that fishtail on the end, but the PO ditched it for some reason.  Anyway, the thing is running way too lean – apparently they didn't reject the carb for these open pipes -- so it really doesn't want to take the gas at all.  Now my question is this, when I put baffles in, should that get it close enough to the OE back pressure that I don't need to do any tweaking of the carb?  In other words, I want the bike to run richer than it does, and at the same time I plan to make it a little "constipated" ;D and I want to know if that action alone will make it perform like I want it to?  Thanks for all your help.
Tom
