My '05 America started blueing the left pipe (double-walled remember) right out of the box. I took it to the dealer and he told me that he set both mixture screws to 2 3/4 turns. The bike is stock except for AI removal. The left pipe is getting bluer all the time and the right is fine. The bike also seems like it is running lean or something. It has a slight hesitation under normal driving conditions. It runs better and accellerates better with the choke on even when hot. I mean it doesn't really miss or the like but just seems to stumble ever so slightly when I roll the throttle on. It's almost like I have to give it more throttle than I should to get it to accellerate. I tired opening the mixture screws a touch more with a flattened .22 casing but can't really tell if I am really turning them. Could the carbs actually be out of sync instead of a mixture adjustment? I hate to keep running this thing back and forth to the dealer all the time. But the blueing pipe really bothers me. Sorry if I am beating a dead horse here but the dealer may get sick of hearing from me and start blowing me off. I want to put TPipes on it but it may run worse. Any ideas? :???:

If it were mine, I would ask the dealer to set the pilot mixture screws using an exhaust gas analyzer (sniffer) rather than setting them both at a set number of turns. I would also ask him if he would balance the carbs since there is something different between the two cylinders.

When you say that "it runs better and accelerates better with the choke on even when hot", is this at highway speeds or slower around town speeds?? How much are you choking it?? This sounds like you are running leaner than I have experienced with my '03 T-100. On this new of bike, I would probably talk to the dealer's mechanic and see if I could get him to test ride it with and without the choke partially on. Make sure the dealer is aware of your problems--I don't believe what you have described is "normal".

I personally would not think of silencer changes, etc. until I had this problem resolved.

The uneven blueing is probably an indication that the carbs aren't the same. This isn't uncommon with these carbs. The mixture should indeed be set with an EGA instead of just turning both mixture screws out a certain number of turns.

The hesitation you describe is likely caused by a lean condition in one of the cylinders, probably the one with the blue pipe.
