First, clean the carbs. Then check the sync, then check the air screws.

If it's bogging when you punch it from 1000 RPM, there is no way to fix that, you should just feather the throttle until it's around 3000 RPM before punching it, that way you get a better start.

When the engine is warm, it's supposed to idle lower then when it's cold, my '97 (with '98 engine) XCR 440 idles around 3000 to 3200 RPM and when it's warm it idles around 900 RPM.

Yes, Triumph is right, you should be able to set it wherever you want. At idle, I'd guess the pilot jets probably have garbage in them. usually a shot of compressed air is enough to clean them out, but sometimes, depending on the junk caught in there, you have to soak them quite well before it becomes completely clean.
