when you've had the carbs off have you checked that the butterfly in the second carb is opening OK, it can be adjusted on this screw, things can get a bit worn where the wheel makes contact as shown in second pic.

i dont think thats a good idea, if all the jets and exhaust are standard then the air supply needs to be as yamaha had it.

check for air leaks.
check float/fuel level. and get one of those carb repair kits which include o rings, needle valve etc.

yes you can get new carbs, one option is a pair of Keihin 31CR's (or 33). but not cheap.
but damn they are sexy
I dont think the standard set up is bad, I've had two previous early XT's and the carburation was perfect. but my '84 carbs like yours for sure don't work like they did 25 years ago. and unfortunately the carbs off a newer XT dont fit.
my next step is getting my carbs ultrasonic cleaned - anyone got any experience of having carbs ultrasonic cleaned?
cheers
