Don't just throw parts at it.
start simple.
You need fuel/compression/spark
swap plug leads first.
then start it, If the other side has smoke you know the problem is the ignition. otherwise
open radiator cap, any bubbles?
no bubbles means no head gasket leak into cooling system at idle.....
Then go through the carbs again after that ( I mean tear them completely apart, put all the main pieces in carb dip over night, blow everything out with compressed air, run torch tip cleaners through the jets, then brake cleaner. Buy new needle and seat for fuel inlets, reassemble and test.)
after you do all that and it still doesn't run right come back....
DO 1 THING AT A TIME. that way you can track what you changed and how it affected the bike.
