It's not good to ride with the choke pulled out after the normal warm up period. The extra gas tends to wash the oil off the cylinder walls.
Now of course if your bike is so lean that having the choke out to make it run right is a sure indication of a problem that needs fixin'.
1st, I don't know what year your bike is, or how many miles it's got or if you're capable of turning a wrench... so easiest steps 1st.
Drain the carb, fill it with seafoam, let sit overnight.
Drain, pour into the tank with reasonably fresh gas.
And see how that goes.
Do you have the brass plug pulled over the idle mixture screw?
if you do, 1/8 to a 1/4 turn rich CCW to tame the howitzer blast down to a most comical poof in comparison.
Take your adjustments slow, and you'll learn from each one.
one more question, did you change anything in the exhaust or intake?
