Bandit running rich, can't be fixed?

i would put off the dyno until you have fixed damaged parts and set everything back to factory settings.

if the muffler is standard....?

start with the air filter, clean or replace ( you can put in a performance filter if your muffler is not standard ).
check for any obstructions in airways.
if they look damaged or you suspect they are, replace main and idle jets with new factory spec.
set neeedles at factory spec position.
reset idle screws to factory spec position ( the ones bottom of carb, not the throttle stop ).
put in factory spec plugs.
give all carbs a visual inspection when doing the above to check they seem the same. check floats etc.
after this it should run well. provided the throttle stop/idle is set right.

is the muffler standard ? if it is not, you will need to dyno it after you have done the above.

I dont generally need to use the choke, if i do put it on it makes it rev alot higher, thats about it
