Need some advice please............

Well since my KZ550 A2 "died" I went out and bought a 91 750 Honda Nighthawk just so I could have something to ride fro the season, while I try and bring the KZ back to life.
The Nighthawk ran perfect for 2 days. now it seems to stutter when I nail the gas. It did not do this at first. Im thinking maybe bad gas? I put 93 in it today after running out the other gas. after 20 miles, still seems to be no change...... :dry:

Help?!

Very likely has garbage in the carburetor float boles. They might require cleaning out. And so will the jets most likely at this point.

run some seafoam through it and if it still does it, pull the bowls and do some cleaning....
