Okay, I'll bite....
First, all good advice (Except the sticker change....). Fresh plugs, or at least pull and check, regap to .028. Pass on the anti-seize. Can be misleading when seating and tightening. Dielectric, a pea-size glob in the boot of the coil. When seating coils, turn as you feel the clicks until it stops and bottoms out. Put your thumb on the center, and a finger to turn them back and forth until you're sure they're seated. Pull wiring connector onto the coil until you hear the wiring clip "click".
If symptom still exists, run some Berryman Chemtool, BG 44, or seafoam in the gas tank. Might have a leaking, or partially clogged injector.....if plug colors (ceramic centers) are white, or light grey, you may have a clogged injector. At this point, pull all four and send them to RC Engineering in Torrance, Ca. They rock, and will turn them around in 24 hours.
Might help if you'd tell us how many miles on motor, how long since last plug change, is it coming out of hibernation, how often you ride. Stuff like that....
