i checked coils..plugs..everything..its not that man
by check coils did you replace them with a set of known working ones and try? just checking resistance wont always let you know a coil is bad, you would need to simulate engine working conditions and check the coil at that time.
Also when you have your throttle fully open, what number is the TPS throwing in the diag?

As Luke said: Coils are suspect #1.
As Cheefa Said: Throttle Position sensor is Suspect #2

Both of these are common culprits on 2nd gens (particularly the '03)

Also, what mods have been done to the bike that might affect electric or fuel delivery? How is the charging system? Are you having any trouble starting the bike?
