Make sure that all your intake boots are good, tight, have no cracks, etc.. Could be pulling in unmetered air and leaning it out.

Did you piss around with that idle screw?
Maybe someone was play'n with it while you weren't look'n?

check and make sure the cable isn't too tight inside the throttle lever case on bars

How did you check the intake? Did you spray it with starter fluid after you cranked it ? Im betting air leak of bad fuel
