are you letting it sit and idle alot?or starting it, lettin it idle then shuttin it off again? the efi models start in a rich modethat doesnt shut off till engine warms up and computer shuts it off, when you start it cold, let it run for a minute or two then go ride it till its warm, dont let it sit and idle long or idle a little then shut it off.

There is no O2 sensor. The t-bap sensor may be bad (unlikely) or the throttle position sensor could be bad or out of adjustment.
