    Your idle region looks fine though. Its not super rich or anything.

    Take a pic of the "other maps" to see what your cold start enrichment is at.

    What mods do you have? Hoping you have an exhaust system on there...
    You could “test” your o2 by turning off “closed loop ide” to see if your idle improves.

    Edit sorry I saw you posted your mods.

    Hey! I think the problem is cured, warmed up the bike, reset the TPS again. Then let the bike cool, and started it up, no more stalling, runs great.
    Hard to tell what actually was the problem, maybe just the TPS, but now it runs like a charm also, thanks guys for all the help.

    Nop, i changed to new plugs, and the problem got worse. Put back in the old ones. Maybe there was a bad connection at the coil somewhere, hard to tell. Took the bike out for a ride, and it runs noticeably better. And no more backfire in the exhaust on decel. Got the new O2 sensor, don't know if need to change it now.
