I would think there would have to be a code but there is nothin and I could ride the bike from my house to Daytona FL and if I don't stop, runs flawlessly. Even when I do stop its a crap shoot if it will shut off sometimes it will go for a week and not have a problem and sometimes at every stop sign it acts like its loading up and just shuts off, Hit the starter button fires like nothing ever happened..

As you probably know, the crankcase venting is dumped into the intake behind the air cleaner.
This oil-rich vapor is what causes a buildup on the intake and on the IAC sensor.
With the air filter off, wipe a clean rag in the intake and around the butterfly flap.
That same gunk is on the IAC sensor which is mounted right above/behind the butterfly.
Look in the intake tube, at the 12:00 position.
You'll see a small hole.
Shoot some carb cleaner up into that hole.
Don't be stingy with it.
Then button it up and ride.
This is why I ended up adding an external breather/catch can; to avoid disassembling and cleaning the intake every 1,000 miles.
Has a brand new IAC in it less than 300 miles on it
After looking into some of your guys answers and researching the symptoms others are having I Just ordered a new Temp Sensor. Everything I have read and seen the temp sensor is causing 99% of the same symptoms as I have only difference is I don't have a code. Should be a couple days till it gets here and I get it in and then who knows when mother nature will let me get it out and call it problem solved.. When I do ill def update and I do appreciate all the replies and pointing me HOPEFULLY toward the right direction!!!
