Today, as I was riding to work I stopped at a traffic light. and the bike stalled. I started it again and she just stalled again. She won't idle. She'll drive but I really have to work at keeping the idle going so I can get into 1st and so on.
If I'm driving and I let off the gas she'll stall.
I have a full tank of gas
She'll respond well when I turn the throttle. She doesn't over idle.

Any thoughts or ideas could be helpful

Sounds like a dodgy TPS (throttle position sensor). Search the subject on this site for more info.

I had this go bad on my 09 rocket. At that time it would idle high after the motor warmed up. This could be could be the root cause because i let the bike run a few minutes this morning before riding the 3.5 miles to work. I just road her home and without letting her get warm, I had no issue while riding home. No stalling. No idle issues.
Thanks for reminding me of this TPS.
Would this be the primary or secondary TPS?
 
Best solution, don't stop...can't comment on which TPS, but try to check continuity of both and see if in spec.
 
if u just filled up the tank that maybe your prob.
sometimes they run bad for a while.
spray linkages and wot then let snap back
spray under stepper motor boot and turn ign off and on a few times.

Check yo vacuum tubes from throttles to MAP sensor dude
Them nipple blanks too

Do you have TuneECU to check TPS / ISCV volts?

No, I didn't just fill the tank. I did that on Monday but I'm only driving a few miles to and from work each day. so the tank hasn't dropped any. Thank for the input though
