I have a 07 roadglide, just filled it up with super and now its starting t shut down on me when I let off the grip. What could be some problems to check for

 

Idle Air Control dirty .... probably first choice to look at..... my 07 Street Glide did the same thing every once in a while....... spray some carb cleaner in the IAC hole..... just be careful not to get it all over everything. If it keeps on... you'll have to go up the line... TPS would be second idea generally I believe.

 

These bikes call for Super anyway, so I don't see why that is significant. But if you suspect that the fuel was/is bad for some reason, then I would suspect the fuel filter. That's assuming you have checked the idle controls and other sensors for proper operation.
