I have a 2007 FXSTC and recently it has been stalling out when it is hot outside or temp of bike gets over 200. Dealership had it for three days and couldn't get the bike to stall or figure out what the problem could be. I had it back one day and ran it in 78 degree weather bike temp got to 227 and stalled out several times. It will backfire through the exhaust also. When cooled down below 200 degrees it will start back up and run fine. Any ideas as to what is going on. Or anyone else experiencing the same problem? Bike is stock except power commander, exhaust and high flow.
