Sounds like too much spark advance at cranking, if you can hook up a timing light maybe you can estimate the amount of spark advance you are seeing at cranking. More than maybe 15 degrees is probably bad news.
Try disconnecting the KLR and jumpering the connector:

This removes the KLR's functionality but if the KLR has lost it's marbles your problem should go away. If that does not help then maybe the Rogue DME/tuner is getting the spark advance wrong sometimes.
