I'm going to chime in on this discussion, all be it old, for the sake of those who maybe fishing for auto decomp starting solutions:
Have a 01 fc550, factory auto decomp, lever and kick starting hardware; until such time I removed, yes removed the cable for the kick starter tie in to the decomp was I able to successfully kick start the bike, usually 1-3 kicks when just past tdc.
The cause, the resistance created with the cable unto the kick starter was just sufficient to create an insufficient kick start. I spent many of hours reading starting woes forum discussions only to finally find someone else having removed the kick start hardware as a cure.
