on the Saturn,,...It most assuredly is the IAC.....on doing DPFI  for any
engine...the hard part is the mechanicals...getting the injectors mounted
correctly, and a t-valve (air valve) in place.....if the bike is air cooled
engine, you mite have a problem with an engine temp sensor,   also with air
cleaners-filters,   all of this not so easy for the home mechanic on a bike as
ALOT of metal fabrication is necessary.....GENE
