Looking for some information on the subject starter. Was the original starter 31618-06 on my '07 Ultra a 1.2kw unit? Anyone know how to identify the 1.4kw high output starters, other than the bolts on the starter housing on newer units versus studs with nuts on the older style? Doesn't appear to be part numbers on the units anywhere. Also, what was the "A" change on the 1.4kw units, new clutch? Thanks for any and all information.
