DC4          # 10 jet - Have only seen 2 since 1965 and I have no idea of fitment !

DC12      # 4 jet - L1963-1965 Sportster XLH,XLCH ( also used on 1969 military XLB )
All except DC2 are the same body. NOS bodies actually were shipped blank and the dealer stamped the number needed on them.
I have owned a number of these NOS bodies over the years. If you have a larger bore body using a 9X throttle disc, this is from
the modification bulletin Harley put out on the DC carbs many years ago. I do have a copy of this and it is posted here.
Differences on all except the DC2 were in jet sizes, needle & seats, bowl lettering, etc, all minor. If you go to our Jet page
you can see which jets fit which models. NO - they did not make a DC3, DC5, DC8, DC9, or DC11 ( "real" DC11 "race" carbs
were modified versions of other DC models as per the race modification bulletin listed above, whether by Harley themselves for
the XLR or by a particular dealer. Linkert did not make DC11 carbs as such, and you will also find these mods on every model
out there except DC2, a few well done and re-stamped as DC11 ( probably by Harley for racers) , some very poor quality backyard
jobs with the idle ports ruined, so look them over carefully. )
