After seeing a bunch of crappy aftermarket mirrors I found the Halcyon brand at Revival Cycles in Texas.  Made in England and all stainless with a three piece wedge mounting system I ordered a pair.  They arrived yesterday and were on the bike in a few minutes.  Wow!  High quality, great field of vision, reduced vibration and they ratchet up and out of the way if needed.  I love them!  

I installed them last night so I could head over to the Inn at St. John's for the Concours d'Elegance America.  They have a stunning C&C Saturday morning where I met some friends.  Put on about 50 early morning miles.  On my way to the event I passed the HD dealership where I took my MSF classes and saw that they were running a class.  On the way home I stopped and talked to me teacher and the head of the customizing group at this location who came out, saw the bike and was very impressed with the build and my uncle's sourced components.  He suggested I enter it in some shows as it was so well done.  Not sure I'm ready for a motorcycle show but we'll see.

Running PIG RICH so got a complete set of jets for the carb.  Almost 200 miles of just bopping around on it.  Got a chain guard on it now along with an Air Hawk seat cover.  I tuned the carb as best I could today but it’s still stinky and pipe is full of black tar not soot so time to tear apart the S&S Super E carb.  It’s slow but I’m hoping fine tuning the carb will make it run much better at higher revs.

S&S carb very sensitive to idle mix adjustment, 1/8 turn is a large change.

Idle mix must be set hot (~50 miles), if you set it cold it will blacken the plugs.

I'd start with a 29.5 low speed jet and a 72 main jet.

Do not put drag pipes on it.....

 

Do not transport the bike on the side stand, tie it down upright not leaning on the stand,

Thanks for the input on carb and trailering.  

I drove it a bunch yesterday then went thru settings on S&S website.  Seemed to be somewhat better but still puffing black smoke at idle. Today I pulled the carb down and saw a 29.5 low speed jet and 70 main jet.  I dropped to a 28 and 66 but saw a missing oring in the ejector rod and the bowl gasket was a bit rough.  Also accessing the bowl screws was a PITA.  I had to break open the oil lines to the rocker boxes, loosen up the oil pressure gauge, and remove a plug wire (dual plug conversion) to get the bowl off.  Parts ordered including some sweet extended hex head bowl fasteners, gaskets, o-rings, and a new air filter.  I’ll get it back on the road as soon as I have the parts.

Sometimes it is just easier to pull the carb off.  Kinda sounds like you need to go through the whole thing anyway.  The Super E is a great carb for 1200-1340 CC bikes.  Keep a record of what jets are in it and how it acted with the jets, then start fiddling one at a time.  Only change the idle mixture screw after it is fully warmed up, as noted by bentwrench.  I do mine after like after 20 minutes of riding.   Turn the accelerator pump completely off until you have the mixture right.

Thanks Dr. Hess.  S&S Cycle has a couple of good videos on YouTube for base line settings and jet changes should that not cure the issues.  I've noted the jets that were in place and what changes I've made.  Carb is clean and bike fires easily just really rich.  I rode for quite a while before making adjustments on Saturday.  It did help a bit but not enough.  The 29.5 (mistake-28 jet was installed not 29.5) and 70 jets were pulled and swapped for smaller and the new parts will make future changes easier with less disassembly.  My uncle only did two-lane roads so I doubt he ever dug in to the carb.  I am working on making it run better.  I'm looking for a clean running engine not ultimate performance.  I'm too new of a rider-and the bike is to old of a bike- to have that for a goal!

 

Bentwrench-not sure what you mean by drag pipes.  I'm using the exhaust that my uncle installed-two into one with a muffler.  I've spoken to local H-D techs (grey haired guys with their own Shovelheads) and they have advised a two-into-one system is the way to go.

Drag pipes (on a Sportster):

 

On the S&S Super E, most of the time you are running off the idle mixture screw and the intermediate jet.  The main jet doesn't come on until you are getting pretty far up there in RPM and flow.  Fiddling with the intermediate and idle mixture screw is what you probably need to be doing, but again, with the accelerator pump turned off (screw out.)

Thanks again.  I expect the parts will arrive today and hope to get some time to work on it.  Lots of family activities in the next few days so, sadly, that may not work out.

Was busy end of the week getting ready to go camping in this little beauty!

1963 Airstream Bambi.  16' of polished aluminum glory!

Got home last night and back to work today.  Got to the garage tonight and re-assembled the carb with a 26.5 intermediate and a 66 main jet.  Pulled better across entire rev range on the short trip I took tonight.  I'll get some more miles on it this week and re-run the carb setting procedure.  I'm happier now than before about how it is running.  I also installed a new air filter, extended hex-head carb bowl screws (for faster future carb changes and work) and used Loc-tite on all threaded fasteners when I reassembled it.  Feels good to work on something my uncle took such great care to build and had loved so much!

Make sure to always put blue loctite on the three screws that hold the air cleaner backing plate to the carb.  If one of those screws gets loose, it gets sucked right into the engine.

Thanks!  I saw that when looking around on the Lowbrow Customs site where I ordered the extended bowl screws.  I had the carb bore blocked with a rag when I tore things down and again tonight when I reassembled it.

Mirror pic.  Just noticed my Cougar in the reflection.  Not planned at all.

 

Put on some more miles today and like how it is running with the reduced jets.  Not much acceleration but pulls cleanly through the rev range.  Now to toughen up my butt and back!

Acceleration is all relevant.  A 74" shovel is not that fast of a bike, all thing considered and compared to the bikes of today.  It can be made fast.  Really fast, like wheelies in 3rd gear by rolling on the throttle, but it will cost you.  A lot.  In dollars and reliability, and reliability wasn't that good to start with.
