1984 FXSB with S&S Super E, Ultima programable ignition and dual plug heads. Intake seals are less than a year old.

Super E has .032 pilot, .72 main and mixture at 1.5 turns.

Engine starts right up warm and runs great thru the entire rev range. Cold start it is cranky. With the enrichener up it will crank and cough (electric starting). I find I have to give it several twists of throttle (like over 7 twists) to get it to fire. Once it does fire I have to wait quite a bit (few minutes) before I can push down completely on the enrichener lever otherwise it will stall. No issues if I shut the bike off for several hours... pull the enrichener up and it fires right up. It's when it sits for over a day that I find it needs several pumps to get it going.

Almost seems like the bowl goes dry. No fuel dumping out of the overflow when it sits.

Nature of the beast?

 

Pilots should .031", drop the main to 70 unless It's cammed up pretty good. Two things I'll suggest is maybe pull the petcock and clean the screen and start looking at what setting you have on that ignition unit. Could have too aggressive a curve running.

 

The pingel screen is good and clean as I had to remove it a few weeks ago to get the tank repaired.

Will try those smaller jets (it does seem a tad fat on the jetting). I have the timing retarded a bit due to the dual plug heads (timing mark on the left edge of the timing hole). I will check what curve it is on.... no pinging issues..

 

With the Pingel try running it in the reserve position, see how it acts. Had a couple of those get a bit goofy feeding.

 

Will do

 

Check the accelerator pump adjustment and try backing it out a half turn. It might start easier but it still will need to warm up some.
Mine won’t idle with the choke off for a minute or two but I can go down the road in less time. I just keep the throttle on a little at the stop sign.

 

Take air cleaner off, are you sure the accelerator pump is squirting into the carb when cold? 7 twists sounds like a lot, I would have fuel on the ground if I did that.

 

Sounds like the timing while cranking is too slow.

 

If the ignition is a not a K series then its only electric start - as the k series meaning kick start is hitting the sparkplug at first movement not after the engine is spinning on the starter

 

Hey John it is definitely not a kicker friendly ignition... out of the box it is 3 dead revs but I did re-program it to 0 dead revs..... I don't even attempt cold starts with the kicker.... strictly e-start... it does however fire up 1-2 kicks with the engine hot.

With the Tech Cycle starter and Anti Gravity battery it spins over real nicely.... just requires a lot of twists of throttle to get it primed (will be trying all suggestions here this weekend).
