you can rest the warning by unhooking the pos.+ batt. cable but it should be change in the programming so it does return. Mine does the same and keeps giving what HD calls a historic code miss fire on 1 coil. Some times it can be something as simple as aftermarket plug wires.

If I understand correctly, Your bike has points in it now and you want to go to electronic ignition. If that's what you want to do, I would suggest that you go with one of the aftermarket ignition units. They're more versatile, costs less, and easier to install.
There are two types available. Your bike has a mechanical timing advance unit behind the points breaker plate. One type of electronic unit eliminates this mechanical part and makes the system truly maintenance free while the other type retains the mechanical advance unit and cost less. A prime example is Crane Cam's HI-1 unit that retains the mechanical advance and their HI-4 unit that eliminates it. Most bikes made after 1984 do not have the mechanical advance units. Since your bike does not have any of the original components left on it, I would suggest that you get one of the units that goes in the "nose cone" of the engine. It simply replaces the everything in there if you get the unit that does not use the mechanical advance. The Mechanical advance units are prone to wear and since no one ever services them, I'd suggest getting rid of it. You'll have to purchase a "timing cup" from Harley, costs about $20, a lot less than $100 bucks for needle bearing mechanical advance unit. Get the shorter screw that goes with it as well.
All you have to have with either unit is a "hot" wire going to the coil. The coil must have a primary resistance of somewhere around 3-4 ohms where a points type coil has a primary resistance of 4-6 ohms. To determine the resistance of your coil use a Digital Volt Ohm Meter and measure the resistance between the two small terminals on the coil. To wire the ignition units is usually just a two or three wire hookup that is very simple. They all come with wiring instructions.
Now, the next thing is whether you wish to stick with "dual fire" ignition or go to "single fire" ignition. Dual fire is the system that almost all Harley's come equipped with from the factory. In this type of system, both spark plugs fire when the pistons are top dead center. Since one piston is on the exhaust stroke, that spark is of no consequence and therefore is considered a 'wasted spark". In a "single fire" system, the spark plugs fire independently when each piston comes to TDC on the compression stroke. It requires either two coils or a "two in one" type coil. This added coil increases the cost of the system and to be honest with you, I cannot tell a difference between the two systems. With that in mind, I opt to go with the less expensive and simplier "dual fire" system.

Ok, this will get you started. Installing an electronic ignition system in an older Harley is easy to do. The difficult part is deciding which one to go with. Once you do that, no problem. If you have anymore questions, drop me a line at email@example.com .
To see how to hook up one of the units, go to their website and look for a "Technical" page. Go to that page and look for "installation Instructions". Print them out and it'll tell you everything you need to know. If not, I've got some different types of systems installation instructions that I can scan and send to you.

Well, this depends on the degree of the hesitation. An S&S carb will have a small hesitation no matter how well you tune it. On those, I suggest that you roll the throttle on rather than snap the throttle wide open. I won't get technical as to why this happens.
On your SE carb, it's designed more like the CV carb that came on your bike from the factory. Since it's a Mikuni carb, there are usually an infinate number of variables that you can change on the carb. If you can find a supplier of the parts that will fit the carb, you can change the accelerator pump nozzle to a smaller nozzle. This will allow the same amount of fuel to be delivered to the carb when you open the throttle but over a slightly longer period of time. Or, you could go the other way. A larger nozzle delivering the pump shot over a shorter period of time. Fine tuning is an art and it can get time consuming and expensive buying all the variable parts.
My suggestion would be to roll the throttle open rather than snap it open if the hesitation is minor. In the case of a "fall on your face" hesitation, you'll have to find out what the problem with the carb is. I'd suggest diaabling the accelerator pump and changing the slow jet richer or leaner until you get it to where the engine idles like it should and revs cleanly. Then, put the accelerator pump back in but don't adjust it too rich, too large a pump shot.
A word of advice. You can tune a carb for the rest of your life trying for perfection and never achieve it. Get the carb as close as you can get and ride the bike. Do not become a "rolling mechanic". That's a person that instead of enjoying his ride, he's working on his bike in his head the whole time he's on it. Although I work on Harleys all the time, when I ride mine, I disregard every noise and thing that it does unless it just quits. If it breaks, I'll fix it when I get it home. Until then, I'm enjoying my ride. The newest bike I own is a '94 FXDWG and I love that bike.

if the bike is tuned properly with the s&s carb,it will not hesitate.i have a 2002 fxdwg 96 incher with a s&s g and I can snap my throttle all day long. so stop putting out the wrong message.
