The good news is that your headers don't have any O2 sensors. The Harley Delphi systems didn't use those back then. You could go with something simple like Fuel Moto's load based add-on tuner, which they'll pre-load a map for your stage one and slip ons. You're not looking at very much outlay of $$$, maybe ~$200. They're easy to install. If you can change your own oil, you can put one of these on your bike. I'd bet you could find one of the older Screamin Eagle Race Fueler's on ebay for around $100. You wouldhave to adjust it yourself, but again, it's very easy to do, all you need is a screwdriver. No computer, no maps to download. The downside is if you decide to further mod the engine (i.e. cams, big bore kit...), as these little gadgets will only add fuel, nothing else.
Since you don't have O2 sensors, the auto-tuners won't do any good for you, unless you have 18mm bungs welded into the right spot on your headers to accomodate the wide band O2 sensors (one per cylinder), or you buy an exhaust system that already has them in place. The auto tuners use the feedback from the sensors, along with the MAP sensor, Ion Sensor, et al, to develop fuel/timing map corrections.
I'd say get a load based fueler.....
No job is so easy that it can not be done wrong
