As with all things, go back to the basics: 3 things needed for internal combustion engines. Fuel, Ignition and Air (Compression). Given as you have a 1995, a carbureted V-Twin...the easiest thing to check first, if starter is turning engine easily (not labored)...and battery operation reasonably up to snuff...
1.) Fuel, turn petcock past to prime/reserve. Retry, if not, pull air cleaner cover and look into throat, if you have accelerator pump rolling on the throttle should see and smell strong squirt of fuel.
2.) Ignition, pull plugs, do they look reasonably clean, not fouled?...stuff rag in open port, replace boot contact firmly with tight plug nipple, and ground shell to the head (checking for spark that jumps gap...open air should be easy to check for strong spark from both...
3.) Compression check next...of course by the time your read this part you are already thinking, I need a service manual or check should check the HDTimeline Self Help section to find more troubleshooting tips...
Sorry, very tired now, the point being that sometimes " Won't start" will cause some to stray from the basics, especially if we do not know what the conditions were before during and after the first failure occurred. Sometimes problems can be "self inflicted", and often the problems are basic, rather than complex...
