HI-4 Dual-Fire Performance Ignition
Fits 1970 - 1998 and some 1999 Harley-DavidsonŽ big twins with EvolutionŽ engine, (non-fuel inj.) and 1971 - 2002 SportsterŽ models.
That Is what I got, lets see at the point of where i have to set the degrees. and set the tach that is not making sense. as well as i dont have a tach. is there a way around that or do I have to get it into a shop whats the deal?

For most aftermarket ignition modules, setting the static timing is usually sufficient unless you've got a lot of mods in your engine that require a slightly different starting point. (meaning you set the static timing and don't worry about the dynamic timing)
The procedure (which should be outlined in your instructions) goes like this:
1) Bring the front cylinder up to TDC on the COMPRESSION stroke. (the timing mark will show TDC on both the compression and exhaust stroke - it's gotta be TDC on the compression stroke to properly set static timing).
2) Turn on the key, and rotate the module clockwise until the status LED just goes out. That is usually it.
As to the tach wire - if you don't have a tach, wrap the end of the tach lead in tape, and shove it back under the wiring sleeve.
Hope this helps - if not, then ask more specific questions.

Oh dear,I see trouble ahead.

I'm going to suggest that you go find someone a bit more knowledgeable to help you walk through this - as evidenced by the questions you're asking - you really don't have the background knowledge to tackle this by yourself.
Quick answer - pull the plugs, put your thumb over the front cylinder spark plug hole. You'll feel either a strong push, suction, or a weak push.
When you feel suction, followed by the start of a strong push - THAT is the compression stroke. Turn the engine over a few times to get the feel for the different pressures.

I think you can do it, keep the faith. Also, use a pencil in the spark plug hole to determine TDC, when it goes up, stops, then starts down, that's TDC. Then just check your timing mark to be sure. You're only going to be doing this once, right?

I am going to admit, this is going into where my knowledge is lacking, Im a bit out of my comfort zone but Im sure I can work it out besides im an engineering major if i cant work this out man my future is bleak
ok now I know what the compression stroke is, since you said the suck and push (in plane terms). lets see. I got the plug off and shot oil every where xD trying to turn that "wheel" not sure of the correct term. to the tdc but doesnt seem to turn. Im going to keep cracking at it. Ill get it.
