Problem getting my 1975 KZ400s to start after doing a whole bunch of work to it

So I have a 1975 KZ400 kick only motorcycle that ran pretty damn good when I got it a couple years back. I had a buddy that wanted me to build it into a hard tail and just make it simplified. I had tore it all apart other than the engine, made it hard tail and as it set for a couple of years I lost some of the original wiring and whatnot but I just made a bare bones simple wiring harness for a new headlight, brake light, key switch, new Mike's Reg Rec combo, new wires and boots, new spark plugs, 3 ohm magna coils, and electronic dual fire ignition, and two new Mikuni VM 30's (that I bought from Summit Racing last year) but haven't done any changing of the needles or anything of that nature because I am not that proficient of them. I have timed it and every time I send it around the indicator light lights up just past the f mark, I have spark because I checked it with a inline plug tool that lights up as I try to kick the Kickstarter. I'm not that great with these older Japanese bikes with the multi-carberation but when I try to kick start it it just seems like I am not getting any rumble of any sort if that makes sense. I just really need some help because I don't have transportation and the little bit of money I do did have I have put into this being mostly all new parts and I don't have anybody local that can help me! Please someone give me some info or what to do or ask questions maybe I can explain better what it's doing with somebody's questions! Thank you just would really love to get this thing started

Any motor needs 4 things to start, you need to identify what you are missing (what ignition system are you using ?)

• Air
• Fuel
• Compression
• Spark (at the right time)

Spray some starting fluid into the carbs. Then try to start it.
What do your plugs look like after trying to start the bike?

It is Spring. Officially.

They are clean as hell

I'm using a dual fire ignition that was meant for a Harley. It's the same one I watched a guy on YouTube used on his kz400 and it worked great for him
