Ok I need help because I’m about to give up. I have a 1986 Kawasaki 454 Ltd and I bought it not running. So far I have replaced the starter, cleaned the carbs, adjusted the valve clearance, checked the engine timing. All the bike will do is turn over and sometimes backfire. I’m getting a good spark and I’m not 100% sure but I believe I’m getting fuel. Also the only time it will back fire is with starter fluid. Where should I look next? Because I’m about to give up.

Hmm,
Battery - hook up a car battery if possible in case the bike battery is just under cranking amps.
Spark - new plugs? Are you sure the igniter polarity is correct? CDI could be faulty as well.
Fuel - are you running a temp line or using the tank?
Carbs - did you rebuild cleaning out all the jet holes and passages? Checked the floats and choke direction?
Air - the 454 is sensitive to air intake changes you'll need the airbox & filters fitted as stock. Does it have the emissions kit?
Lockouts - there's a few lockout switches in the electrics that would prevent starting. Clutch, neutral, side stand and kill IIRC.
Starter - could the starter clutch be faulty? If you take the generator cover off you can observe the clutch and crankshaft.

Are the coils wired correct? There is a left and right, positive and negative.

So I’m getting spark and my coils are connected correctly. I just bought a ultrasonic cleaner and I’m going to clean the carbs once more. I’ve got ok compression 120 psi on both cylinders, but it hasn’t ran in 10+ years. It does have the emission crap. Could that effect it starting?

While you have the carbs apart and you haven't already checked the diaphragms, now is a good time to do it.
Pull on them, but not too hard, and check for pinholes. Check the float heights. AND make sure the air box is in place with no extra air coming in, once you get it all back together.
Don't give up, you got a great bike there. Set back a couple days and relax, then go back to it. Mine gave me fit but now I have very happy. Took me a year to get it on the road again. Widow of the previous owner was very happy when I showed her is was running again.

the diaphragms are good. ok I have put the carbs back on and now I'm not getting gas to the cylinder. I crank the engine over and then I pull the plugs and they are dry. would this be a float problem? I set them to 17mm dry I didn't check them wet. I've honest never had this much trouble getting a motorcycle running. so far I have replaced the air filters, cleaned cards, checked timing, adjusted valves, cleaned all connection, checked compression, got new tires, replaced the front caliper, and got new brake pads.

I had a similar issue after I pulled the carbs and cleaned them up. I had to remove the carbs again and once or twice more, I'm not a mechanic so I had to learn as I went.
Are you getting fuel from the tank to the carb? Fuel line not blocked to the carb "T" that leads to both carbs. If you are,is it making it to the float needle? Do the floats rise and fall properly? There are several videos on setting the float height, I used the flat surface and a small level to set mine. But, do what you are comfortable with. Oh yeah, lots of carb cleaner in all the holes. Explore the internet for CV carb cleaning and rebuilding.
