KZ 750 wont fire on cylinders 1 and 3.

I have spark and fuel on #1 cylinder tho I dont know if it is getting past the carberator. Just changed spark plugs. carbs look like a nightmare to take off and clean.

Be more certain and clear on symptoms , by yoir title ill say ita either a coil, or point side or pick up on one side went bad or wiring between. Im drunk as ten mofos but check signal from points or pickup, if nothing, you know if you get signal from the ignition source "points or pickup" , check continuity on the wires, it thats sound, its a coil.if this dont make sense sell me your bike for ten dollars lol. Best of luck!

First off welcome to the forum.

I'll second more info and you can add year and model to your profile. Is the spark weak or blue. Old bikes with factory coils do cause problems.
Do you have battery voltage at the coil? I know I lost alot of voltage between battery and coil before I got the connections cleaned up. Mine was about 10volts at the coil and I had weak sparks.
I'm sure others will be along to help.
