It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...

Probably a gas delivery problem to the carbs. Check the lines and check for a filter in the line or at the carbs. Something is stopped up and it can't get enough gas to go any rpms.

Every component plays a part in the ignition system. Check the wiring as you go. Start at one end and move forward. You have done a lot of work so far. so you should be close. If the igniter is fine and the other components too. Then it would narrow it down to an electrical problem or no signal/pulse to the coil. See if the coil is receiving that pulse. you can use a test light for this test. Pos. will be power and NEG. will be the pulse. With light on the NEG. crank the engine over and see if it flashes. Let me know how its going.

The voltage on the coils is present except at the instant of firing. The interruption of the voltage is what causes the coil to fire. The cdi box is what causes the voltage interruption.
The interruption is very hard to detect. You are not the first to be stymied by that box. If you have access to an oscilloscope, I think you can see the pulse if it occurs.

Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.
If that doesn't do it, check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.
