Really...strange what you need to do is see if the bike is running too fat. So...warm her up witha fresh set of NGK! spark plugs. After the bike is warm take it down the street and back. When your on the way back get on the throttle and accelerate then shut er down and coast it into the garage. This will give an acuurate read on the spark plugs at operating temperature and under a load. Pull all the plugs. If they are brown like coffee with cream that means carbs are adjusted correctly. If they are black and wet too rich and if they are white or very light brown too lean. Other problems may be oil soaked plugs from loose top end parts. Maybe valves or guides.

Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? ( not all bikes have a water trap bowl ). Drain all the old gas from the tank. Install an in-line fuel filter. You will need to clean the built up varnish from the evaporated gas out of the carbs.
FOR EACH carb > Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Balance and sync the carbs.
I strongly suggest you to let the shop take care of the carbs. Cleaning can be a nightmare times four and doing the balancing and sync of the carbs sounds easier than it is. If you do the carb work then be sure you have a fire extinguisher at hand. I am serious about that.
Please rate this solution. Thanks!

No one thing controls those items.
The ignition and headlight circuits
each have their own fuses under the seat.
If you have power to both of the coil sets
then the coil for cylinder 3 and 4
might be faulty.
Lights may just have a blown fuse.
You have more than one problem
going on there.
