hi am no genius but is your car fuel injected ,if so maybe the injector maybe partly blocked and can cause the miss firing of the cylinder. maybe try some good carby cleaner ,it may help

Yes, this is a very common problem. Often times it is the inverter capacitors that wear down (they look like small batteries with a white stripe and are close to the transformers). If you can get in to the circuit boards, these capacitors are often visibly swollen on the tops; they are normally flat with an embossed X.

If you are going to replace the capacitors, pay very close attention to which way the stripe is; if you reverse this, the capacitor may explode.

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

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 into all the little airways and fittings in the carb. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road. Pay special attention to the noted area. A “very helpful” rating for this answer? Thanks!

it is possible that th eplugs might be fouled but it seems unlikely after only two weeks running-my fzr would foul plugs but it usually takes months not weeks-also the engine would start but run on2 or 3 cyls. I found using one heat range hotter than standard plugs helped,esp. around town you seem to have been fairly methodical on your troubleshooting-if you have fuel and spark the next thing to check is comp. -if the plugs are wet it is likely fuel not oil-when I first bought mine it had sat over winter and would not start -it turned out that the valve clearances had closed up enough that it was low on comp. when ridden frequently it was ok but as soon as the oil had drained off the cyl walls it would not start-squirting oil in the cyls. would get it started but I pulled the cams and set valves to solve problem-starts ok now but I don't use the choke-you could lift the cover and check your valve clearances -it would be a good idea on a bike that you just bought-don't give up -be methodical and check one thing at a time-when you get it going it will be worht it

SOURCE: Defective ignition coils?

You should be able to check for continuity/resistance at the terminals for the coils. If you have no continuity, or very low resistance, you most likely have bad coils. The old Yamahas had very crappy electrical systems. They have a lot of problems with CDI's, coils, and stators/rotors/regulators/rectifiers. You should be able to get continuity through the wires from one end to the other also.
