Check compression of cylinders, all should be close the same. Swap spark plugs and check if problem cylinder moved. If bike sits for long periods of time then most likely it will be a plugged carburetor.

SOURCE: What size spark plug do
I don't believe your problem to be with your spark plug. Did you hit anything with your blade before this problem started? If so your problem is with your timing.
You will have to check your shear key. Remove the top cover to your engine and any attachments. Remove your flywheel, and you will see the shear key between the flywheel and the top of the engine crankshaft. If the shear key is even slightly dented replace it . This is what is causing your problem. You will be up and running soon. GOOD LUCK.

Check compression and timing belt. If belt is ok and you have compression, check to see if you have a pulse at the injectors. You use a device called a NOID light (basically a light bulb that plugs into the injector plug. Unplug the injectors one by one and plug the light in then crank the engine. Light should blink on and off if the system is working properly. If not check for a bad crank sensor, blown injector fuse and wiring harness. Hope this helps.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.
