I am not a expert on the subject, but I know that there's one ignition coil for the outer (#1, #4) spark plugs, and another for the inner (#2, #3) spark plugs. If you bought new ones and tested them without them firing I would suspect the ignition coil that fires the inner spark plugs is bad. ..Try changing the plug wires i had the same problem and the plug wires went bad after using the horn (it shorted out) , i found that out after removing everything on the bike and testing it and yes i was mad but relieved it was just the plug wires , good luck

This is a problem with this engine. Read the link below.
One at a time, checking your gap on each plug and putting never-seize on the threads. Make sure you change the plugs on a cold engine, there is a problem with them breaking off inside the block.

India is not the problem, it is ear plugs

check and regap your plugs and make sure all plug wires were installed in the same place. You put the wires back on the wrong plugs.
I have a kx 250 dirt bike that keeps fouling plugs on start up. I rejetted it but that still didn't solve the problem. What could be the Problem?
Spark plugs need to be changed. had the same problem and it disappeared when I replaced the plugs.
The only time I've seen cracked spark plugs was putting them in or taking them out with the socket not perfectly straight.
Usually this means you need rings
plugs or vacuum. 65;
