BUJIAS BUJIAS GSX 600 F KATANA

I have a GSX 600 F katana, burns the spark plug of the first cylinder, many things have already been done and we do not reach the problem.
Can anyone help me diagnose the problem?

What do you mean that it burns the spark plugs, I ask you why it has happened to me that when we call burning the spark plugs we talk about the competition or petemcious vehicles and the spark plug pole when we take them out not this and the slab is broken, if you refer to the same is a lot of temperature to cloths revolutions.

I mean that with the new spark plugs, the motorcycle funeate well and the few kilometers turns off the cylidro #1 and the spark plug does not use more (stop throwing spark) and changing the spark plug again and the same thing happens to the few ckilometers.
