First,
1.  your first set of plugs could be bad due to age
2.  Your second set of plugs could just be bad period (not unheard of to get bad plugs new out of box)
3.  Check your air filter...if something isn't right it might be blocking air into the intake which might cause the bike to run rich.  If running a K&N is it over oiled?
4.  What pipes are you running?  And have you check your exhaust gaskets
5.  Try the battery trick just to be sure.
6.  Have you checked your O2 sensor?  They do go out ocassionally.  There are checks for them online and if I recall all you'd need to do is disconnect it from under the seat and use a standard voltage meter to check the resistance.
7.  Double check your wires under the tank.  Its fairly easy to pinch and damage those wires as well as the little hose under there.
8.  Check for damaged wires at or near your ECU under the seat.  Unlikely but it can happen.

Last, and this is just a remote possiblity...look inside the bottom of your air box...is it thick (dripping thick) with oil?  if anything more than a film of oil is in there you could be pushing oil out the Crank case vent at the top of the rear cylinder and into the intake.  Normal amounts aren't a big deal but if you had bad rings, it could push a ton of oil out and gum up your carbs.  Simple check is to check if your oil is low and double check the airbox when you change the filter.

Aight  . I went checked all my connections. Every thing is good . Took each plug out and checked to make sure they were fireing.  Going to change them monday when shop opens. Hopefully it is just the plugs. I took my filter out checked to make sure it wasnt moved or nothing had got caught up n it. ( Little over 200 miles on it.  I am now on the V&H 2n2 pipes and i used . Brand new exhaust gaskets. I just done the battery reset. Took the negative cable off for little over a minute. I am going to check the ohms on my 02 sensor. Dont know what it should be at far as specs. I checked the wires up and down . I didnt see any frays or cuts nor nicks.  I do have a little oil in the box. But it is like a light film of oil.  I am hoping that it is the spark plugs.   Could just one spark plug be doing that ?
