03 R6, lose power at 10, 000 rpm?

I got a new battery to fix most of my problems but I cant seem to figure out why im losing power top end full throttle. It spudders like its being robbed of gas or something. It idles fine and rides fine before 10, 000 rpm. Disconnected my power commander had the same issue. Im thinking it might be my spark plugs. I just dont know how offen you have to change them on a motorcycle. I changed them over a year and half ago. Hope maybe someone can give some ideas on what it could be.

Your spark plugs are fine

It could be a coil going bad, test them as per your service manual and see what they say.

How's your air filter look?

I would but my coils were changed out last year when I changed my plugs. The year I have had a recall on the coils so I did that already:/ and I have a k&n air filter but I havent cleaned it in about a year. Ill check that out and see how that goes. But I just dont see that being the issue. I heard the 03' has a issue with the fuel pump but im not completely sure.
