    I 1/4 my 02 Busa. All summer it ran well through the RPM's, all the way to the rev limiter if you goofed. Now it won't pull through 10,000 rpm. Not sure what the problem is. I'm thinking injectors, fuel filter, or fuel pump. It idles and runs fine. Just drops off in high RPM's. Any suggestions would help.....

    You both are very correct! Very strange though. The filter had a few part particles attached to it, nothing major, but basically it had a film over it that really couldn't be seen. Tried to draw air through it, and there was resistance. I was surprised that there isn't any filter material inside of the filter. The mesh of the filter is the actual filter....Hit it with some carb cleaner, let it sit, and then blew it off inside and out. Checked the resistance again, and smooth as silk. Put it back together and it ran all the way through the r’s like it should. Thanks…..
