3 of the plugs looked very nice .None of them were white. They had hardly any residue. One plug was wet. Looked like it had not been firing.  Air filter is in the airbox.

I took it out today to see what it would do. It hits 80mph right about 7000 rpm. It then starts sputtering like it is starving for fuel. I can hit 8000 rpm in 1st 2nd  3rd etc  but not in high gear. I guess that might be because you do not have to open up the throttle all the way in the lower gears. I will pull the fuel screen and look at it and check the fuel hose and make sure that it is not kinked and cutting down the flow.
