    Prop Issues?

    Allright everybody i need some help understanding some performance issues with my Fzr. Recently i did the intake manifold upgrade, power filter kit, intake grate and changed out the prop from stock to a skat track 12/20. I took it out for some test runs and could barely break 67mph. prior to this when it was stock my average gps speed was 67.4 to 68.6 The only thing that i can figure to be the problem is the prop? If anybody has any suggestions on what i need to do please let me know. If it is the prop do i need to have it pitched or just get another new one all together?

    RPM'S are right were they need to be. By any chance is the grate hanging low were it would create drag.

    I did notice that it is hanging an eighth of an inch lower toward the back end, is this normal? I actually plan on heading to the water in the next hour and swapping back to the stock grate to test and see what changes i get, if any?

    +1. my first thought was that is a low pitch for his setup.he probably has some great hookup and acceloration. but, his top end will suffer.

    I do have much better acceleration even improved mid. So do I need to run a 13/22? I just went and did a water test i put the stock grate back on and gained a mile.
