    Reviews

    Street Performance Big Bore Stage IV Kit - 103 Cubic Inches is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Top Performance Limited This system works very well and out performed the advertised stats and over 5000 ft elevation. The bike keeps building power after 3500 rpm and over 5000 rpm. I love the upgrade and now looking for something similar for my wife's trike. My MPG is going to be higher too. I did the stage IV with an air cleaner and the SE high flow exhaust. AWESOME MACHINE!

    Q & A

    do you i have to change air cleaner and exhaust on a 2016 flhtk to have this kit installed

    Asked by: Carnivore

    Can this kit be installed on a 2007 FXSTCI with a 96CI Fuel Injected engine?

    I've seen Stage I and Stage II kits that allow a 96CI engine to be taken up to 103CI. Will this Stage IV kit work on my 2007 FXSTCI engine?
    Asked by: Adidas57
    Hi Adidas57, No, the Screamin' Eagle Street Performance Big Bore Stage IV will not work for your 2007 FXSTCI. Please see an authorized H-D for assistance. Thanks!

    Do the heads for this kit come pre-drilled for compression releases?
