    Hello again from Serres-Greece

    First thanks a lot for your help with my other problem....everything solved.
    So i decide to apply APmod1 ....i ve made it and know backfire appears on my exhaust and at middle rev the engine bogs..
    I have undo everything as it was or there is any solution with the air screw....?
    Changing jetting is a little bit hard here in Greece.
    Thanks in advance and i apologize for my poor English-Bike is a Honda Crf450r 2005 Cylinder works big bore kit.

    cheers

    the "air screw" on a 4-stroke is actually a fuel screw. you can adjust it but it only affects the pilot circuit. which will be idle and off-idle to 1/4 throttle. if you are having issues 1/2 throttle then you need to look into your needle and main jet.

    Undo the AP mod and see if the problem goes away. If the bike was ok before dont mess with it.
