    top end will drop quite a bit unless you put a 14 tooth sproket on the front which i would do if goin to 18's


    you'll get lot more acceleration with 18's though, have to go threw the gears more though

    I had my 300ex with an fmf megajunk and a K&N, and I clocked it at 63. I haven't cloked the 330 yet but I can't wait to see what this will hit. I am hoping for 75 . I think it will do it because I can outrun a piped 400ex, and I hear that most piped 400's hit 73-75.
