    Get a pipe , filter , jet it , bore it to a 416 with an xr cam and higher gearing and you might be able to pull 75-77.

    Theres a huge diffrence between 2-strokes and 4-strokes.
    Banshees repond alot better to pipes then a 400ex or many other 4 -strokes would.

    yes im very aware of that i hate to say i dont believe you cause you may be very correct but from what ive read and understand to be true all those mods are supposed to and 15% more power so 15% of 65 is about 9.75 mph so that should put us between 70-75 no problem right?

    i just read the review of the K&N jet kit and air filter and those alone are supposed to give a 15% increase not to mention the pipe so theres no way that it would hit 70-75 mph **** if the k&n only gave half of that coupled with the pipe thats a solid 75 on pavement no problem!
