    426 Big Bore Kit ??

    What about for yz400s?? I have a 98 with a 426 tranny but what's the biggest bore a 400 can handle?

    Yz400 vs yz450

    Yeah that's what I figured but I do drag with some buddy's out on the forestry roads and I just wanna see if there really is that much a difference between the 400 and the 450

    Will the 450 be faster though? Or have more power?

    Yz400 vs yz450

    I have a 1998 yz400f It has full exhaust, rejetted, flywheel weights, and a transmission out of a 426, but I was wondering how it would do against a 2007 yz450f? Like which one would be faster and have more power? I'm looking at getting one but I don't want to spend the money if its slower than my 400.
