Which is faster?????
#2
?
i would think the 450 engine would be faster...but why in a 400ex frame? i wouldnt screw around and put one of these engines in a 400ex frame unless i got it real REAL CHEAP...otherwise it may defeat the purpose. you know yamaha and honda already makes 450 quads - you dont have to make your own anymore!

It all depends on tuning. I know a guy with a crf in a 250r frame who can wipe out all but one yfz in the area. Stock, the yfz will probably not hold up to a bike engine when properly tuned, even without any performance mods on either.
