I thought the YFZ was a mx bike not a duner..I may be wrong..
Put a pipe on a yfz a dale and a shee and drag that shee will win.
Also, just having a "big bore" shee isn't gonna make hardly any power if the engin isn't built and ported right...
I would love to see ANY other quad mod for mod beat a passion racing 370 +4 stroker with 34 pwk's and shearers, cpi"s, or rocket inframe pipes...
Just to let every 1 know im not trying to bash other quads, im just saying that mod for mod there realy isn't another quad that will beat a shee AS LONG AS the rider on the shee is good, I would love to own a yfz, I realy like them so im not saying anything against them, they are fast but I still think a shee could take it..
