i put a dr750 in my 88 mojave ...yes a kawi....so it shouldnt be all that hard... thats why you use a dr750...55hp 70ft.lbs torque..stock...my mojave can pass a 400 ex with mods in second gear...never measured top speed yet but i had it doin 105 mph

but how would a street bike engine ( Ninja ) do on trails or such...they have to be all top - end im guessing...i have only heard of street bike engines in quads for the dunes...but that dr750 engine sounds like a BEAST...

my friend has a 400ex with a pipe....uni filter...cam....jetted..and the only time he can stay with me is off the line for 100' or so...by the time hes wide open i'm only coming out of second gear....his stock acura integra cant catch me either until the tires i have on the back get so outta shape they look like they'll come off
