yz426 and 400ex?

[EXDUNER127]

How much do you guys think it would cost to put a yz426 motor in a 400ex frame, i know it is being done but how much and what mods would you need for it to fit. And with that and new piston cam and motor work?
How would it perform compared to the new 450R coming out in performance. cause i like my bike and dont want to get rid of it.

it would cost you about this much...i have the motor, carb, wiring, oil tank, exhaust, radiator, and a 400ex frame/subframe that was converted by east coast atv...all for $3200...take that and subtract the amount you could get for all your stuff and that is what it would cost...
