xr400/400ex

[250xsupertrapp]

is the 400ex/xr400 motor the same thing

Basically, but there are some differences. The xr has a smaller clutch, its kick start, different transmission gears, narrower crank due to no electric start, etc. But all the parts are interchangeable unless you have a '05 and up ex motor.
