Will a 2005 400EX engine work on my 2002 400EX frame?


Recommended Posts

I'm going to say that you may have to do some very minor modifications. I'm sure the engine would fit fine as far as mounts, I'm not sure if all the wiring coneectors will be the same. Just curious, how do you put a 400EX in reverse? Is it with the shift lever or is it on the bars? I've never been on a 400 w/ reverse.
