Is the topend on the 400ex and 350x the same? I no the 400 has more cc's but are they interchangble and how does the 400 get more ccd bore stoke? And are the bottom ends similar? the 350 is a 6 speed I was wondering if you could put a 350x bottom end on a 400ex with the 400 topend has anyone dont this and would it be worth it?
Nope Won't work.
The 350x motor is closer to the 300exs than the 400exs.

they are just identical looking then?
I had a 350x for years and now have a 400ex, they look nothing alike. the 350x/250x/300ex family shared similar designs with changes made over the years. while the 400ex engine is based off the xr400 dirtbike. totally different.
is there a big differnce in speed and power between the 400 and 350? i thaught i read somewhere that they were pretty close to the same and the 300ex and the 250x are real close.
