Motor Life?

I was just wondering what the life expectancy is on the 400ex motor. I was also wondering if there are any parts that should be replaced after a while(ie bearings, timing chain etc..). I know these motors are extremely durable and have a long life but i dont really know the details. Thanks.

My brother has two Honda 250x Four Strokes with original motor, one is an 89, the other a 91. Both still run excellent, and he thinks you are supposed to change the oil only twice a year!

Look in the Powertrain Forum and there is a thread on "motor life" in there with more replys than this one.
