    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!
