Title: 400EX Timing chain modification Post by: Chuck_Norris on March 28, 2008, 12:06:53 AM (http://i5.photobucket.com/albums/y162/Chuck_Norris/DSCF0688_edited.jpg)
This is a direct swap. on the left side is the CRF450 timing chain on the right is the Stock 400EX, The 400EX chain has a history of stretching over time or under certain circumstances. The use of the CRF450 chain eliminates that. I am installing it in my Project 400ex.
