400EX Timing chain modification

[Chuck_Norris]

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.
