Which CRF cam cahin is the one everyone uses in their 400ex's? I was wondering since I am thinking of switching to it if I go with my 416 kit. Thanks in advance, Steve

? Its from an 02 CRF 450! The XR cam chain is the same as the EX as far as I know. Just go to www.servicehonda.com and get the 02 CRF 450 cam chain, its only like $25

The CRF chain has one extra plate on each link, making it a little more durable. It's a little wider, but it doesn't affect anything. This may or may not be true, but I heard that the CRF chain is made in America by Moog, which is why it's so much cheaper (no import tarrifs).
