Sounds like you got the wrong part. I have two models of that protector from EE. One on my 99 250E is flat on the outward surface. The one on my 01 400E has clearence for that rail above the chain.
I just looked at the website (
http://www.enduroeng.com/protection.htm ) and they don't show the exact model. They do have a 'new lower' price though.
