I emailed eddie sanders racing and enquired about a big bore for the cr like they do for the yz now. I mainly want more of a big bore power for the dunes not ao much hp more of a torque thing I also love the ergos of my 03. So the response ESR sent was we will be making a kit for the 1992-2001 as well as a kit for the 2002-2007. I think its pretty awesome another company is making parts for our discontinued bikes. Thought I would share in my excitement.
