Jetting for Big Gun EVO R on 05 CRF450R

Recommended Posts

I am getting a the Big Gun EVO R pipe for my 05 450R. I was wondering if anyone has used this pipe and what results they had with it. Did anyone need to re-jet? I am assuming that I will have to, but the website for Big Gun says no jetting required. I guess I will find out when I put it on, but any help is appreciated.

More than likely, you'll need to go leaner. Post in the jetting forum and burned will give you an excellent starting point. Make sure that you list your average temperature, elevation and list of modifications so he has the necessary info the first time. :banghead:
