I have an 05 CRF450 which I had a full DR. D pipe. I ran the Blue needle with great results. Since I have smashed my pipe and I am back to a Stock bike with only the filter screen removed. My bike is telling me I need to re-jet but I'm not sure what to run. I am in Arizona 1,000 - 2,000 feet and the temps are getting hot 90+. Should I run Red Needle? Which Main Jet? Thanks for the help.
