2002 Honda400ex jetting question
I have a 2002 honda 400ex, it has an fmf powerbomb header,fmf titanium 4 silencer, and a K&N air filter. What jets should i use? I live in Pennsylvania and i want to set it up so it runs the same all year round without changing the jets again temperatures range from 20's-90's. What jet sizes should I use?
