2005 yfz450 jetting help!!!
Hi, I have a 2005 yfz 450 about to install fmf q4 with powerbomb pipe plus k&n filter. I was wondering if anyone had any idea on what jets to use. Air filter lid is off. I'm about 600ft above sea level. I'm from Chicago so Temperature is always changing. If anyone could help that would be awesome. Thanks.
