So I have a brand new exhaust and jetting kit. I got the FMF megabomb header, Factory 4.1 Ti slip on, and the FMF power-up jet kit. I have the 2005 YZ450F, wondering if anyone with this same setup has found a happy spot for jetting and needle settings at around 3000'. A general idea of where you set your idle screw would be helpful too, but I have the zip ty on the fly adjustable one, so whateva! Thanks for the help my fellow riders.

I have always had great luck with the JD jetting kit for the 4xx bikes. Jet it per instructions, adjust the fuel screw to tune out the bog and ride.
