06 YFZ 450 jetting
I have the job of rejetting my friends new 450 after we install his new exhaust(Dr D) when it arrives They tell us just to put a 172 main jet in and that will do. Does that sound right?. We have no lid,K+N and outerwares. I would think the GYTR kit with needle etc would be needed.
