[QUOTE="nbolls, post: 206561, member: 3988"] So I want to put an FMF Turbine Core 2 (Item# 020361) and FMF Fatty 2-stroke pipe (Item# 024053) on my 1999 YZ250. Previously it had a Pro Circuit Nature Friendly S.A. Silencer (Item# SY99250-SA) and stock header pipes. I am 366 feet above sea level currently. I believe the jetting is stock, but I'm not sure. All I know is that it ran great with whatever it had on before with the Pro Circuit. Will I need to rejet? If I do need to, can someone link me a kit that will work? Thanks [/QUOTE]
