HI_DESERT_DDR Posted February 21, 2007 Posted February 21, 2007 Just bought a yoshimura comp series exhaust and I was wondering if anyone knew the recommended jetting for this exhaust on an 04 YFZ450 or if anyone knows a good source to find out? Thanks, Chad Quote

sandcrab74 Posted February 26, 2007 Posted February 26, 2007 This will be your next best friend http://yfztech.com/ well right behind DDR I guess. Also you can list your mods and your alltitude and Im sure a few of us on this board can get you close. Quote
Bound4Dirt Posted February 26, 2007 Posted February 26, 2007 Not sure if Greg comes around here anymore or not. He will chime in if so. He has a 450R Quad. I thought him and Bob put a 140 main in. He has a full pipe. Ask "Barefoot Bob" he might remember. I just watched on the deal. Quote
HI_DESERT_DDR Posted February 26, 2007 Author Posted February 26, 2007 Thanks to all for your info and help hopefully I will have my Pipe on for this weekend in Dumont. Quote
