 2005 YZ125 Jetting Does anyone out there have an 05 YZ125. What jetting setup are you running and with what mods? I am putting an FMF SST pipe with shorty silencer on mine and I am looking for a good place to start my jetting. Thanks.  |

| Re: 2005 YZ125 Jetting yeah, i have a 05....the jetting from the factory was way jacked...rich on top,,,lean in the mid, and rich as hell down on the bottom...i have bills pipe on order with an fmf titanium and v-force 3... the jetting is get'n close...i use vp u2 and castrol 747 so my numbers are going to be different than yours. i would start at 1 down on top, keep the pin the same, and a 35 to 30 on the bottom @2 turns out. after i get all the parts to try i'm going to run them all on the dyno and C what combo is the best! |
