I recently purchased a used '99 CR 125 and was told that I may need to adjust the jetting and or needle settings to accomadate the pro circuit pipe/silencer and a v-force reed assembly that I just installed. Any chance someone could point me in the right direction ?? The previous owner has already changed the jetting to accomadate "woods" riding, but I plan to ride more motorcross style tracks. I guess my point is that I am not certain of what the current jetting is or if it is even the original needle. Thank You for any input ...

NO thoughts or opinions ???

The best way is to jet your bike for the mods as no-one elses jetting will be exact for you,eric goors web site has a good tuning guide for jetting.
