1994 CR125 Jetting

[bigsmoothrock]

I have a 1994 Cr 125. I ordered a FMF Fatty and the Powercore 2 Silencer. Can anyone tell me if I have to change the jetting on my bike. If I do can you tell me what jetting changes you have to make.

Thanks, Chris

I didn't have to change mine when I got a fatty with a powerore silencer. I was runnning a stock pipe and silencer before. I live at sealevel. slow 58. main 168. needle 1470 clip in fourth slot from top. But I'm not a real expert at jetting, but it ran well as far as I could tell.

Do you really want to rely on someone that is 1000+ miles away to jet your bike for you? You should check your jetting every time you ride with new parts/different temperatures. Do a search, It will tell you how.

I was just telling him that I did't need to change my jetting. What is wrong with that?
