'02 YZ426 jetting / '03 cam mod

2 posts in this topic

I have a stock '02 426. I am going to be doing the Cam mod and putting on an FMF Q2 silencer. FMF says they recommend starting with stock jetting but I tend to think they just didn't spend very much time testing jetting (based on the great info they give in the instructions).

Any ideas? I have read the jetting FAQ but not a ton of info for '02 with cam mods and a Q2 silencer...

If no one knows about the specific jetting-will someone please tell me if I should change the jetting when I do the cam mod?
