'13 XR 650L Jetting Question

Recommended Posts

Does anyone have advice on what to start off with for jets on a '13 XR 650L with UNI filter, FMF Powercore pipe, de smogged, de snorkeled, and Dave's Mods done to stock carb?

Thanks

I have an 08' with fmf q4. I havent drilled out the slide, but all other mods the same. I run a 158 / 55 . Seems to do pretty well.

I went one richer than stock jets and it worked. You may want to try 2 steps richer than stock on the main jet. Did you shave the air screw? You should be able to adjust for the idle with the air screw and one step richer.
