Jetting recommendations?


I've got an '07 XR650L and I'm planning on doing Dave's carb mods, UNI air filter and FMF Q2 exhaust and I am still not exactly sure what jets I should be running.

Right now I'm planning to go 55/160 (keihin #'s), does this sound about right?



P.S. Sorry if this topic has already been beaten to death, I couldn't find any threads detailing this same setup so just wanted to double check.

That should be perfect for 500ft elevation and under.Even with stock exhaust if havent changed it yet.
