I've been getting a YZ85 fixed up for my son and I've got some jetting questions. When wicking the throttle from 1/4
throttlw or idle it falls on its face and dies. If you roll it on it pulls hard. It idles nice and has decent throttle response, just a mid-range bog.
Main is 138 and pilot is 38. Clip is on the richest notch which did help it but not completely. Am I chasing a pilot or main issue?

That said it's usually a pilot/air screw issue. You can also try running a slide from a KX85 (3.0) which is slightly leaner. I doubt I can find my YZ85 tuning specs as it's been awhile but I do remember tuning air screw every ride..............
