I would caution about trying to “dial out” the four stroking if the bike is otherwise running well. Its always safer having a two stroke set slightly richer than lean. I seized my Cyclemaster last year after extended running on a part throttle (and yes it was still four stroking). Even “modern” 2 strokes like my RG500 four stroke like a “good un” on a part throttle.
My Scott certainly four strokes quite a lot and it is too lean if anything!! As said, if it bothers you then just lower the tickover adjuster right out 😀
