The transmission no longer shifts with a super-loud clunk. (It still clunks a bit, but it has always done that since I bought it a year and a half ago.)
Glad I could help. One final note. If you have the late model fine pitch metric idle screws then 5 turns out is a fairly normal idle setting. If you have the earlier coarser pitch screws and the screws feel wobbly and unstable being five turns out then you may want to consider enlarging the idle screw orifice to obtain a more normal setting of 2-3 turns out.
