interesting... I actually find the phong and MQ bezels a hair too wide for gen inserts.. so my guess is that the OD of the Yuki's are slightly wide...
if you have a caliper, measure the OD.. It should be around 36.55mm. If its 37.00+, then it will require some trimming.
Alternatively, you could slighlty bend the inside of the insert higher, so that the insert becomes more "conical". As a result, the OD will become slightly narrower and might fit then. If that doesnt work, fall back to Option A and trim it slightly... you might have to trim both the OD as well as the bottom to top thickness but sliding it flat on some 800-1200 grit paper.
Rather you mod the rep insert than one of your bezels.
