TZR vs DT reed valve

[Feca126]

Hi all, can somebody know the differences between the tzr125 and dt125 reed valve?
On boyesen website there are two types of valves: Boyesen 715 for tzr and Boyesen 666 for dt.

Looks like one comes with the stopper plates and the other reuses the original ones

The description says fits 4dl, 4dl ran bigger carb and they all ran different inleta. Potentially these won't fit DTR cages.
