I'm not sure which circlip you need but try an internet search using the OEM parts #
such as 9344025020

Edit: wrong part # that one you want may be hard to find
is there a Yamaha dealer you can contact near you
They can search around to other dealers and maybe / just maybe one of them will have one?
