Showa 43mm fork service

[thegunner76]

Hi, folks!

Im doing a service on my Showa 43mm fork that sits on a ’04 Monster S4R.
My problem is that I cant find the o-ring for the top cap. The top cap, or “plug assy” as its called, is only sold complete (nr 34920141A).



I understand this is the same fork used on the Suzuki Gsxr 750/ 1000, but I haven’t found o-rings listed for those either.

The easy way out is to ignore it of course, and I doesn’t seem really necessary to replace them either, but still… Im here now and Im guessing the forks didn’t have any service at all yet (every 30K km and the bike has about 35K). So why not do it properly, right?
Does anyone know which o-rings to choose?

I'm not sure, but guessing that you can measure yours and quite easily order it online (?) Or buy a kit with all kinds - including this one.

Sry for late reply. But yeah, why make it harder than it should be
