FMF no longer sells an o-ring kit for the KDX200. There's just 1 site that claims the KX series kit is compatible. Does it use the stock 39mm o-ring? Will stock springs work?

There's also some rubber damper rings for one of the hangers. I don't see them on the parts diagram? I can take a pic if no one knows. Thanks

The KX250 rings are larger, the 125's may work - aftermarket kdx top end gasket kits include them.

I think the factory KDX ones will work just fine, or like kawagumby mentioned, aftermarket gasket kits include them.
