I believe I've seen both done somewhere on the site here.
Looks like the newgen oil screen fits. Any benefit? Aside from the replaceable aspect if you crossthread/strip the pregen drain bolt, does the newgen one hold more oil volume orrrr...? I have an external stand and no center stand, so draining oil while on the side stand isn't really a benefit or problem either way for me. Something I'll consider if it would be helpful, I'll ignore if it's not helpful.

The only thing I might use off this is the metal gasket vs the paper one because those are also interchangeable
