Chain Guard Extender - Is there one?

Hi

I have recently fitted a Scott e-oiler system and I am getting oil thrown up around the rear seat. I have the same system fitted to another bike without such problems. This bike has a longer chain guard.

Does anyone know if there is an after market option to extend the guard?

Okay, thanks. DIY it is then.

If I make something decent I will post it. Might be some time though with all the other jobs on the go.
