Nemesis upgrade

What is it not doing that it should, or doing that it shouldn't? I added a rear floor pan to mine...mostly to hold tools, and looks.
I have put on a adjustable cassette on the left side...I thought about putting the rear floor pan on...where you get it from?
Other than keeping the components maintained I don't know that I'd update anything. Spindles, king pins, bearings, heim joints, seat, seat struts, axle, etc. is what I'd be ensuring was in good shape.
