Z1 Engine Paint Pics

Hello does anyone have any stock Z1 engine pictures?

I'm new to these bikes and am looking at a rebuild and I want to get it right.

I'm just wondering what is black and what is not on the engine.

Are the side fins polished or just plain aluminum?
And is it just the sides fins that are non painted or are the fins not painted all the way around the engine.

I've tried the search and came up with some hits on engine painting but the exact answers I'm looking for.

Chemically strip the engine or bead blast?

Also do you guys recommend PJ Engine Epoxy Paint?

Thanks Again!

Hey thanks guys!

I also checked ebay for bikes an found this one some good shots.

So it looks like the non painted fins are on the sides and just curve around the stop and full paint across front and back.

Thanks for the help!
