Should I Have the Inner Primary Cover Polished?

The outside primary covers look great when polished. What about the inside primary cover? Is paint an option?

I had mine done, but you can really only go round the outer edge...no point on the mating surface

I've seen it done years ago, but it requires a lot of grinding, sanding and polishing due to the pebble-grain cast finish of most of the part. And when you're done, you can't see most of the work anyway. Also is a pain to get to to keep the shine maintained.

No. It's a Norton.

I polish mine on the top and front.

To make that inner cover look really nice, first grind off the casting marks on the front and back edge...this is a detail most people miss and takes only a few minutes to remove. Smooth everything out and polish that edge. Quickest and easiest way to do all of this is with a rubber expander wheel and paper or Scotchbrite belts...work towards a Trizac 1200 then polish. Bead blast the back side and then spray multiple heavy coats of pure silicon lubricant or Boeshield.

Start to finish you should have a show quality piece in about 30-45 minutes.

Thanks for the input. I bead blasted the inner primary cover with 80 grit glass beads. The piece looks great! I'm very happy with the finish as I am trying not to "over restore" the bike.

When you mentioned polished inner we assumed "over restored". :mrgreen:
