Good call on the Arco gear reduction starter upgrade. Put one on mine earlier this year, you'll love it.
Nice work on the buffing/polishing. Replacing at least the 1/4" blue striping would be a good bang for the buck in the looks dept. Pretty easy to do and not that costly, but you may be busy doing some other stuff this weekend!
