Congratulations on sorting out your problem. Great feeling when you get it straight -- you don't get that with modern cars.
Personally, I think your side covers and tank look great. If you are into paint, you might try painting the silver part black or a contrasting green. A touch of the same color on the gas tank maybe? Remember, light colors accentuate things and make them look bigger, dark colors make them blend in. The paint job you have does a good job of emphasizing the engine.
There are a couple of guys who post here who have nice looking handmade side covers. One fellow made them an oval shape, another used folded flat aluminum sheet. Once I saw an A65 with A10 oil tank and tool box. Looked great but A10 parts are not so plentiful nowadays and pricey.
How about folding a sheet of aluminum to cover the battery
, polish it up and use a leather strap to retain the battery
. Would look good in tan or black, and a polished brass buckle would look great.
If you cut the brackets off, IMO that would reduce the chance of getting a good price when you sell. Modify only if you are committed to a long term relationship. BTW, the points are pretty easy to live with, especially if you have a timing light and know how to use it.
This Forum is the greatest thing around. Go back and read all you can stand, including British Bikes In General. Many hours of time wasting entertainment.
Good luck and keep us updated.
