Probably above 3k by now. Shipping costs for all the small things adds up, about a third of that figure. When all is said and done its still a 500 dollar bike. So as was said, best not to look into the cost too much.
For the rear, it was originally cut right past the double wall area behind the shock mounts, slugged, and had a hoop. I've since cut the hoop off, leaving about 3 inch stubs past the shock mounts. Added a 16 gauge flat stock brace at the rear, and another further up right past the stock 'curved' brace. After welding the curved part was tamped down flat with the frame height.
Any stock brackets/tabs were removed.
I do still have the torozzi rearsets, but the right one is slightly bent. It's fixable but would need to be heated and straightened, and after that I don't know how brittle it would be
