For parts, you could email Wally Kerstetter in Sunbury Pa. He used to sell complete kits for CV carbs including, modified & polished slides, springs needles and jets, but don't know if he still sells the kits.
A few years ago I sent Wally an old carb from my '90 Ultra and in a day or two he exchanged it for one of his polished (looked better than new) carb that worked really well. At that time it cost about $125.00. I think I sent it out on a Friday and had the new carb the next Tuesday. It was ironic because I had previously bought an almost new take off from a '06 for $150 that did not look or work as good as the one Wally did. I had more than that invested because I paid both a Harley dealer and an independent shop to set up the old carb before it went to Wally-I even tried buying a new replacement but they were obsoleted. I could have saved several hundred dollars if I had know about Wally sooner.
