I just did a search for "P38" and got about 80 results, so you are doing something wrong.
Anyway the P 38 is just a replacement accelerator pump cover. It has a thicker bottom, and since the pump is spring operated and it continues to spray until the dimple on the pump diaphragm bottoms out on the inside of the pump cover the P38 results in a shortened accelerator pump stroke (and less fuel delivered) relative to stock.
The BK mod does the same thing for '00 and newer Yamaha Flat CR carbs for less money, and it is infinitely adjustable, where the P38 is not.
For older FCR carbs or all non-Yamaha applications you can buy a small wheel collar from a hobby shop to affix to the pump actuating rod outside of the carb body, the collar will bottom on the carb housing acting as a pump stop.
When you figure out the search function search for "wheel collar."
