So my '00 YZ426 has been due for a thorough going-thru for some time now. This afternoon I tore into the carb as I was certain the previous owner hadn't done the usual maintenance. It was, well, cruddy for certain. I've been looking at the usual carb kits and I guess I've torn the carb down a little further than would be covered in most cleaning efforts as none of the kits include the gaskets for the area highlighted in the attached diagram + pic.
Anybody have any suggestion as to where I can order a more complete kit with the highlighted gaskets?
