I had this issue right when I got the bike running and since have done a complete rebuild, it idles okay (no known air leaks on spray test and fresh gaskets and seals) and when I take it off the stand, it just dies. I can bump start and ride or rev a bunch when taking off the stand. Any suggestions?
