My 90 Model at about 1000 ft elevation 60-70 degrees runs best with a 142 main. I had horrendous spooge with a 148.
My bike does have an FMF pipe and answer silencer. Finding the best jetting is trial and error , looking at plugs, being aware of changes in elevation and temperature/humidity as well as oil mixture. ((Phase of the moon and many other things I probably am not mentioning as well)) Doubt one size fits all. I know searching this site has been a great help to me!
