Something is going on and I don't know what yet. I put jetts in about 6 yr. ago I got to looking in my tool box and found a jet in a bag 42 pilots and 125 main. I've run them for all that long. Use the choke to star the bike. Now I can't put the choke on when I start the bike now or will die when it is cold. I'm going to change plugs now and order 45 pilot, and I've got 130 &145 main in a draw. My try 130 because now with the sidecar can only do 85 mph. The reason I opened the Ideal adjust to 3 turns is the new speedmaster .com that I got them from say'es start with three turns. Rudyr
