    Lowell porting-what carb jetting???

    Engines out of my ski and I'm sending it to Lowell soon. I have decided to have him bore my 1200 to 1300 along with his cylinder and case porting. I am running Island modded stock carbs with F/A's, no socks. I believe Carl has a 125 mainjet in there, what should I go to?
