Does anyone have a current available carburetor replacement suggestion from OS or Saito. I have access to a machine shop so adapting should not be a problem. I've been unable to get a consistent tune with the stock carb. I can only open the needle 1/2 to 3/4 turn before going overly rich at wot. When trying to lean to a comfortable tune the needle becomes incredibly sensitive and unrepeatable. I'm guessing sloppy tolerances may be blame. Also is there any reason other mounting constraints for the carb being 90 degrees to the inlet? I'm also considering converting to ignition and possibly gasoline.
