anybody have a rough rule of thumb for variance between the pilot jet and the main jet on a keihin 46mm butterfly carb. above 2000 the engine is fantastic. below that it's an entirely different story. it was fine until a carb cleaning and while the carb was apart on the work bench, my granddaughter decided to clean the work area by putting all the jets, O-rings and screws back into my assortment boxes. I just can't seem to get the pilot jetting right.
 
Any mods to the motor? AC, exhaust, cams, head work?

Welcome to The Forum, have a look here Harley Davidson Forums There is more info in the self help section under carbs:s
 
Jack has you covered pretty well in the above link. If you removed the Idle Mixture Screw make sure that the proper o-ring and washer are back on it. They are easy to LOOSE. Don't ask how I know this(lol).

and if you think you've lost the O-ring, check the hole in the carb to make sure it didn't come off the mixture screw and get stuck in there.
don't ask how I know this either :D
