I've got an 07 K9 with a 124" and running mean mothers. Plugs are a nice brown color. Jets are .078 & .031

31 and 78 is a good place to start. But also make sure you are not using the enrichener to start. And you might check for intake and exhaust leaks. Black plugs sounds rich, extreme heat sounds lean. ? Also that cam has been known for decel popping esp with out a baffle of some sort.

Here are a variety of jet combinations with a variety of modifications. You may see something here that is similar.

The stock carbs on our bikes are not sufficient enough for the big motors. You can do all you want to the motor with cams etc but if you do not upgrade the carb itself it will never run to its potential.

If you are referring to moving up from an "E" to a "G", I'll agree with that. I would be curious to know how many still run the Super E.

Super G III

Last I'd seen on a thread somewhere Raywood still runs the E carb for better fuel mileage. Maybe he'll jump in here.

Addict -drop down to 31 - if still black lean out your idle mixture. You have mail

 

[AddictJ]

hd dealer should have these right?

 

[AddictJ]

Plugs are showing lean now with the 76 33 jets! They were showing rich before. Not sure what to do now?

The porcilin on the darker is not that bad.

The book calls for gapping your plugs beyween .038 to .042 I gap mine around .036 to .038 and they burn a nice brown color. (NGK)
