engine running hot
I had a big bore kit put in my 04 softail. How do I adjust dfo to run richer? I must have an old dfo because their are 4 adjustment screws but not color coded. How do I adjust left to right? anybody?

What kind of DFO is it? I have one on my 05 FXDLI (Techlusion). Maybe you can google their website for owner instructions or technical advice.

Those are similar to the adjusting pots for the Techlusion/RevTech on my 05 FXDLI, my bike is still a 88" motor with stock cams. Using the picture above for guidance, when powered up three lights will come on to test the unit, (G) green, (Y) yellow, (R) red. The injector pulse is being adjusted similar to a carb.
"A" (G )set the arrow to 3 o'clock on the dial, this would be adjusted like a mixture screw on a carb
"B" (Y) set the arrow to 8 o'clock, this acts as the accelerator pump, any time this light is on your are adding fuel, light won't come with gradual increase to 3,000 rpm, will come with a rapid opening on throttle.
"C" (R) set the arrow to 6:30 o'clock, this setting is like a main jet on a carb
"D" set to the arrow to 4 o'clock, controls the amount of fuel above 4,000rpm.
You'll have to dial in your bike to your liking, I have a nice burble when engine is decelerating in gear. And it does seem the heat has been lowered, I also use M1 20W50 oil.
