First off how can you tell if you are running lean or rich? I just got my HMF and moto remap done and my cdale seems to back fire. I don't know if it is just the sound of the HMF or if it is running rich. BTW it only seems to back fire when I'm crusin along then "let off the gas". if running rich would cutting a couple of holes in the front plastic help lean it out. Thanks

 

Carry it back to your dealer. They can determine if it's running rich or not.
If they done the re-map and pipe install, I would assume they already compensated for it when the work was done.

If you went with a "mail order" re-map........good luck.
