I bought my bike used at 207 miles. I installed a TFI about a year ago. I had it dyno tuned and it outputs terrific horse power. I noticed on a recent ride while my son was riding it that it seemed to put out a bit of black smoke and riding behind him, it smelled too rich. While sitting at idle, cracking the throttle puts out black smoke. I checked with the guy I bought it from and found he had the SE download when he installed the SE air cleaners and mufflers. I see in the instructions, the settings are one for stock and one for air cleaner and exhaust with no download. I am wondering where I should set the pots for my bike with download, air intake and exhaust?
