I have a 1999 RKC with Thunderheader slip-ons and a K&N air breather. These items were on the bike when it was shipped to Canada. My understanding is after making these changes the bike would have had a new download added. The bike has had the cams replaced (Andrews 21N) and a Dobeck TFI added. Does it need to be put back to the stock download and set up the TFI according to their instructions? The bike is running well, I'm just curious what the knowledgeable folks here have to say. Thanks for any input.
