I put on a zip kit from Zippers last year. It really made the bike run great and sound fantastic, although just a touch too loud for my tastes. After a few hundred miles I got a check engine light and I looked up the error code and it says the rear cylinder is too rich. The bike seems to run great and I have no idea how to make the error code go away or if I need to find someone to set it right. That will mean a long trip as no one in my area has this ability. Can a run the bike like this or will it shut itself down?
