You plug the bike into a computer and change the fuel map to put more fuel in where needed so you don't run lean. The dealer already has a map to download into the bike for TORs not sure what else is available from people like Tune Boy or one of our members who was working with maps. I can't remember who it was off the top of my head anymore.

I learned all I need to know about life by killing smart people and eating their brains.
