Tuning, it's not witchcraft. It is more like rocket science though. That guy at your local dealership look like a rocket scientist? (Actually neither do I but that isn't the point)
The point is it takes knowledge, not just training to properly tune a motorcycle. For example, It is fairly common practice to tune the front cylinder of a Harley and then simply mirror the tuning parameters over to the rear cylinder and call it done. The downside to this is simple. The front cylinder is out in the breeze running cooler while the rear cylinder is stuck behind that hot front cylinder out of the airflow on an air cooled motor. In other words most shops half-ass the job. I use a systematic approach dialing in each cylinder until I get the tune you need. Power when you need it and economy when you want it.
Yeah, power and economy on the same bike. Isn't it shocking to hear that it is possible. Want fuel economy at 2500rpm on cross country trips but want the low end grunt to pass that semi without downshifting? Piece of cake with a proper tune.
