Yeah, that is the Suzuki AFI (Automatic Fast Idle). Suzuki really seems to love putting initials on everything.dilbertian said:- When you first start it, maybe the timing and fuel mixture changes around so you here the pace of the idle changing a bit.
If you are hearing a little squeal when the ignition turns on, that is actually the SET valve opening. It is a little noisy for sure. It sounds like a metallic scaping sound, but it only lasts about a second.Windog said:I here a tin sound under tank scrapping. Â

The VTX has the same break-in noises.Maybe even morse.
