I have a 09 ultra classic and my HK radio shuts down when I start the bike, it turns back on after the bike starts, the dealer says it is suppose to do it but I have not seen any other bike do it, and the dealer checked the bike on the showroom floor and it don't do it, so they said the bike on the floor isn't working properly. has any one else have the same problem

 

Voltage drop / spike during startup will cause the radio to cycle off/on.

 

Normal, even my cars do that.
