is there a sensor on the bike any where that controls idle speed according to tempiture .some times my bike will idle up 1500-2000 rmp if it ´s cold out side ,this after I´ve riden for hour or so then pull into a town.also then if I ajust idle .when bike gets hot ,sitting at light ect. it´ll idle down below what I need to run the fuel injection system ,which is 9.5 volts.I thought there might be a head sencer or something that controls idle. any sugestions would help.1997 ultra classic,injected,stage 2 ,cam,had injecters redone,after market pipes.
