Carb Heater Info

The RSV is equipped with 4 electric carb heaters, one in each carb. These heaters draw 15 watts of power each, for a total of 60 watts. They are operated by a thermostatic switch located behind the right side cover. The thermostat is calibrated to turn the heaters on at 68ºF and off at 78ºF. The purpose of the carb heaters is to eliminate the possibility of carb icing and to ensure proper performance under certain weather conditions.

Due to the limited charging system output of the bike, some riders have disconnected the heaters to be able to use that 60 watts of power for other accessories such as heated clothing and gloves or additional lighting. After many miles of running with the heaters disconnected, they have reported no drivability or performance problems. Although it is theoretically possible for carb icing to occur, it is believed to be very unlikely due to the number of miles travelled in all weather conditions by those who have done this mod. For those reluctant to totally disable this system, it is possible to connect a switch inline at the thermostat wiring so that the system could be reactivated with the flip of a switch.


Here is a pic of whats behind the right side cover. To disable the heaters, just unplug one of the wires from the thermostat for the carb heaters which is the round silver part on the right. Be sure to cover the bare connector with something to prevent it from shorting.

You can also disconnect them by unplugging this connector (the white one on the left with two wires) under the tank on the left side of the bike.
