HKS has a heat probe to prevent ice.
I took this from the FAQ on the HKS site.
The electric probe warms the carburetor body. It is generally used as a preventative. Unlike Carb Heat systems of conventional aircraft it is commonly left on continuously when operating in climate conditions where carb ice is possible. This does draw from the available electrical power. If running strobes, nav lights, transponder, com radio, etc. it may not be possible to maintain a positive charge rate. (17.5 amps at 12V) Because of the short intake track of the HKS, carb ice has not been as common as with a Continental, for instance. Remember, the cylinder head, to which the intake tube is bolted is running about 300 degrees F. Header wrap is sometimes used to insulate the intake runners effectively warming the carburetors. Alternate solution to deal with potential carb ice would be to pick up hot exhaust air and duct it to the carburetor Body. Conventional ducting through the intake is not a preferred method to deal with carb ice on the HKS
