New Aztec Kawasaki FS481V 18HP 603CC Retail Kit Propane Engine
Our Take (from the SES Sales Team)
“The Kawasaki 603 cc engine powers much of Aztec's propane line, from the LowRider burnisher to the Sidewinder stripper and the UltraGrind, and this retail kit is that engine converted for propane by Aztec. The base engine is Kawasaki's FS481V, a 90 degree V-twin with overhead valves, cast-iron cylinder liners, a pressurized lubrication system and a dual element air filter with a reinforced primary element. Aztec lists it as an 18 hp engine. The conversion is done under Aztec's PurePower LPG brand with a customized carburetion formula and brand name components, every engine is individually tested, and every conversion gets a catalytic muffler, whether or not the law requires it. Aztec's conversions carry EPA and CARB certification. For a shop that keeps propane burnishers and strippers running, that means a repower with the same engine family the machines were built around. Aztec also sells a preventive maintenance kit for this engine. Send us the make, model and serial number of your machine before you order so we can confirm the fit.”
