Sealed or Unsealed GX50U
I am looking for a Honda GX50U sealed engine for kids go kart racing. Can you tell me if this is a sealed engine, meaning I believe it has some sort of seal on the crankcase that means it is certified. Thanks

ProductExpert19· 13 years ago
Honda does not offer any type of sealed engine program.

HondaSpecialist· 13 years ago
Honda does not offer any type of sealed engine program. All our engines are manufactured to certain specifications, then delivered (often in bulk) to either a Honda Engine Distributor or another company (OEM, Original Equipment Manufacturer) who then takes the engines and installs them on their equipment (log splitters, pressure washers, go-karts ,etc.). There are no seals, marks, stickers, etc. installed at the factory to seal or otherwise mark an engine to prevent tampering or changes.
You may wish to ask with the official racing organizations about how an engine may be qualified as "sealed" but I'll guess some third-party usually provides this kind of certification and enforcement of the rules on keeping an engine stock for certain racing classes.
Best of luck, -Robert@Honda
