I bought a go kart set up with a nighthawk engine on it, however every number I seem to look up on it comes back as not being a real engine. The numbers are listed below, any help would be greatly appreciated since I need to get gaskets for it.
left side of the engine - serial number: RC38E-2500212
under the serial number on the left: UN-225
thanks, dylan

figured it out, got the cb750L engine, runs like a dream with it being 40 years old.
for anyone trying to figure out based of engine serial alone, this is a complete list but you need the adobe chrome extension
