Rockwell 440cc and a kenbar streaker?

It needs the stock airbox and muffler to run properly. I had put a 440 snowmobile engine in a golf kart. It too didn’t run worth a damn until I did those 2 things.

I ran my other rockwell 440 with no air box and a motorcycle exhaust and it had plenty of power. enough for me to get the tires spinning and crash it into the fence

It’s pouring outside so I don’t think I’m gonna get to do any testing today.
