I would like to see pics of your $450 cylinder porting.I will port the engine to meet your demands; also factor in the pipe. You pay 250 to 500 becuase people are willing to give their money away. I can charge you 500 more if you would like. It does not take me long to port most cylinders, after a few thousand, it gets easy! I can send you pics if you would like.
