A friend of mine has his 6 port engine appart right now and has the sleeves pulled out for a while while he was still driving it. He said as usual that he did loose some low end and gained high end. <Normal. Any ways I think it is important for us to all recognize that when the sixth port is closed at low end we can say that port timing is ,,, well lets use the term normal. It basicaly rune like a 4 port. But at the higher rpm's the sixth ports open and at that moment is when the port timing changes. I got in on this thread late and i tried to read what had already bean written so I hope I am not to redundant. Any ways in my friends engine that is torn appart he has the sleeves pulled out. But when you pull the sleeves out at the end up in their where the end of the cylender is is like a dead end. Any ways he went and put steal epoxy and filled the hole and smoothed it. Now it feals very similar to a stock port. This should make it so that the fuel comes in much more eficiantly with the sleeves removed. Onve again I don't want to start another big argument but I am a real big NA, Carburetor, 4 port, peripheral port, fan and I don't do that much with 6 port stuff. However I do have some friends that run a "huge" street ported 6 port with dual stock 12A nikki 4 barrell carbs. pretty interesting, I wil try and get pics of it on here sometime. Until then, peace.
