Yea I have a ported 76.5cc saw and its in my hand all the time (Much faster than any 50cc in any wood). Back-up only by a 192t stock. Very fast combo the need for a 50cc is not need in my wood. Now to take a 50cc saw and try to get it to proforam like a 70cc saw you will have the extra weight put on it with an ockward pipe and still not be as nice as a 70cc saw not to metion you spent way more and under perform. Oh and putting a Pipe on a saw is nothing like a turbo at ALL!
