Modifying transfer ports on a 372 or any 2 stroke for that matter. I see a lot of pics of people raising the port wall on the cylinder up to the bottom of the flange. I’ve searched quite a bit and maybe the answer was there and I missed it, but what are the negatives to doing this? Weimedog on his videos calls this the “spike special” in which it was supposed to be an easy mod with a Dremel that does not require porting work skill. However this is a large change from stock, and you are enlarging the holes on each side. Does this change the velocity of the charge? Does it slow it down because the bottom of the piston is no longer pushing through a small hole but now a large one? I am more inclined to smooth the ports out rather than enlarge them. One video a guy said that any transition over 7 degrees causes unwanted turbulence. What do you guys think?
