Hey guys, one more question - I’m going to be running to 80mm 750 jugs and pistons on my 447 build and saw a video that described drilling two small holes, one above the other, through the piston skirts just under the last ring land to allow oil to splash onto the sides of the cylinders and reduce wear. Is this a common trick? Seems like a good idea to me but wanted to run it by the forum before I start putting holes in things. Thank for reading!
