I just made this velocity stack for my Saito 1.25. I used a piece of 3/8 ID KS tubing. I slit a piece length wise and kept pushing it together with my miniature vise and re-slitting it with my band saw until it would tightly slip into a choke bracket left over from a choke removal. I had drilled the choke bracket out slightly so the final ID of the stack would be .5mm larger than the carb venturi. I closed the seam and soldered the stack to the bracket using Silver Solder, the stack extends 1/16th inch inside the choke bracket and rests up against one of the white rings from a previous choke removal. My neighbors and a couple of friends are out enjoying their pool so I'll run the engine tomorrow. The length is 1.125 inches at the halfway point of the baloney cut.
