  Due to a great demand for SSI main jets and the limited availability we had them made. These UN-drilled jet blanks can be drilled to any size by the buyer and are great for tuning and vintage racers. Jet sizes are in metric sizes but easily converted to fractional sizes. An #100 jet is 1mm in size, a #140 jet is 1.40mm, and a #160 jet is 1.6mm in size. To use fractional drills, multiply the jet size by .039" A # 100 jet uses a .039" drill, and A # 125 Jet uses a .048" drill. Use the pulldown menu to choose undrilled or drilled type of jet. Dellorto part number #1126. !! SOLD EACH !! Drilled jets have a 1.00mm (.039") pilot hole equal to a #100 size jet. NOTE: Jets only fit 18-30mm SSI carbs with 6mm threaded main jets and do not fit the larger bodied 32-42mm carbs with 7mm jets. They also do not fit SSI carbs with pumper conversations. !!
