That was corrected later and Kyle had the right size .005" I had given a wrong size from an old document compiled for me by another party. Jets are not arbitrary in size. They are referenced to the number 100. There is a standard for a number 100 that flows so much fuel in so much time at a fixed pressure. All others are a percentage of 100. 35 is 35% of what a 100 will flow. 125 is 25% more than.

No typo." Final Jepoardy : I found two Keihin slow jets N424-21 and N424-26 (http://www.pjmotorsports.com/keihin_jets_&_parts.htm) The diiference being the length 28 mm vs 23.5 mm. I think its N424-21 Since the Keihin slow jets range in size from (35, 38, 40, 42, 45, 48, 50, 52, 55, 58, 60, 62, 65, 68, 70, 72, 75, 78, 80) and they are $7 each I may buy a set of size 40 and 42.
